From 8387723671f9ef869bbf308866804cce5b786ee5 Mon Sep 17 00:00:00 2001 From: xopham Date: Thu, 21 May 2026 11:56:45 +0200 Subject: [PATCH 1/3] [SOURCE-193] Add Claude PR review workflow Brings the read-only Claude review pipeline over from the sandbox repo (DataDog/docs-actions-sandbox-xopham). Comment `/review` on a PR to trigger Claude to produce a JSON review payload that the post job sanitizes and submits via the GitHub API. Three-job security model: - gate (contents: read, pull-requests: read): verifies the commenter has repo write access via the collaborators/.../permission API and resolves head_sha/base_sha once. - review (contents: read, pull-requests: read): runs Claude with --allowedTools "Read,Glob,Grep" only and no write capability on GitHub. The PR head lives in __untrusted/, the pinned PR diff in __untrusted_diff/, and the trusted scripts/schemas/style guide are sparse-checked out from the default branch. - post (contents: read, pull-requests: write): re-validates the JSON against .github/schemas/create-review.json (Ajv with SHA-512 pinned via npm ci), re-scans for GitHub/Anthropic token patterns, and submits a single review through pulls.createReview. Requires the CLAUDE_API_KEY repo secret. Falls back to a failure-shape review comment with a workflow-run link if anything fails.

The pipeline has three jobs: `gate` (verify the /review caller +# has repo write access and resolve the PR head SHA), `review` +# (run Claude with read-only tools and produce a JSON review +# artifact), and `post` (sanitize and submit the review via the +# GitHub API). Treat the checked-out tree and PR/comment +# metadata as hostile input subject to prompt injection. +# +# 2. Permissions are scoped per job: +# gate: contents: read, pull-requests: read +# review: contents: read, pull-requests: read (no write) +# post: contents: read, pull-requests: write +# Claude runs in `review`, which has no write capability on +# GitHub. Only `post` writes, and it never runs Claude. +# +# 3. Do NOT add any other secrets (API keys, tokens, etc.) to the +# review job via `env:`, `with:`, or `secrets.*`. A prompt- +# injected Claude can exfiltrate anything that reaches this job. +# The only secret that belongs here is the Anthropic API key, +# and it must stay scrubbed from Claude's subprocess env (see +# CLAUDE_CODE_SUBPROCESS_ENV_SCRUB below). +# +# 4. Do NOT use dd-octo-sts or any other token broker. Those mint +# elevated GitHub credentials; if Claude sees them (directly or +# via /proc) it can bypass the read-only constraint. Stick with +# the workflow GITHUB_TOKEN. Beyond the read-only constraint, +# the workflow GITHUB_TOKEN is explicitly *unable* to create or +# approve pull requests — GitHub blocks both to prevent workflow +# recursion. Even if a prompt-injected Claude somehow obtained +# this token, it could not open a malicious PR against this +# repository or self-approve one. A broker token does not have +# that built-in safety. +# +# 5. The review job runs the Claude Code action in *agent* mode +# (triggered by the `prompt:` input — no `trigger_phrase` and +# no `track_progress`). Tag mode auto-appends `Bash(git add| +# commit|rm:*)` + the git-push wrapper to `--allowedTools` and +# forces `--permission-mode acceptEdits`. Agent mode does +# neither. Do NOT add `track_progress: true` or +# `trigger_phrase:` without redoing the tool-surface analysis. +# +# 6. Claude's tool surface is `Read, Glob, Grep` only. No MCP +# write tools (no inline-comment server), no `Bash`, no `Edit`, +# no `Write`, no `MultiEdit`, no `NotebookEdit`. Claude's only +# output channel is its final stdout message, which the +# workflow parses as JSON. Re-introducing any write-capable +# tool collapses the separation between content generation +# (review job) and posting (post job). +# +# 6a. Trust boundary in the review job: the workspace root is the +# *default branch* (trusted), sparse-checked-out to just +# `.github/scripts/`, `.github/schemas/`, and `.claude/`. The +# PR head is checked out into `./__untrusted/` and the +# rendered PR diff into `./__untrusted_diff/`. The +# `github-script` step `require()`s only from +# `${GITHUB_WORKSPACE}/.github/scripts/...`, which resolves to +# the default-branch versions of those scripts — so even if a +# PR modifies `validate_review.js` or `scan_secrets.js` the +# trusted versions still run. `.claude/pr-review.md` is also +# read from the trusted side so the PR cannot rewrite its own +# review instructions. Do NOT change the layout so that +# `require()` or the prompt-file read resolves into +# `__untrusted/`. +# +# 7. The post job sanitizes the JSON twice — once in `review` +# before artifact upload, once in `post` after download — using +# the same secret-pattern regex list (GitHub and Anthropic +# token formats). Any match aborts the review and posts a +# failure notice through the same channel. Do NOT relax the +# sanitizer or skip either pass. +# +# 8. Do NOT replace `allowed_non_write_users` with `*` or a real +# username. It is a sentinel; see the comment on that input. +# +# 9. Do NOT switch the checkout to `pull_request_target` semantics +# or remove `persist-credentials: false`. PR head contents are +# untrusted; leaving the workflow token in `.git/config` would +# let any shelled-out git command authenticate as the workflow. +# +# 10. The `gate` job is the trigger boundary: it verifies the +# commenter has repo write access via the `collaborators/.../ +# permission` API (authoritative, repo-scoped — `MEMBER`-level +# `author_association` is org-wide and would over-grant).

Narrow `.claude/` sparse-checkout to just `pr-review.md`. The repo's `.claude/settings.json` enables Claude Code plugins from external marketplaces, which can register hooks, MCP servers, and agents that would expand the review job's tool surface beyond Read,Glob,Grep. 2. Lock the read-only tool surface from four angles in `claude_args`: `--tools "Read,Glob,Grep"` (restricts available set), `--allowedTools "Read,Glob,Grep"` (auto-approves them), `--permission-mode dontAsk` (blocks permission prompts), `--disallowedTools "Bash,Edit,Write,MultiEdit,NotebookEdit"` (explicit denial). `--allowedTools` alone only pre-approves; the additional flags make the restriction explicit and survive future Claude Code default changes. 3. Constrain `side` and `start_side` to LEFT/RIGHT in the review schema. Upstream publishes them as plain strings with an example, but the runtime API rejects any other value and fails the whole review. The enum catches typos like `right` at the schema layer. 4. Add CODEOWNERS entries giving @DataDog/sdlc-security sole ownership of the workflow, scripts, and schema. `.claude/pr-review.md` stays on the default ownership since it is review instructions, not part of the security boundary.
