Do not anchor on the producer just + because the broken data appears to originate there — the consumer's + retry policy, fallback path, and ability to differentiate cause buckets + locally are usually the cheapest fix and the easiest to overlook. +3. Edit the findings doc to add or refine findings (one numbered subsection + per finding, with concrete evidence — file:line refs, command output, or + test results). You may also push back on prior agents' claims, mark them + disputed, or note unknowns. Aim to converge on a complete, defensible + explanation. + + The doc has a "## System under investigation" section. Fill it with a + small diagram (ASCII or mermaid) the first turn the system is + identified, and refine it as understanding grows. For queue/worker + shapes, the diagram should show producer → input → consumer → retries + → cost amplification. Two boxes and an arrow beats a paragraph. + + Do NOT add a "## Recommendations" or "## Action items" section. + Investigations end at the Conclusion. Once consensus is reached, the + user converts findings to work via `+"`marvin plan --from-investigation"+` + <collab-id>`+"`"+`.

After your edits, rewrite it so it reflects + the current best answer — not the original question, and not a list + of what changed this turn. 2–4 sentences covering: the question, the + answer (root cause / conclusion), and the single most important piece + of evidence.

Each spawned process has its own env, so multiple worktrees and multi-agent runs are correct by construction (no shared marker file, no race). +3. **For non-launchable agents** (cursor, opencode, factoryai-droid): `RunMarkerFallback` writes a `PendingReviewMarker` file and prints guidance — the user opens the agent themselves and runs the skills. Single shared file (`review/marker_fallback.go`); adding new non-launchable agents is a registry entry, not a new file. +4. The agent runs the review skills; the session ends naturally. +5. On the next `git commit`, the PostCommit hook condenses the review session into the checkpoint on `trace/checkpoints/v1`, with `Kind` and `ReviewSkills` recorded in `CommittedMetadata`. +6. The `CheckpointSummary` sets `HasReview = true` for O(1) lookup. `HasReview` is an umbrella "any review happened" flag — future review kinds (e.g. manual review) should also set it. +7. `trace status` and the re-run guard read `HasReview` from the checkpoint metadata (no commit history walking). + +## Checkpoint Metadata + +Review metadata is stored at two levels on `trace/checkpoints/v1`: + +- **`CommittedMetadata` (per-session)**: `kind: "agent_review"`, `review_skills: ["/skill1", "/skill2"]`, `review_prompt: "..."` +- **`CheckpointSummary` (per-checkpoint)**: `has_review: true` (umbrella; set when any session in the checkpoint has a review-kind `Kind`) + +## Architecture + +- **`AgentReviewer` interface** (`cmd/trace/cli/review/types/reviewer.go`): per-agent contract with `Name() string` and `Start(ctx, RunConfig) (Process, error)`. Each launchable agent implements this in its own package. +- **`ReviewerTemplate`** (`cmd/trace/cli/review/types/template.go`): shared scaffolding (Spawn → pipe stdout → run parser → forward events → close). Each agent supplies only its `BuildCmd` (argv/env) and `Parser` (stdout-to-Event stream). +- **`Sink` interface**: consumers of the event stream. Production sinks: `DumpSink` (post-run per-agent narrative), `TUISink` (Bubble Tea live dashboard with Ctrl+O drill-in), `SynthesisSink` (opt-in y/N cross-agent verdict). Sinks are composed by `composeMultiAgentSinks` based on TTY detection. +- **`Run(ctx, reviewer, cfg, sinks)`** (`cmd/trace/cli/review/run.go`): single-agent orchestrator. Forwards events to all sinks via `AgentEvent`, calls `RunFinished` once at end with a populated `RunSummary`. Sink dispatch is serialized; sinks need not internally synchronize. +- **`RunMulti(ctx, reviewers, cfg, sinks)`** (`cmd/trace/cli/review/run_multi.go`): N-agent orchestrator. Each agent runs concurrently in its own goroutine; events fan into a single dispatch loop so the serial-dispatch contract is preserved. Per-agent skills/prompts are injected via `perAgentConfiguredReviewer` adapter (each reviewer sees its own `RunConfig` despite the shared API surface). +- **Env-var contract** (`cmd/trace/cli/review/env.go`): single source of truth for `ENTIRE_REVIEW_*` constants used by spawn-side and lifecycle adoption. +- **Scope detection** (`cmd/trace/cli/review/scope.go`): `detectScopeBaseRef` returns the first existing ref from the fallback chain `origin/HEAD → origin/main → origin/master → main → master`. Overridable per-invocation via `--base <ref>` (validated through go-git's `ResolveRevision`). Banner output: "Reviewing feat/X vs main: 3 commits, 7 files changed, 2 uncommitted". + +## Multi-Agent UI + +When `RunMulti` is dispatched in a TTY, the sink slice is `[TUISink, DumpSink, SynthesisSink?]`: + +- **`TUISink` / `reviewTUIModel`** (`cmd/trace/cli/review/tui_sink.go`, `tui_model.go`, `tui_detail.go`): live dashboard with one row per agent (name, status, tokens, last assistant preview, duration). `Ctrl+O` enters drill-in mode on the alt screen showing the full event buffer for the selected agent; `Esc` returns to the dashboard. `Ctrl+C` cancels the run via the shared `CancelFunc`. The model uses `tea.WithoutSignalHandler` so the cobra root retains SIGINT routing. After all agents finish, the user dismisses with any key — `RunFinished` blocks on dismissal so `DumpSink` renders below the TUI rather than overlapping it. +- **`SynthesisSink`** (`cmd/trace/cli/review/synthesis_sink.go`): opt-in y/N prompt offered after the dump. On "y", composes a synthesis prompt covering all agent narratives + per-run user prompt, calls the configured summary provider, and prints the unified verdict. Skipped silently when stdin can't prompt, the run was cancelled, or fewer than 2 agents produced usable output. Provider failures degrade gracefully ("synthesis unavailable: <err>") so the user can still commit. +- **Sink composition** (`composeMultiAgentSinks` in `cmd/trace/cli/review/cmd.go`): pure helper taking explicit `isTTY`/`canPrompt` so tests don't depend on real TTY detection. `findTUISink` picks the TUI out of the slice for `Start`/`Wait` lifecycle hooks. + +## Skill Discovery (Claude Code) + +`DiscoverReviewSkills` (`cmd/trace/cli/agent/claudecode/discovery.go`) walks three roots: plugin cache (`~/.claude/plugins/cache/<market>/<plugin>/<version>/{skills,commands,agents}`), user skills (`~/.claude/skills`), user commands/agents (`~/.claude/commands`, `~/.claude/agents`). + +For the plugin cache, `pickLatestVersion` picks ONE version directory per plugin: highest valid semver wins; if no entries parse as semver, the lexicographic max is picked (handles the `unknown` sentinel some plugins ship).

Explain the architecture you want first, based on your own understanding, or have the agent explore the code and propose approaches before any edits happen. If the first implementation doesn't look right, just start over and use what you learned to do better next time. Re-rolling is cheaper than untangling. +- **Spot the laziness:** LLMs will make their own job easy. They write trivial tests, make types wide and optional so the compiler doesn't complain, catch exceptions and log instead of handling errors, and copy local patterns whether or not they fit. When you notice this happening, push back and ask the agent to do the work properly. +- **Spot the uncertainty:** As much as the bots declare "I see the issue now clearly," they often don't. Call them on it if you see the agent flailing. Another telltale sign: the agent starts listing the many ways it fixed an issue, or starts writing overly defensive code. +- **Spot the bloat:** Agents like to insert redundant comments, or worse, comments that describe the change at hand rather than the resulting code. They write loads of tests that don't really test anything, and when they do, they test the implementation rather than the intention. They also like to log anything, just in case.
