Unsupported channel or + permission states fail explicitly and never run in the parent channel. +- `/study tasks [scope] [state]` + - `scope` is `mine` by default or `channel`; `state` is `all`, `active`, or `terminal`. + - The ephemeral result lists at most ten recent visible tasks and links to their card + or source message. +- `/study status ` + - Autocomplete offers recent tasks visible to the caller. + - The ephemeral result shows persisted state, the same safe failure/next-action detail + as the card, and caller-authorized actions even if the card is unavailable. + - Autocomplete is not authorization: manually supplied IDs undergo the same-guild + and current channel-visibility checks. + - The owner can confirm forgetting an inactive record. This removes local metadata, + not Discord messages or the underlying Codex session. + +Commands are guild-only. With `DISCORD_GUILD_ID`, declarations are copied and synced to +that development guild; otherwise they sync globally. Startup stops clearing the tree. +`DISCORD_GUILD_ID` remains a sync target, not a new allowlist. All intake and component +paths require normal guild membership and channel access and otherwise preserve the +deployment's current guild reach. + +### Message context action + +`Ask StudyOS about this` opens an instruction modal. The selected message, bounded +attachments, author, channel context, and jump URL become typed source context. The task +runs in that message's channel/thread without creating another thread. + +### Canonical task card + +Every task creates one persistent Components V2 card, updated in place with: + +- short task ID, requester, relative start time, and state; +- bounded plan and safe high-level activity, never raw commands or reasoning; +- source/result links when available; +- controls valid for the public state; every callback separately authorizes its caller. + +While running, the card offers **Stop task** and, only if the runtime supports steering, +**Add context**. Add context opens a modal and calls the existing steer path for the +exact active turn. `NO_ACTIVE_TURN` or `NOT_STEERABLE` produces an ephemeral explanation +and never claims the input was queued. + +On success, normal result/artifact delivery remains and the card offers **View result** +and, only when the runtime can resume the session, **Continue**. Continue opens an +instruction modal only for the latest task in that channel/thread because the Codex +conversation is channel-keyed, not task-keyed. It creates a linked task/card on the same +session/worktree while preserving the old result. Older cards explain that a new task or +dedicated thread is required. + +On failure, the card is rebuilt without the obsolete **Stop task** action. It shows a +specific safe category and consequence, for example: + +- `Timed out after 30 minutes. Partial work and the agent session were kept.` +- `Codex app server disconnected. The session and worktree were kept.` +- `Agent process exited before returning a result.` +- `Agent finished, but Discord could not deliver the result.` + +**Why it failed** returns requester-only detail: category, safe explanation, whether +partial work is preserved, whether retry is safe, and the task ID for log lookup. It +never exposes traceback, raw stderr, command output, prompts, tokens, or host paths. + +**Retry** is shown only for a capability selected by `AgentGateway`: + +- `continue_session` starts a new turn in the persisted session/worktree, instructing + the agent to inspect existing work and finish without repeating completed work; +- `retry_delivery` reposts a bounded in-memory `PreparedDiscordReply` without the agent, + but only after a definitive pre-send/non-delivery error; +- `none` hides Retry and explains the required corrective action. + +Timeouts and recoverable app-server exits use `continue_session` only if the gateway +confirms a persisted session and no still-active turn. Configuration, invalid output, +unsafe one-shot, unknown non-resumable failures, and ambiguous Discord network outcomes +use `none`. A delivery failure must never rerun the agent because that could duplicate +commits, PRs, comments, or other effects; ambiguous delivery tells the user to check the +channel first. + +## Architecture + +### Typed intake and task service + +Adapters construct a transport-neutral `DiscordTaskRequest` with source kind, guild, +execution channel/thread, actor and trigger-event IDs, optional source-message ID, +prompt, validated attachment paths/context, and optional thread request. Adapters +validate, acknowledge, and delegate; they never call `AgentGateway` directly. + +`DiscordTaskService` owns `start`, `steer`, `stop`, `retry`, `continue_task`, lookup, +authorization, atomic state transitions, failure classification, retry selection, and +card coordination. `DiscordMentionCoordinator` becomes a thin adapter; commands, +context action, and dynamic components use the same service. Existing `AgentGateway` +ask/steer/interrupt, session store, attachment validation, worktree selection, and reply +preparation remain the execution boundaries. + +Only a finalized `PreparedDiscordReply` is cached, with at most ten files and the existing +per-file size limit. Paths are revalidated as existing and inside allowed artifact roots +before Retry; generated files remain owned by the cache and are deleted on success, +downgrade, or shutdown. Partial or ambiguous sends are never cached for Retry. New +focused modules hold task values/transitions, store, authorization, service, commands, +and cards without duplicating invocation or reply preparation. + +### Codex app-server contract + +The persistent Codex app-server path is the primary runtime. When channel sessions are +enabled and `AGENT_COMMAND` resolves to Codex: + +- startup completes app-server `initialize` before Discord accepts tasks; initial + initialization/protocol mismatch is readiness-fatal, so the bot does not log in; +- start uses `thread/start` or `thread/resume`, followed by `turn/start`; +- Add context uses `turn/steer` with the exact active turn ID; +- Stop uses `turn/interrupt`; +- Retry/Continue starts another turn on the same Codex thread and channel/thread + worktree, never a silent replacement session; +- existing lifecycle, plan, command, file, tool, commentary, completion, and token + notifications continue driving the public progress summary and usage records. + +A required execution channel key—not optional `source_message_id`—selects app-server and +worktree routing. `source_message_id` is context only; slash, Retry, and Continue turns +therefore cannot fall through to one-shot execution. Reply preparation uses the task ID +as its delivery-file key when no source message exists. + +A process exit atomically marks the runtime unavailable, unsubscribes the dead client, +clears its started state, and fails every concurrent active turn as +`runtime_disconnected`. The next start/Retry enters one single-flight recovery: close the +stale transport, create and initialize a new client, resubscribe, then start or resume the +stored channel thread. A disconnected Retry starts no new attempt until reconnect and +resume succeed; it first claims `recovering`, returns to failed if recovery fails, and +never runs a one-shot command. + +A dedicated Discord thread ID becomes the existing app-server session/worktree key. +Other runners support start and final delivery, but controls requiring steer/resume are +omitted. Initialization or protocol mismatch becomes `runtime_incompatible`; it never +falls back to one-shot execution. After login this is a typed task failure; initial +startup incompatibility remains readiness-fatal as defined above. + +`Dockerfile.agent`'s pinned Codex version is the contract. Implementation generates the +protocol schema from that exact binary and runs a real stdio smoke in the built image. +Host CLI behavior from a different version is not proof of compatibility. + +### Durable task model + +Each record stores a UUID plus short display prefix, owner/guild/origin/execution IDs, +source/card/result message IDs, neutral source label, optional continuation links, +timestamps, attempt, state, optional interruption cause, and—on failure—typed category, +safe summary, and retry mode. It stores no prompt, output, raw error, credential, or +attachment content. + +States and allowed transitions are: + +- `failed | timed_out | interrupted -> recovering` via resumable Retry; +- `recovering -> starting | failed | stopping`; +- `starting -> running | failed | stopping`; +- `running -> delivering | failed | timed_out | stopping | interrupted`; +- `stopping -> stopped | failed | interrupted`; +- `delivering -> completed | delivery_failed`; +- `delivery_failed -> delivering` via in-memory delivery Retry; +- latest-channel Continue atomically links a new `starting` child task while leaving the + completed parent unchanged. +- startup reconciliation allows `recovering | starting | running | stopping -> interrupted` and + `delivering -> delivery_failed` without invoking the agent. + +Each callback claims its Discord interaction ID in a bounded deduplication set. A +state-changing action then performs an atomic compare-and-set; a Retry increments +`attempt`, while Continue atomically links exactly one child. Locks cover state/store +work only and are released before Discord or agent I/O, so duplicate clicks cannot start +the same operation twice or serialize other channels. + +Stop, timeout, runtime exit, and restart atomically claim `user_stop`, `timeout`, +`runtime_exit`, or `gateway_restart` before interrupt/cleanup. A previously recorded +`delivering`/`completed` result wins; otherwise the first cause claim wins and later +signals cannot rewrite it. + +The store follows the existing JSON pattern at +`$CODEX_HOME/gateway/discord-tasks.json`, writes by atomic replace with owner-only mode, +and retains inactive records for 30 days up to 500, never pruning active records. + +On startup the reconciliation transitions above are applied. `delivering` becomes +`delivery_failed` with retry mode `none`, and existing delivery Retry also becomes `none`, +because the cache is gone and delivery cannot be proven. Every affected reachable card +is fetched and rerendered; a deleted/inaccessible card leaves the store authoritative and +rendering fails best-effort. Dynamic handlers resolve stored IDs, so only capabilities +surviving restart remain actionable. + +## Concurrency, Authorization, And Privacy + +- One active task per execution channel/thread preserves runtime/worktree isolation. +- A dedicated thread gets its own channel-keyed session and worktree. Busy starts link + to the active card. +- Owner checks apply equally to text follow-ups and component actions. A member with + `manage_messages` may Stop for moderation but cannot steer, retry, or continue. +- Every lookup/action validates the current guild and the caller's current `view_channel` + access to the execution/source channel, including owner IDs after access is revoked. +- Public cards/results follow Discord channel visibility. Task lists are ephemeral: + `mine` is owner-only and `channel` includes only visible current-channel records. +- Allowed mentions stay disabled for generated cards and interaction responses. +- Every intake path accepts at most ten attachments of at most 8 MB each. Downloaded + inputs are removed in `finally`; validation failure starts no task. + +## Failure Handling + +- I/O interactions defer within Discord's response window. Interaction validation and + authorization failures are ephemeral; message failures are concise replies. +- Boundary errors map to `timeout`, `runtime_disconnected`, `agent_process_failed`, + `invalid_agent_output`, `runtime_incompatible`, `configuration`, + `workspace_or_attachment`, `discord_delivery`, or `internal`. Unknown exceptions use + `internal`; raw exception strings never enter Discord. +- Every failure says what failed, whether work was kept, and what to do. Retry is present + only when safe and is idempotent across duplicate clicks. +- Missing configuration, command-sync/thread permission failure, and store corruption + are explicit errors with no fallback. +- Missing card delivery does not fail agent execution; final output still uses the + normal reply path. Failed final delivery stays non-completed and retains the card. +- Unknown, stale, expired, or handled component actions explain themselves ephemerally + and never invoke the agent twice. +- Logs include task ID and operation but exclude prompts, tokens, raw errors, and personal + message content. + +## Verification + +Focused tests cover all intake adapters; command sync, autocomplete, modals, deferral, +and thread creation; store round trips, retention, corruption, and restart recovery; +all transitions, compare-and-set races, attempts, and authorization; channel isolation; +dynamic component routing; Add context, Stop, Retry, latest Continue, and stale cards; +safe failure rendering and duplicate Retry suppression; delivery-only Retry; restart +downgrade; forgetting; attachment limits/cleanup; and unchanged mentions, artifacts, +long replies, progress, and worktree routing. They also prove a source-less slash/Continue +uses the channel app-server/worktree and that cross-guild/private-channel IDs are denied. + +Readiness requires `ruff check .`, `pyright`, and `pytest`, plus: + +- a real Discord smoke for guild sync, slash/context modal starts, owner rejection, + optional thread creation, useful failure details, Retry, and restart-visible controls; +- a real authenticated smoke using the pinned `codex app-server` for initialize, + source-less start, progress, steer, interrupt, completion, same-thread Retry/Continue, + and forced child-process death followed by single-flight reinitialize/resume. + +If a safe test guild or authenticated runtime is unavailable, report that verification +as missing; fake-protocol tests are not a substitute. + +## Acceptance Criteria + +1.

That design remains authoritative for +the shared task lifecycle, cards, ownership, recovery, and Discord delivery; this document +governs GitHub webhook intake and GitHub-specific task capabilities. + +## Summary + +GitHub pull requests and issues are passively mirrored into the configured `#pr-review` +channel as native Discord cards. A webhook can create or update a card, but it cannot +invoke the agent, start work, or write to GitHub. + +An authorized user starts work explicitly by clicking Review, Security review, +Vulnerability scan, or Work on this, or by mentioning/replying to the bot with an +instruction in the mirrored item's context. Results stay in Discord by default. External +writes are allowed only when the user's instruction names that exact operation; merge is +never authorized. + +## Goals + +- Make PRs and issues visible where the StudyOS team already coordinates reviews. +- Keep webhook receipt passive, deduplicated, and free of automatic agent side effects. +- Expose four native actions with narrow, obvious capability boundaries. +- Reuse the durable Discord task lifecycle instead of creating a second job system. +- Route execution to the exact validated repository and retain item context across restart. +- Keep results conversational in Discord without silently posting GitHub comments. + +## Non-Goals + +- Automatic review, refinement, implementation, comments, labels, assignments, pushes, + pull requests, issue closure, or any other agent action from a webhook. +- Active probing, exploitation, port scanning, or requests against deployed targets. +- A GitHub dashboard, repository picker, role-management UI, or one command per operation. +- Bot-controlled merge. Merge remains human-only even if an instruction requests it. + +## Native Discord Experience + +### Passive mirror cards + +Verified `pull_request`, `issues`, and relevant `issue_comment` webhooks upsert one +Components V2 card per logical `repository/item-kind/item-number` in +`DISCORD_PR_CHANNEL_ID`, intended to be `#pr-review`. The existing setting now names the +shared PR-and-issue intake channel. + +The card contains bounded repository, number, title, state, author, labels or branch +context when available, and a GitHub link. It does not copy full PR/issue bodies, comments, +reviews, diffs, or logs. Opened, edited, reopened, ready-for-review, synchronized, labeled, +unlabeled, closed, and comment activity updates the existing card when relevant. Comment +events may refresh bounded activity metadata but never copy the comment body. A missing +prior card may be recreated without starting agent work. + +`X-GitHub-Delivery` deduplicates webhook retries. The logical item key prevents new cards +for later events on the same item. Card edits preserve the associated Discord thread and +active task link. + +### Explicit intake actions + +Active cards expose exactly four actions: + +| Action | User input | Capability | +|---|---|---| +| Review | None | Read-only correctness, regression, tests, and maintainability review | +| Security review | None | Read-only auth, secrets, permissions, privacy, trust, and abuse review | +| Vulnerability scan | None | Read-only local SAST and dependency checks against pinned objects already present in the canonical checkout | +| Work on this | Required modal | Implement the submitted instruction in the isolated worktree | + +The first three actions use fixed bounded prompts and start immediately after authorization. +Vulnerability scan cannot probe live hosts or services. Work on this opens a required +instruction modal; an empty submission does not create a task. + +The first accepted action creates or reuses one public item thread beneath the mirror +card. The thread becomes the execution channel, session key, worktree isolation key, and +default result destination. A concurrent action links to the canonical active task instead +of starting duplicate work. A new action is permitted after that task is terminal. + +### Mention and reply intake + +An explicit bot mention in item context, or a reply to the bot's mirror card or item-thread +message, resolves the same typed GitHub item context. The user's text is the instruction +and enters through `DiscordTaskService`; webhook publication remains passive. + +Ordinary conversation in `#pr-review` does not start work merely because it is near a +mirror card. The message must explicitly address or reply to the bot through the existing +mention rules. + +## Authorization And Idempotency + +- The actor must be a current guild member who can view the intake channel. If the item + thread already exists, they must also view it; after first creation, access is verified + before task start. The clicking actor owns the resulting task. +- The bot must be able to view/send in the destination and create, view, and send in the + item thread. Missing permissions fail ephemerally with no parent-channel execution + fallback. +- Component custom IDs contain only the action and an opaque 32-hex mirror ID. They never + contain a repository, item title, URL, user ID, or token. +- The handler claims each Discord interaction ID and compare-and-swaps the mirror revision + before creating a thread or task. Retries and double clicks return the existing result. +- The mirror's active task ID and the task store's one-active-task-per-thread rule provide + a second idempotency boundary across processes and restarts. +- Webhook-delivery and interaction idempotency are independent; receiving an update cannot + reserve or start an action. + +## Architecture + +### Typed webhook and mirror state + +Webhook parsing produces `GitHubMirrorEvent`, never an agent prompt. The passive publisher +renders or edits the card and is not allowed to call `AgentGateway` or +`DiscordTaskService`. + +`GitHubMirrorStore` writes `$CODEX_HOME/gateway/github-mirrors.json` atomically with mode +`0600`. Each record contains an opaque mirror ID, bounded recent delivery IDs and +interaction claims, repository/item identity and URL, bounded display metadata, +guild/channel/card/thread IDs, revision, pending action reservation, and active task ID. +It stores no webhook secret, access token, full body/comment, agent prompt/output, +attachment, or raw exception. + +The controller preallocates a task ID and persists it with the pending action claim before +side effects. Startup reconciliation links a claim whose task exists, or marks an orphaned +claim failed and releases the item for a new interaction. Bounded handled claims make the +same interaction idempotent without retaining modal text or actor identity. + +### Task bridge and execution context + +`GitHubMirrorActionItem` resolves the current record after restart, authorizes and claims +the interaction, creates/reuses the item thread, and passes a typed request to the shared +task service. `GitHubTaskContext` carries mirror ID, repository full name, item kind, +number, URL, and optional validated PR base/head commit IDs. The task record persists only +the opaque mirror reference plus intent. +Retry and Continue re-resolve that reference through the mirror store; a missing record is +an explicit safe failure, never a prompt-parsing fallback. + +The four values of `DiscordTaskIntent` are `review`, `security_review`, +`vulnerability_scan`, and `implementation`; existing tasks use `general`. Validated +`repository_full_name` is carried through `AgentExecutionContext` so worktree routing uses +that exact repository rather than extracting a target from untrusted prompt text. + +Mention/reply resolution looks up a referenced mirror card or item thread in the same +store, then uses the same typed bridge. Dynamic item registration and mirror reconciliation +run once at bot startup alongside ordinary task-card reconciliation. + +### Capability and write boundary + +All GitHub titles, bodies, comments, diffs, and repository content are delimited as +untrusted data, never instructions. Prompt construction is owned by the intent bridge: + +- Review and Security review forbid repository mutation and every external write. +- Vulnerability scan permits safe local static/dependency commands against pinned objects + already present in the canonical checkout, but forbids checkout mutation, cloning, + fetching, repository mutation, active probing, exploitation, and every external write. +- Work on this permits isolated worktree changes requested by the modal instruction. +- A modal or mention/reply may authorize a specific comment, review, label, assignment, + push, PR creation, close, or other external write only when the user's text explicitly + requests that exact operation. Intent, item state, and proximity never imply permission. +- Merge is rejected for every intent and instruction. + +Every task reports its analysis or implementation result in the item thread. No action +automatically posts that result as a GitHub review or comment. + +## Failure, Privacy, And Operations + +- Missing or inaccessible `DISCORD_PR_CHANNEL_ID`, card/thread delivery failure, store + corruption, stale components, and unauthorized actions are explicit safe errors. +- There is no alternate-channel, one-shot-agent, automatic-write, or mock-data fallback. +- Allowed mentions remain disabled for cards and results. Logs use mirror/task IDs and + exclude titles, instructions, personal IDs, URLs with secrets, and raw provider errors. +- Closing or deleting a GitHub item updates card state but never interrupts or starts a + task. Task control remains an explicit Discord action. +- Deployment must remove the obsolete `AGENT_AUTO_REVIEW_ENABLED` control so stale + environment configuration cannot restore webhook-driven work. + +## Verification + +Focused tests cover: + +- PR and issue event rendering, logical-item upsert, delivery deduplication, card edits, + missing-card recreation, and explicit channel failure; +- proof that every webhook action has no agent prompt and never calls agent/task/write + boundaries, including with a stale auto-review environment value; +- restart-safe opaque components, actor/bot authorization, interaction claim and CAS, + item-thread create/reuse, active-task linking, and duplicate-click suppression; +- exact prompts and capabilities for all four actions, Work on this modal validation, + safe scan tooling, and explicit-write/merge denial; +- typed repository routing, opaque task persistence, mention/reply context resolution, + untrusted-content delimiting, and Discord-only default delivery. + +The deployment smoke sends one safe PR event and one safe issue event, repeats a delivery, +and exercises all four actions in the StudyOS test guild. It verifies one card/item, one +thread/item, no webhook-started task, Discord results, and no unrequested GitHub write. + +## Acceptance Criteria + +1. PR and issue webhooks upsert native cards in configured `#pr-review` without invoking + the agent or writing to GitHub. +2. Authorized Review, Security review, Vulnerability scan, and Work on this interactions + create exactly one typed task in the item thread with the documented capability. +3. A bot mention/reply in item context creates an instructed task through the same service. +4. Duplicate deliveries/interactions remain idempotent across restart. +5. Results remain in Discord by default; external writes require an exact explicit user + instruction, Vulnerability scan never actively probes, and no path can merge. diff --git a/pyproject.toml
