The SKILL.md `scriptPath` fallback is removed. +2. **`prepare_review` (mod code):** + - `$.process.run`: git rev-parse (HEAD, toplevel, branch, branch merge + config, status), `git fetch origin refs/heads/`, merge-base, + `rev-list --count HEAD..FETCH_HEAD`, `diff --name-status/--numstat/--shortstat`. + - `$.mcp.call('plugin:github:github', …)`: resolve PR (branch config → head + filter → SHA scan, as SKILL.md does today), `pull_request_read get`, + `get_me`, `get_review_comments` (paginated), `get_reviews` (paginated). + - Checks (ported from SKILL.md): head SHA matches, PR open, origin is the + base repo, `base.ref` matches `^[A-Za-z0-9._/-]+$`. + - Follow-up detection (ported from `review-pr.js` 1181-1230: my threads, last + substantive review, reviewed commit) and follow-up delta computed with git + (`merge-base --is-ancestor`, `rev-list --count`, `diff -U0` hunks), replacing + the verifier's git work (1254-1257). + - Lens selection: `$.model.complete` (Sonnet) over the file list/numstat and + the lens roster's `runsWhen`; validate JSON; always include code-reviewer; + fall back to all lenses on failure (as today) *(probed: 5.1 s, valid)*. + - Writes everything to `$.state` (`review.run`), opens the pane in a + progress view, returns the handle. +3. **Launch hook:** narrow `tool.call` on the review workflow name. If + `review.run` is missing, stale (handle or HEAD differs), or a run is in + flight, answer `{ deny: }`. Otherwise generate a run nonce and + rewrite `args` to the full launch payload: + `{ run, pr: {owner, repo, number, title, body, author, baseRef, headSha}, + checkoutPath, mergeBase, lenses: [{ name, effort }], followUp: + { threads, reviewSummaries, reviewedCommit, delta } | null }`. + Record `taskId`. *(rewrite probed)* +4. **Lens prompts stay in the workflow; the mod keeps a small selection + roster.** `review-pr.js` keeps `REVIEWER_PROMPTS`, `STANDARDIZATION_SUFFIX`, + checkout instructions and the follow-up verifier prompt, and looks up each + prompt by the lens name in `args.lenses`. The mod holds a duplicated roster + of `{ name, runsWhen, effort }` (~20 lines) for lens selection. Drift guard: + the workflow fails fast on a lens name it does not know (listing it), and a + mod test pins the roster's names to the workflow's eight `REVIEWERS` keys. +5. **Fan-out (`review-pr.js`):** validate `args` (fail fast if `run`/`lenses` + missing — mod not loaded), then `parallel()` one `agent()` per lens plus the + follow-up verifier when `args.followUp` is set, all with agentType + `pr-review-toolkit:pr-review-analysis-readonly`. Every prompt interpolates + the run nonce and lens name and ends with: report by calling the deposit + tool with `run: ""`; if it answers `rejected`, fix what it names and + call again; then return `{ submitted: true }`. Agents return that small + schema to the workflow. Delete from `review-pr.js`: THREAD/SELECTOR/ + SYNTHESIS/FOLLOW_UP schemas, collector/selector/synthesis `agent()` calls, + follow-up detection, the verifier's git delta steps, and `finalizeBoard` and + helpers (645-920). Keep the lens prompts, `REVIEWERS` (prompt + effort; its + `runsWhen` moves to the mod's roster), suffix, checkout instructions and the + verifier prompt (now judging only, with the delta passed in). *(deposit from + workflow agents probed: 2 agents, 10 s)* +6. **Deposit tools (mod):** + - `submit_findings({ run, lens, findings, positiveObservations })` — + validated against `FINDING_SCHEMA` (review-pr.js 14-51). + - `submit_followup({ run, items })` — validated against the verifier item + shape (ask, status, evidence, fixedIn?, threadId?). + - Correlate by `run` nonce (agentId informational). Unknown nonce → + `rejected: unknown run`. A later valid submission for the same lens + replaces the earlier one. Answers: `accepted` or + `rejected: . Resubmit.` +7. **Lens agents:** `pr-review-analysis-readonly` with + `mcp__pr-review-toolkit__submit_findings` and `…__submit_followup` added to + its `tools`.

Pane states: + `progress → board → drafting → preview → posting → done`, plus `failed`. + Board actions: select, promote/demote, too picky, details, ask Claude. +12. **Drafting:** "Draft" calls `$.prompt.submit` (not awaited while Claude is + busy) with the selected items as JSON (finding fields, + `existingReviewOverlap.commentId`, `followUpItemId`, follow-up items) and an + instruction to Read `references/drafting.md` (posting.md's drafting rules, + kept) and call `set_drafts`. `set_drafts({ drafts: [{ id, kind: + 'line'|'reply'|'body', path?, line?, commentId?, body }] })`. The review + event (Comment / Request changes / Approve) is chosen in the pane. + Rewording: pane instruction field (`Input` is single-line) or chat → Claude + calls `set_drafts` again. +13. **Preview + posting:** frozen exact preview; "Post this review" is the sole + approval. Mod validates anchors against the diff hunks, re-reads the PR head + (blocks if moved), then posts with `$.mcp.call`: replies via + `add_reply_to_pull_request_comment`; line comments via + `pull_request_review_write create` (pending) → `add_comment_to_pending_review` + → `submit_pending` with event and body; body-only via `create` with event. + Logs what it posted; failures return to Preview; `delete_pending` on abandon. + *(probed on cblecker/dp-check#50: pending create → comment → out-of-diff + comment `isError` → `delete_pending` → nothing left)* +14. **Cancel/cleanup:** pane cancel → `TaskStop` with the workflow `taskId` + *(re-verify for workflows)*; `session.end` (`/clear`, `/resume`) → + fire-and-forget `TaskStop`, then reset `review.run` (1.5 s budget for all + `session.end` hooks). + +## Trade-offs accepted + +- One short Claude turn to launch the Workflow and one when it completes. +- `$.model.complete` has no schema enforcement; JSON validated and retried in code. +- Lens selection loses the selector agent's ability to read individual patches. +- No automatic retry of a failed lens in v1 (matches today: reported as reduced + coverage). + +## Open items for the spec + +- Re-verify: rewriting the idle-path completion `prompt.submit`; `TaskStop` on a + workflow `taskId`. +- Per-lens timeout: none in v1 beyond Workflow's own handling, or a + run-level timeout (~15 min) that calls `TaskStop`. +- Pane layout per state: study the built-in `diff` mod (scrolling, focus, + keybinding-backed buttons, width rules, `/clear` handling). +- Packaging (major bump to 3.0.0): `hooks/hooks.json` + TS modules + (prepare, collect, followup, select, launch, deposit, bash-guard, completion, + synthesis, board, pane, drafting, posting, roster), `types/index.d.ts`; + SKILL.md reduced to the glue in step 1 (its `allowed-tools` to the two calls); + delete `references/board.md`; rename posting.md's drafting rules to + `references/drafting.md` and drop its preview/approval/posting sections; + delete agents `pr-review-github-collector`, `pr-review-selector`, + `pr-review-synthesis`; add the deposit tools to + `pr-review-analysis-readonly`; `.skillsaw.yaml` allowlist cleanup (the six + review-pr `!` lines); README (state Claude Code ≥ 2.1.287 — no manifest + field exists for it) and CLAUDE.md. +- Testing: `claude plugin test` for roster/`REVIEWERS` name parity, routing/board, deposit validation, Bash + command parser, launch-hook deny cases, completion rewrite, synthesis + validation, posting sequence (stubbed `$.mcp`, `$.process`, `$.model`, + `$.tool`); end-to-end on a real PR (first review and follow-up). + +## Limitation if ever shared + +Managed/Team/Enterprise setups load the built-in `sec-default` guard, which +refuses a user-installed mod's `tool.register` while managed settings set +`allowedMcpServers` (breaks the deposit tools, `prepare_review`, `set_drafts`), +and `allowManagedModsOnly` refuses the whole mod. + +## Cleanup + +Throwaway probe mod `review-pr-probe` in +`/Users/cblecker/.config/claude-code-personal/dev-mods/4eb5638e-cd6d-4dfa-a5f6-ec7f91c0e6c3/` +and scratchpad/tmp leftovers: user deletes (the Bash sandbox can't). + +--- +--- + +# review-pr Workflow + Mod Implementation Plan + +**Execution method (user choice): subagent-driven** — use +superpowers:subagent-driven-development; a fresh implementer and a fresh +reviewer per task, whole-branch review at the end.

A second `/review-pr` while a run is in flight, or after HEAD moved — launch + hook must deny with a reason, not clobber the run (Task 7 tests). +4. The model returns JSON wrapped in prose or code fences, or invalid JSON — + selection falls back to all lenses; synthesis retries once then lists + findings unmerged (Tasks 4, 11 tests). +5.

for lens agents During an active review run, a subagent's Bash call is auto-allowed when Claude Code would otherwise ask and the command is read-only git (optionally piped through head or tail). The guard parses the command into the words the shell would produce and refuses anything it cannot fully account for, including git --output, a lone background &, quote or escape tricks, expansions and globs.

14/42] fix(pr-review-toolkit): reject truncated delta diffs The host cuts process stdout at 4 MiB, so a cut diff came back as available with a partial file list, and files missing from it read as unchanged. ProcResult now carries truncated, and computeDelta reports the delta unavailable when the diff was cut. Also share one SHA_RE, drop the stale mergeBase comment, reuse the Delta file type, and state what the delta still reads as unchanged.

It refuses while a launched run is in progress and stores the prepared run. The Workflow launch hook gates review-pr-analysis on a fresh preparation for the same PR and HEAD, claims it atomically with a run nonce before the workflow starts, records the taskId, and gives the nonce back when the launch does not start. It rewrites args to the full launch payload. PrMeta gains baseRepo from base.repo.full_name for the origin check.

The read-only lens agent gains the two deposit tools and a Reporting section.

From 16edcd18d045985e967e6d14a845f88e27d7911a Mon Sep 17 00:00:00 2001 From: Christoph Blecker Date: Fri, 2 Oct 2026 17:55:01 -0700 Subject: [PATCH 18/42] feat(pr-review-toolkit): rewrite workflow completion notices Recognise the review workflow's completion notice for the recorded taskId on both delivery paths (queued_command attachment, idle task-notification submit), rewrite it to one line so no workflow result enters the transcript, and advance the run: a completed notice marks the run synthesizing and finishes it detached; any other status fails it. Only the first notice for a run in progress advances it.

Failures stop and name what posted; a failed line comment or submit deletes the pending review. Also: prepare_review refuses while a review is posting, and the Task 14 drafting fixes (non-retry rejections, per-item reply targets, cleaner stored drafts, drafting.md merge wording).

Cancel is refused while posting. session.end stops the workflow of a run in progress, resets the run and passes the end on. session.start ends a run found posting as done with "Posting was interrupted; check the PR." A post whose outcome cannot be written now ends the run the same way instead of staying in posting. Deposits are accepted only while the run is in progress. A workflow launch that returns after a cancel no longer revives the run and is stopped, and a preparation cancelled before it launched cannot launch.

Describe the lens agents' auto-allowed read-only git and the GitHub tools the mod calls. Add a "Mod hybrid (3.0.0)" section to DESIGN_NOTES with the platform facts and the reasoning, including the same-file `$` rule and the injected Io. Mark the 2.x sections that 3.0 moved into the mod, and drop the references to the deleted collector, selector and synthesis agents, board.md, posting.md and the scriptPath fallback. Update the repo CLAUDE.md architecture line and the top-level README plugin entry, and demote the second H1 in the implementation plan so markdownlint passes (MD025).

The launch carries a small `args` payload: the PR -metadata subset, the checkout path, the pinned `merge_base`, and your GitHub -login. No bulk data rides `args` — workflow agents gather their own diff -context from the checkout. The workflow: - -- collects existing review threads and submitted reviews through GitHub MCP - read tools (collector agent) in parallel with a **selector** agent that - reads the changed-file list over the pinned range (`git diff --shortstat`, - `--name-status`, `--numstat`, and per-file patches only where needed) and - returns which lenses should run, a one-line rationale each, and the PR's - shape -- falls back to running **all** lenses when selector output fails validation - — selection is disclosed in `reviewMeta.lensSelection`, never silent -- detects a **follow-up review** when threads or reviews by your login exist - on a PR you did not open, and records the commit you last reviewed +itself from the installed plugin. A mod cannot start a workflow, so Claude does, +and the mod's launch hook rewrites the call's `args`: the PR metadata subset, +the checkout path, the pinned `merge_base`, the lens list with each lens's +effort, the follow-up context, and a run nonce. The hook launches only from a +fresh preparation and denies, with the reason, when the preparation was already +used, a run is in flight, `HEAD` moved since it was prepared, or you cancelled +it. No bulk data rides `args`: agents gather their own diff context from the +checkout. The workflow: + - fans out the selected specialists in parallel; each reads the checkout directly — read-only `git diff` over `..HEAD` for patches, Read/Grep/Glob for contents, and `git log`/`blame`/`show` only when a finding depends on history — so findings carry PR head line numbers by - construction. In a follow-up review a **verifier** agent joins the fan-out, - checks each of your earlier asks against the head, and reports what - changed since your review -- synthesizes a review board: the synthesis agent returns only decisions — - which findings share a concern, each group's section, and which existing - thread it overlaps — and the workflow builds the board items from the - specialists' own text and the collector's thread records - -The workflow does not draft or post comments. Drafting happens in the skill -conversation after the user selects findings. Posting requires an exact -preview and explicit final approval. - -The control flow is: - -```text -skill command (in a PR head checkout) - |-- resolve PR, verify HEAD == PR head, fetch base, pin merge_base - v -Workflow(pr-review-toolkit:review-pr-analysis) -> workflow agent() calls - collector -> pr-review-github-collector -> GitHub MCP reads (threads, reviews) - selector -> pr-review-selector -> read-only git over the pinned range - specialists-> pr-review-analysis-readonly -> read-only repo/git inspection (no MCP) - verifier -> pr-review-analysis-readonly -> your earlier asks vs the head (follow-up only) - synthesis -> pr-review-synthesis -> no tools; prompt JSON only -``` - -Name-mode invocation exists for compatibility with Claude Code's Workflow -hardening: since 2.1.251, a `scriptPath` outside the session's readable set -(working directory, added directories) is rejected by design — "scriptPath -must be a script path this tool returned, or a file you can already read" — -and the plugin cache is outside that set.
