From d84df06de3f077adde35aa6ebf0a79895d56700d Mon Sep 17 00:00:00 2001 From: Leslie Richardson Date: Mon, 15 Jun 2026 10:55:18 -0700 Subject: [PATCH 01/77] Add configure-agentic-perf-rules skill MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Installs an always-on rules block into a .NET MAF/Aspire/Foundry agentic app's instructions file (.github/copilot-instructions.md) so coding agents volunteer perf concerns by default — agent count, handoff edges, per-agent model selection, message-history strategy, per-turn token cost, and post-change measurement. The managed block is delimited by sentinel HTML comments and embeds the skill version so updates can preserve user-edited threshold values cleanly. Includes SKILL.md (201 lines), three reference docs (managed-block template, threshold defaults, per-rule rationales), eval.yaml with 5 scenarios covering install / append-preserving / idempotent / version-update / AGENTS.md-stub flows, and a CODEOWNERS entry matching the dotnet-ai convention (@leslierichardson95 @mikekistler — co-owner placeholder).

Default warning when unbounded full-history is used in a multi-turn workflow. +5. **Token / cost surfacing.** Before implementing a non-trivial change to an agent's + prompt, tools, or model, estimate per-turn token cost. Default warnings: more than + 8000 input tokens or more than 2000 output tokens projected per turn, or any change + that adds more than 20% to a measured baseline. +6. **Post-change measurement.** After a non-trivial change to a workflow, propose + running `setup-maf-evals` (or an existing `.Evals` project) to confirm the change is + net-positive — or explicitly note why measurement is not warranted. + +Long-form rationale, examples, and counter-examples for each rule live in +`references/rule-rationales.md`. + +### Step 5: Update the cross-tool stub (if applicable) + +If `AGENTS.md` exists alongside `.github/copilot-instructions.md`, ensure `AGENTS.md` +contains (or has appended) a single line: + +```markdown +> Agentic-perf rules for this project live in `.github/copilot-instructions.md` (managed by `configure-agentic-perf-rules`). +``` + +This avoids duplicating the rules across files while keeping cross-tool agents pointed +at the right source. + +### Step 6: Commit guidance + +If the project is a Git repository and the user wants the change committed, use a single +commit message of the form: + +``` +Install configure-agentic-perf-rules vX.Y.Z + +Adds always-on agentic-perf guidance to .github/copilot-instructions.md. +``` + +Do not commit on the user's behalf without confirmation. + +## Validation + +After the skill runs, the agent must verify: + +1. **File exists** at the resolved target path. +2. **Sentinel comments present** with matching `BEGIN`/`END` markers and a parseable + version in the `BEGIN` comment. +3. **Threshold frontmatter parses** as valid YAML (no syntax errors introduced). +4. **All six rule sections** are present, in the canonical order. +5. **Round-trip:** re-running the skill against the now-updated file is a no-op (reports + "already current").

Default ceiling: 2 LLM-routed +edges traversed per user turn. + +**Why it matters.** Every LLM-routed edge is an additional LLM call before the user +gets a response. Two routed decisions per turn (e.g. "router → specialist", "specialist +→ done-or-continue") is the practical latency ceiling before users notice. +Free-form-everywhere graphs also amplify decision-quality variance. + +**When LLM routing is justified.** The decision genuinely requires reading the user's +intent — for example, "is this answer detailed enough to grade?" or "which specialist +domain does this question belong to?". When the decision is mechanical ("after coach +runs, always go back to interviewer"), use a deterministic edge. + +**Concrete pattern (good):** +- Interviewer ↔ Coach with one LLM-routed edge from Interviewer ("ready to grade?") + and a deterministic edge back from Coach (always returns to Interviewer for the next + question). + +**Concrete pattern (bad):** +- Five specialists in a fully-connected handoff graph where every transition is + LLM-routed. Symptom: Copilot constantly proposes new edges as the workflow grows. + +--- + +## 3. Model selection + +**Rule.** Before defaulting to a frontier model (e.g. `gpt-4o`), name the agent's role +and pick from the role→model matrix in the `select-agent-models` skill. + +**Why it matters.** A frontier model on a router/triage agent costs roughly 10x more +per token than `gpt-4o-mini` and is often *worse* at the routing job (frontier models +are tuned for nuanced generation, not cheap classification). The default-everything-to- +gpt-4o pattern is the largest single source of unnecessary spend in agentic apps. + +**Quick role mapping (full matrix in `select-agent-models`):** + +| Role | Recommended class | +|------|-------------------| +| Router / triage / "is this done?" | small-fast (gpt-4o-mini, gpt-5-mini, phi-4) | +| Classifier / scorer with structured JSON | small + JSON mode + low temp | +| Summarizer / extraction | small with high context | +| Open-ended reasoning / planning | reasoning class (o1, o3-mini) | +| Tool-heavy specialist | mid-tier with strong function-calling fidelity | +| Creative generation / nuanced writing | frontier (gpt-4o) | + +**When frontier is justified.** The agent's job is genuinely creative or nuanced +generation, or it must follow complex instructions reliably. Routers and scorers +almost never fall in this bucket. + +--- + +## 4. Message-history strategy + +**Rule.** Before sending the full conversation history to an agent, state the bound — +turn count, token cap, summarization point, or retrieval strategy. + +**Why it matters.** Per-turn token cost grows linearly in history length. A workflow +that sends 50 turns of history into every LLM call is paying for 50 turns of attention +on every single response. This is the most common token-bloat pattern in handoff-style +workflows, where every agent in the chain re-sees everything. + +**Acceptable bounds (in order of preference):** + +1. **Sliding window:** keep only the last N turns. Cheap, simple, bounded. +2. **Summarization checkpoint:** every M turns, replace the oldest portion with a + summary. Preserves long-range context with a fixed-size payload. +3. **Retrieval / per-agent context:** each agent receives only the messages relevant + to its role, not the full transcript. Highest engineering cost; biggest savings. + +**When unbounded full history is justified.** Single-shot interactions (no multi-turn +loop), or workflows where the entire history is short by construction (e.g. always +under 2K tokens). + +--- + +## 5. Token / cost surfacing + +**Rule.** Before implementing a non-trivial change to an agent's prompt, tools, or +model, estimate per-turn token cost. Default warnings: more than 8000 input tokens or +2000 output tokens per turn, or any change that adds more than 20% to a measured +baseline. + +**Why it matters.** The window between "looks fine in dev" and "$5K/month surprise" is +measured in token counts, and most contributors do not look at token counts at dev time +unless something is on fire. Surfacing projected token cost *before* implementation +catches the bloat at the cheapest possible moment. + +**How to estimate.** Token count is roughly characters / 4 for English prose; +structured output is denser. For prompt changes, count the new prompt body. For tool +additions, count the schema + description per tool * expected frequency.

Runs seven check classes (topology, tool inventory, message-history strategy, prompt weight, parallelism, OTel coverage, model assignment) and writes a severity-tagged Markdown report to .copilot/perf-reports/audit-.md plus latest-audit.md. Findings carry file:line citations, evidence, a one-paragraph why, and a concrete next action that can route into select-agent-models, setup-maf-evals, or configure-agentic-perf-rules. Never edits source. Includes SKILL.md, eight reference docs, eval.yaml with five scenarios (clean / sprawl / full-history / prompt-bloat / missing-otel), and a CODEOWNERS entry matching the dotnet-ai convention.

Pass 3 also gains a final sub-step that asks the user once whether to run any of the routed skills now, mirroring the new step 6 in the audit skill.

Added to ichatclient-detection.md with a note that the argument is the connection-string name. 2. **Connection-string setup not surfaced for standalone runs.** When the app uses Aspire orchestration, `ConnectionStrings:` is populated by the AppHost — but `dotnet test` runs outside the host and gets a silent missing-config NRE on first real-agent run. Added a `Connection-string setup for standalone test runs` section to ichatclient-detection.md that surfaces both user-secrets and env-var setup paths and points to `azd env get-values`. 3. **WordCountEvaluator implementation not pinned.** The catalog called the evaluator out as `always scaffolded (custom)` but never gave a verbatim template. Added the Learn-doc canonical implementation to evaluators-catalog.md so every scaffold gets the same (correct) IEvaluator skeleton. Validated end-to-end against ELI5Agent: scaffolded ELI5Agent.Evals.Tests, `dotnet test` exits 0 in stub tier with 4 scenarios x 4 metrics (Words/BLEU/GLEU/F1) producing a 670 KB report.html. Real-judge tier deferred (no Azure creds set up locally for ELI5Agent — itself the trigger for finding 2).

New references/metrics-glossary.md authored as the source of truth for metric definitions/scales/thresholds across NLP, Quality, and Safety tiers. Includes the canonical Reporting/MetricsGlossary.cs template that the skill emits into .Evals.Tests/Reporting/. 2. Factory template in references/ichatclient-detection.md now wraps DI resolution in try/catch and throws a friendly InvalidOperationException naming the connection-string key + the exact 'dotnet user-secrets set' command + the env-var alternative + 'azd env get-values' pointer. Replaces the silent NRE that ELI5Agent dogfooding hit when EVAL_USE_REAL_AGENT=1 with no creds set up. 3. Two new eval.yaml scenarios bind the new behavior: - scaffold-emits-metrics-glossary: asserts MetricsGlossary.cs exists, references metrics-glossary.md, has [AssemblyCleanup] - factory-emits-friendly-secrets-diagnostic: asserts AgentChatClientFactory mentions 'dotnet user-secrets' + 'ConnectionStrings' 4. Captured two MSTest constraints that turned up while implementing the glossary writer: - quality-modes.md ReportingConfig: ExecutionName must be cached at class load, NOT re-evaluated per call (otherwise AievalReport and MetricsGlossary land in different timestamped folders 5 s apart) - metrics-glossary.md template now declares MetricsGlossary as a plain static class; MSTest forbids more than one [AssemblyCleanup] per assembly (UTA014). Glossary write is chained from AievalReport's single AssemblyCleanup, wrapped in try/catch so a glossary-write failure doesn't mask the report.

Pulled prose-heavy sections into references and kept SKILL.md focused on decision-relevant content. - Step 3 (Scaffold): replaced 27-line file tree with a one-sentence summary + link to project-template.md. Kept the post-write powershell as a fenced code block so the agent has concrete commands. - Steps 4-9 (telemetry/quality/compare/safety/panel/CI): collapsed bulleted prose into 3-4 line stubs that retain the decision facts (default ON/OFF, opt-in semantics, env knob) and link the corresponding reference. - Step 11 (Surface in chat): added the metrics-glossary.md path to the 'Paths' bullet and to the trailing 'see also' line. - ## Common pitfalls: extracted to references/common-pitfalls.md (also adds two new entries from this work: the multi-AssemblyCleanup MSTest constraint and the AgentChatClientFactory friendly-NRE pattern). SKILL.md keeps a one-line link. - ## References: trimmed each bullet to one short line; consolidated the three external links onto a single line. Net effect: SKILL.md 14,238 -> 10,449 chars, 265 -> 189 lines, 3,574 -> 2,672 BPE tokens (-25%). Validator still passes; eval.yaml scenarios are unaffected (assertions are file-based, not prose-based).

Fix: factory template now calls builder.Configuration.AddUserSecrets(typeof(...).Assembly, optional: true). 2. services.ai.azure.com hostname strips dashes from the resource name (foundry-abc -> foundryabc.services.ai.azure.com). The legacy properties.endpoint value points at cognitiveservices.azure.com which 404s for the /models route. 3. Foundry resources provisioned by Aspire/azd usually have disableLocalAuth=true. Key-based auth returns 403; drop the Key= segment and rely on DefaultAzureCredential. Updates: - references/ichatclient-detection.md: factory template adds AddUserSecrets; diagnostic message now lists Entra and Key options + endpoint gotchas. - references/project-template.md: GlobalUsings.cs adds Microsoft.Extensions .Configuration / .DependencyInjection / .Hosting (needed by the factory). - references/common-pitfalls.md: 3 new entries covering the above. - SKILL.md: step 11 now surfaces the exact 2-command judge-promotion path. - tests/dotnet-ai/setup-maf-evals/eval.yaml: new factory-loads-user-secrets-explicitly scenario.

Compare mode -> opt-in (step 2 #4 + step 6). Largest scaffold for least-common surface; users opt in if they actually need matrix.json side-by-side. Scaffold step now only emits Compare/* on opt-in. 2. Step 11 chat output restructured to lead with Quality as the headline evaluation. NLP framed as the zero-config sanity check (still on by default so first \dotnet test\ produces a real report). Safety + Compare listed as additional categories below. Step 2 tier table re-ordered with Quality on top and a 'Default' column for clarity. 3. New common-pitfalls section 'Tuning Quality for stylistic agents' covering the case where ELI5 / summarizer / strict-format / persona agents get punished by generic rubrics in CompletenessEvaluator and EquivalenceEvaluator. Includes three remediation patterns: - drop offending evaluators per app - rewrite goldens in agent voice - custom rubric-driven evaluator evaluators-catalog.md now has the full RubricEvaluator template (reads Quality/rubric.md, judges via the active IChatClient, emits a RubricFit numeric metric with rationale). Step 11 surfaces this caveat on first scaffold so users don't see bad Quality scores against a bad-fit rubric and conclude their agent is broken. eval.yaml adds three smoke assertions: - compare-mode-is-opt-in-not-default - pitfalls-doc-warns-stylistic-agents-fail-completeness Validator green (9 skills + 1 agent + 1 plugin).

QualityTests uses run.ChatConfiguration!.ChatClient (the cached wrapper) for the agent call by default, only falling back to the uncached factory when EVAL_JUDGE_DEPLOYMENT_NAME splits judge from agent. Previously every run created a fresh uncached agent client and the agent's varying output guaranteed judge cache misses too. 2. Drop the executionName argument from DiskBasedReportingConfiguration.Create. executionName is part of the cache scope -- passing a fresh per-run timestamp guaranteed misses regardless of input. Report folder timestamping moves to the new EvalEnv.ReportFolder (EVAL_REPORT_FOLDER env var). 3. SKILL.md step 11 + common-pitfalls.md rewritten to explain the cache payoff: first run ~60s populates _store/cache/, every subsequent run against unchanged inputs ~5s with zero LLM cost. Compare mode keeps a stable per-entry executionName for cache reuse across compare runs. ichatclient-detection.md documents the override-splits-cache trade-off.

Mirrors the metrics-glossary.md pattern from setup-maf-evals v2. - scan / configure / select: new references/common-pitfalls.md capturing dogfooded false-positive patterns (MA4 in AppHost is expected, MA1 false-fires on 1-agent apps, O3 in MEAI source is normal, sentinel parsing must fail-closed, role classification edge cases, etc). - agentic-perf-reviewer.agent.md: inline Common pitfalls section (agents have no references/ folder by convention). - tests/dotnet-ai/agentic-perf-reviewer/eval.yaml: 11 routing- discrimination scenarios (4 should-invoke, 4 should-defer-to- optimizing-dotnet-performance, 3 should-route-to-child-skill).

Original motivation for select-agent-models was 'Copilot always defaults to gpt-4o when scaffolding agents.' The skill grew well past that — recommend/plan/ apply modes, role-model matrix doc, registry-currency questions, greenfield plan-mode follow-on, etc. — and Foundry's model-router covers the per-request piece better than the skill ever could. Net change: minimum viable fix lives where it always should have — in rule #3 of the configure-agentic-perf-rules managed block that Copilot already reads on every turn. configure-agentic-perf-rules (bumped to v0.2.0): - Rule #3 in managed-block-template.md is now self-contained and prescriptive: a role-pick table covering router/validator/formatter/ worker -> small-fast; planner -> reasoning-class; creative -> frontier. Calls out Foundry model-router as the recommended worker pick when prompt length varies. Says 'stop and ask if unsure; do not silently default to gpt-4o.' - rule-rationales.md rule #3 mirrors the new table with why-it-matters + when-frontier-is-justified + 'state the why in code' guidance. - Removed all references to select-agent-models from NOT-WHEN / companion-skills sections. scan-agentic-app-perf: - MA1/MA2/MA3 'Next' actions now point at rule #3 of the managed block instead of select-agent-models. 'Ref:' fields updated. - check-id-glossary.md, common-pitfalls.md, report-template.md, SKILL.md description + follow-up offer updated to drop the skill reference. setup-maf-evals: - Description NOT-WHEN no longer mentions select-agent-models. - Follow-up recommendation after telemetry/quality runs now references 'a model swap per rule #3' instead of the deleted skill. - aspire-dashboard-panel.md drops the cross-reference. agentic-perf-reviewer.agent.md: - Description + Skills-used drop select-agent-models. - Pass 2 model-finding route now points at configure-agentic-perf-rules. - Pass 3 follow-up letters condensed from 4 to 3 (A=rules, B=evals, C=stop). - Single-agent-app pitfall reworded: rule #3 covers single agents too, no abort-to-skip needed.

Skip step 1's "abort if < 2" guard in this mode. - -Continue to step 2 with the user-declared roles instead of classifying -from source. - -### 2. Classify each agent's role - -Use `references/role-model-matrix.md`. Roles are: - -- **router** — picks the next agent or tool. Short prompt, deterministic - behaviour preferred. -- **planner** — decomposes the task. Reasoning-strong; output drives - every downstream call. -- **decomposer** — splits work into N parallel items. Reasoning-medium. -- **worker** — does the unit-of-work the planner described. Medium quality; - most calls happen here so latency dominates. -- **validator** — yes/no/score on a small input. Deterministic, small - output. -- **formatter** — renders structured output (JSON, Markdown). Deterministic, - small output. -- **summarizer** — compresses chat history. Medium reasoning, often run - hot. - -If an agent does not cleanly map to one role, mark its role as -`unclear` and recommend that the user review it. - -### 3. Look up recommended model per role - -`references/role-model-matrix.md` contains the canonical recommendation -table. The matrix has columns: - -- Role -- Recommended model (primary) -- Acceptable alternatives -- Avoid -- Rationale (latency / quality / cost trade) - -### 4. Build the plan - -For each agent, produce a row: - -```yaml -agent: -current_model: -role: -recommended_model: -delta: same | upgrade | downgrade -rationale: -``` - -Aggregate notes: - -- Net cost change estimate (qualitative: ↓ / ↔ / ↑) -- Net latency change estimate (qualitative: ↓ / ↔ / ↑) -- Risks to validate (e.g. "downgrading requires a quality eval first") - -### 4a. Plan-mode extras — deployment shape - -In `plan` mode only, after step 4 also produce a **deployment-shape** -recommendation derived from the per-agent rows: - -- Group agents by `recommended_model` and emit one Foundry / Azure - OpenAI deployment alias per distinct model id. -- Use stable alias names (e.g. `chat`, `chat-high`, `chat-reasoning`) - not the model id directly, so the AppHost stays decoupled. -- For each alias, list which agents will resolve it. - -Also emit a **verify-checklist** the user runs after wiring the code: - -1. Re-run `select-agent-models` in `recommend` mode against the built app. -2. Confirm `delta: same` for every agent — that means the plan held. -3. Any `delta: upgrade|downgrade` means a role was classified - differently from source than the user declared at plan time — - reconcile before continuing. - -### 5. Write the recommendation file - -In `recommend` mode write to: - -- `.copilot/perf-reports/model-plan-.md` -- `.copilot/perf-reports/latest-model-plan.md` - -In `plan` mode write to: - -- `.copilot/perf-reports/model-plan-design-.md` -- `.copilot/perf-reports/latest-model-plan-design.md` - -The two file series stay separate so a later `recommend` run can sit -next to the original design-time plan and the verify-checklist can -compare them. - -Layout in `references/plan-template.md`. - -Surface in chat: per-agent row plus the aggregate notes plus the file path. - -### 6. Apply mode (only if user explicitly asks "apply" / "make the -changes") - -Apply mode is **off by default**. To run it, the user must say "apply", -"make the changes", "switch to recommended models", or similar. - -**Confirmation contract** — the initial apply request only enables -preview mode. The actual write requires a *second* user response after -the diff is shown. Wording in the initial request like "apply and -confirm", "yes do it", or "proceed" is treated as *intent*, not as -*confirmation* — the agent must still show the diff and ask. - -Steps: - -1. **Provider resolution.** Detect whether the project uses public - OpenAI ids, Azure OpenAI deployment aliases, Foundry deployments, - or another provider: - - Check the AppHost connection string type (`AddAzureOpenAI` vs - `AddOpenAI` vs others). - - Check `appsettings.json` for keys ending in `-deployment-name`, - `-deployment`, or values that look like custom names (not the - OpenAI public id pattern). - - If Azure is detected, refuse to write a public OpenAI id like - `gpt-4o-mini` directly. Map the recommendation to an existing - deployment alias by: - a. enumerating deployment aliases from `appsettings.json` / - AppHost parameters, and - b. asking the user to pick which alias maps to each role, or - c. recommending creating a new deployment if no suitable alias - exists (and stopping apply mode in that case). -2. **Pre-write validation.** For every file that would be modified, - verify it parses (JSON / C# compiles via `dotnet build` dry-run on - the AppHost). If any target file is unparseable, abort apply mode - before any write. -3. **Diff preview.** Show a unified diff of every change you intend to - make: - - AppHost connection-string updates / parameter values - - Per-agent `IChatClient` registrations - - `appsettings.json` model-id keys -4. **Confirm.** Ask the user to confirm.

Do not declare - success on a failing build. -7. **Recommend follow-up.** After a successful apply, recommend running - `setup-maf-evals` quality mode to validate no quality regression. - -If the user says no or anything other than yes, discard the diff and -leave files untouched. - -## Validation - -After read-only mode: - -- A new file exists at `.copilot/perf-reports/model-plan-.md`. -- `latest-model-plan.md` exists and matches the timestamped file. -- The plan lists every detected agent with a row. - -After apply mode: - -- The diff was shown and confirmed before any file write. -- All touched projects build (`dotnet build` exit 0). -- The plan file records the apply timestamp and which agents were modified. - -## Common pitfalls - -- **Applying without confirmation.** The default is recommend-only.

After moving role-aware model selection into rule #3 of configure-agentic-perf-rules, the agent's orchestration logic collapsed to: - run scan-agentic-app-perf (Pass 2) - route MA* findings to configure-agentic-perf-rules - route O* findings to setup-maf-evals That's logic Copilot already does organically from the skills' descriptions and the scan's existing 'ref:' fields + step-6 routing offer. The agent was adding ~70% ceremony for ~30% real value. Net change: - DELETED agents/agentic-perf-reviewer.agent.md (~180 lines) - DELETED agents/ directory (now empty) - Removed 'agents' key from plugin.json and .codex-plugin/plugin.json - The one unique guard worth keeping ('don't recommend a model downgrade without an evals quality follow-up') migrated into scan-agentic-app-perf SKILL.md common pitfalls. - The other 'don't pre-confirm apply-mode writes on user's behalf' guard already lives in scan-agentic-app-perf step 6.4. Users now invoke the skills directly: - 'scan my agentic app' -> scan-agentic-app-perf (which offers its own A/B/C follow-up menu) - 'install perf rules' -> configure-agentic-perf-rules - 'wire up evals' -> setup-maf-evals Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com> --- plugins/dotnet-ai/.codex-plugin/plugin.json | 3 +- .../agents/agentic-perf-reviewer.agent.md | 183 ------------------ plugins/dotnet-ai/plugin.json | 3 +- .../skills/scan-agentic-app-perf/SKILL.md | 6 + 4 files changed, 8 insertions(+), 187 deletions(-) delete mode 100644 plugins/dotnet-ai/agents/agentic-perf-reviewer.agent.md diff --git a/plugins/dotnet-ai/.codex-plugin/plugin.json b/plugins/dotnet-ai/.codex-plugin/plugin.json index 4981aba703..20fbc8bec8 100644 --- a/plugins/dotnet-ai/.codex-plugin/plugin.json +++ b/plugins/dotnet-ai/.codex-plugin/plugin.json @@ -2,6 +2,5 @@ "name": "dotnet-ai", "version": "0.1.0", "description": "AI and ML skills for .NET: technology selection, LLM integration, agentic workflows, RAG pipelines, MCP, and classic ML with ML.NET.", - "skills": ["./skills/"], - "agents": ["./agents/agentic-perf-reviewer.agent.md"] + "skills": ["./skills/"] } diff --git a/plugins/dotnet-ai/agents/agentic-perf-reviewer.agent.md b/plugins/dotnet-ai/agents/agentic-perf-reviewer.agent.md deleted file mode 100644 index b5633494ee..0000000000 --- a/plugins/dotnet-ai/agents/agentic-perf-reviewer.agent.md +++ /dev/null @@ -1,183 +0,0 @@ ---- -description: "Reviews .NET agentic applications (Microsoft Agent Framework + Aspire + Foundry) for performance, cost, and reliability issues across topology, tools, message history, prompts, parallelism, OTel coverage, and per-agent model selection.

Cryptic codes -> human-readable slugs. Findings used to be tagged with MA1, TI4, PW3, etc. — codes that were stable + greppable but required readers to flip to a glossary file every time. The prefix-routing case (e.g. 'MA* -> select- agent-models') that justified the convention is gone now that select-agent-models and the orchestrator agent are retired. Schema: check_id: T1 | T2 | TI1 | ... | MA4 becomes: check: . where category is one of topology / tools / history / prompt / parallel / otel / model and the descriptor names the actual issue. Examples: MA1 -> model.same-default MH1 -> history.full-share TI4 -> tools.description-too-long O1 -> otel.missing-sdk No glossary lookup needed — the slug self-describes. check-id-glossary.md -> check-glossary.md with a new slug -> description table. 2. Pruned arbitrary-threshold checks. Five checks were taste calls dressed up as audit findings; they fired on legitimate designs as often as on real bloat: - T1 'agent count > 3' (DELETED) - T2 'LLM handoff edges per turn > 2' (DELETED) - TI1 'tools per agent > 8' (DELETED) - PW2 'few-shot examples > 3' (DELETED) - P1 'sequential awaits over independent inputs' (DELETED; general .NET concurrency anti-pattern, belongs to optimizing-dotnet-performance) Each deprecated check leaves a 'What used to live here' breadcrumb in its category file so users grep-finding the old name see why it was removed and where the underlying concern is now addressed.

From b0488de7c33e443b9f7da190797b3f923a17ede9 Mon Sep 17 00:00:00 2001 From: Leslie Richardson Date: Wed, 24 Jun 2026 13:42:12 -0700 Subject: [PATCH 36/77] refactor(scan-agentic-app-perf): collapse output to a single overwritten scan.md MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Dogfood feedback: three generated files per run (scan-.md + latest-scan.md + check-glossary.md) plus a new timestamped file every scan made even a clean repo's .copilot/perf-reports/ look like a hoarder's basement after a week. The slug rename made the glossary file redundant anyway — 'history.full-share' is self-describing in a way that 'MH1' never was. Changes: - Single output file: .copilot/perf-reports/scan.md, overwritten on every run. No timestamped copies, no latest-* mirrors, no per-run glossary file. - Category legend is inlined into the report (the blockquote at the top of '## Findings') so readers see what topology/history/model/ etc. mean without leaving the file. - references/check-glossary.md remains as a dev-facing catalog (for skill maintainers adding new checks); it is explicitly NOT copied into user repos. - references/report-template.md updated with the new filename + the inlined legend block. - Validation contract simplified: one file exists, has a '## Findings' section, counts match chat. - Multi-AppHost case: per-host filename is now scan-.md (still overwritten each run, no timestamp suffix). Git is the history mechanism if anyone wants one — the skill no longer reinvents version control by hand.

New apps should prefer the OpenAI/v1 API + stable OpenAI SDK via `AddOpenAIClient(...).AddChatClient(...)`. This commit teaches the setup-maf-evals skill about both paths: - `references/ichatclient-detection.md`: add the `AddOpenAIClient(...).AddChatClient(...)` row to the detection table, mark the Azure.AI.Inference row as legacy, and add a deprecation callout linking the Foundry migration guide. - `references/common-pitfalls.md`: split the existing reasoning-model `max_tokens` pitfall into a short-term workaround (non-reasoning judge) and a durable fix (migrate to OpenAI/v1 SDK, which natively uses `max_completion_tokens`). Link the migration guide and dotnet/extensions#7580 which originally surfaced this for us. No detection-logic changes: the legacy Azure.AI.Inference pattern is still detected and supported exactly as before.

Topology framing — .NET agentic apps are not always Aspire-based. The skills already worked against plain console / ASP.NET Core / worker service shapes, but the SKILL.md descriptions implied Aspire+Foundry were required. Broaden: - scan-agentic-app-perf: `(MAF + Aspire + Foundry)` -> `(MAF; Aspire/Foundry optional)` - setup-maf-evals: `(MAF + Aspire + Foundry)` -> `(MAF; Aspire/Foundry optional)` - configure-agentic-perf-rules body: `typically with Aspire` -> `with or without Aspire/Foundry` Add a brief 'Supported topologies' body section to scan-agentic-app-perf and setup-maf-evals listing the four target shapes and noting that AppHost-specific checks are skipped when no AppHost is detected. 2. WHEN / NOT-WHEN phrasing harmonized across all three skills. The configure-agentic-perf-rules description was using `USE FOR` / `DO NOT USE FOR`; aligned with the other two on `WHEN` / `NOT-WHEN`.

Eval schema compliance: replace 'text:' with 'value:' in file_contains/output_contains assertions (38 in setup-maf-evals, 7 in scan-agentic-app-perf). The skill-validator EvalSchema only recognizes 'value'; 'text' would fail at /evaluate time. 2. scan-agentic-app-perf report path consistency: - Frontmatter said 'scan-.md'; aligned with the body contract (single overwritten 'scan.md'). - Tests updated: 'latest-scan.md' -> 'scan.md' (matches contract). - Body contract calls out the multi-AppHost exception explicitly (per-host 'scan-.md', already documented in common-pitfalls.md). 3. configure-agentic-perf-rules: removed stale 'Default ceiling: 3 agents' and 'Default ceiling: 2 LLM-routed edges' from SKILL.md workflow step 4. v0.3.0 retired hard ceilings in favor of 'justify the add' guidance; these two lines were missed in the original refactor. Skipped (intentionally): version pin alignment in safety-mode.md and evaluators-catalog.md. Keeping those loose; project-template.md is the single source of truth for the concrete preview pin.

In non-interactive eval/autopilot runs the agent halted to ask and produced zero artifacts, failing every file assertion (tier-banner 3->1, scaffold-emits-metrics-glossary 2.7->1.7, factory-loads-user-secrets 3.3->1.7, etc). Reword Step 2 to proceed with documented defaults and state assumptions, while still gating the genuinely destructive actions (update-mode overwrites, AppHost panel edit). 2. eval.yaml: the 3 doc-knowledge scenarios asserted file_contains on ../../../plugins/... paths that don't exist in the eval sandbox, so they failed for both baseline and skilled arms and tested nothing.

Two remaining setup failures were not skill regressions: - scaffold-evals-tests-project-fresh: the DiskBasedReportingConfiguration assertion checked QualityTests.cs, but per the skill's own template (quality-modes.md) that type lives in Reporting/ReportingConfig.cs; QualityTests.cs only calls ReportingConfig.ForQuality(). The faithful scaffold therefore failed the assertion, dragging taskCompletion to 0 on both arms (incl. the +0.48 plugin arm). Point the assertion at the right file. - scaffold-with-safety-tier: the plugin arm timed out at 480s mid-scaffold (1.87M tokens) and never finished SafetyTests.cs.

Handle the no-solution (file-based AppHost) case for 'dotnet sln add'. Also stop hard-authoring package versions in the skill: GA eval + hosting packages are added with 'dotnet add package' (no --version) so they resolve to latest stable; the still-preview evaluators (NLP, Safety) use '--prerelease'; and the aieval tool manifest is generated via 'dotnet new tool-manifest' + 'dotnet tool install' rather than hand-written with a pinned version. The hosting NU1605 floor (>= 10.0.1) is satisfied automatically by latest stable, so no explicit pin is needed. references/ docs (project-template, dotnet-tools- manifest, common-pitfalls, evaluators-catalog, safety-mode) now describe this version policy; remaining version numbers are labeled illustrative snapshots. Verified end-to-end on a throwaway app (net10.0, MSTest 4.0.1 MTP-native, all packages resolve, build + dotnet test green).

Reading them all exhausts the turn budget before anything is written. - Add references/default-scaffold.md: the complete, copy-pasteable body of every default-mode file (Telemetry + Quality + NLP + Reporting + Wire) in create order, so the agent reads ONE doc and creates the whole project. Defines the previously-undefined helpers (Wire, ProjectRoot/RepoRoot, loaders, Thresholds, records) so the emitted project is self-consistent. - SKILL.md step 3: read default-scaffold.md once and create files first; mark the network-bound dotnet steps (add package / tool install / build / test) as explicitly deferrable. Success = files on disk, not a green build. dotnet new stays the default shell-creation step. - project-template.md: point at default-scaffold.md for the default modes. Verified: fresh extraction of the doc into a throwaway MSTest project builds clean and 6/6 tests pass offline in stub tier; reports write and the aieval tool absence degrades gracefully.

Rebalance the workflow so the chat answer is primary: - Reframe execution-discipline: chat response is the deliverable; scan.md is a persisted copy. Remove the file-first framing (the prior 'write the report FIRST, before any analysis' directive starved the chat answer). - Analyze first, then present findings in chat AND persist to scan.md; the chat summary is the terminal step. - On a small app, read sources directly and skip the detection scripts (a large-codebase accelerator) to save the turn budget for the answer. - Make step 5 (surface in chat) a hard requirement: never end with an empty or one-line message.
