Other refs/events fail closed. + +Same-repository PRs include bot and Dependabot authors. Automatic fork events +only update the sticky comment with approval instructions; they never run +inference. A maintainer explicitly dispatches the caller with `pr-number` and +`approved-head-sha`. The triggering actor must currently have write, maintain, +or admin permission. Approval does not carry forward to a new head. + +Reviews use a repository/PR concurrency group and cancel superseded runs. A +cancelled run may leave the SHA-attributed, nonfinal pending comment behind; +cleanup is not guaranteed. + +## Review boundary + +The workflow captures exact open-PR base/head SHAs, checks out the head with full +history and no persisted credentials, submodules, or LFS, then computes one +`base...head` Git diff with external diff and text conversion disabled. There +is no alternate source route. Sensitive-named paths, binary/submodule/LFS +changes, missing objects, and diffs over **100000 bytes** produce incomplete +results without inference. Unchanged sensitive paths remain excluded from the +agent's read rules; these naming exclusions are not a general secret scanner. + +OpenCode runs outside the PR checkout with fresh home/XDG directories and +trusted V2 configuration. PR plugins and configuration are not loaded as +runtime configuration. Only trusted reviewer prompt bodies and five selected +skill Markdown files are imported from `charts` commit +`09a08579a2b0023044875b131477dd05b0e638fc`; production configuration, MCP +servers, provider settings, and primary-agent instructions are not imported. + +The primary can delegate to `adversarial-code-reviewer`, +`infra-security-reviewer`, `devops-engineer`, `qa-engineer`, and +`release-engineer`. Every agent has independent deny-by-default permissions; +children cannot delegate. Source reading and named trusted skills are narrowly +allowed, but shell, mutation, Code Mode, web, and MCP tools are not. +`devops-engineer` remains tool-free. All reviewers use the selected model. +Missing required evidence or blocked reviewers must be reported, not invented. + +## Results and dependencies + +The CLI has 15 minutes within a 20-minute job, with no retry or provider-failover +wrapper. Exact base/head freshness is checked before inference and before final +publication. The maintained sticky-comment action updates one `opencode-review` +comment. Its write is not atomic with the freshness check; every result is +explicitly attributed to its reviewed SHAs rather than claimed current forever. + +Only the final assistant text is extracted from the pinned CLI's NDJSON stream. +Reasoning, tool output, stderr, and provider errors are not published. Findings +are rendered as inert indented text, preventing model-generated images, links, +or mentions from becoming active comment markup. The final model line must be +exactly `REVIEW_COMPLETE` or `REVIEW_INCOMPLETE`; missing/invalid/oversized output +is incomplete, not silently truncated. Completion does not mean no defects. + +This path selects official npm `@opencode/cli@2.1.4`, Node 24, checkout 7.0.1, +setup-node 7.1.0, github-script 9.0.0, and sticky-pull-request-comment 3.0.5. +Actions use full commit pins in the workflow. The GitHub latest-release selector +currently reports OpenCode V1; it must not select the V2 CLI dependency. + +## Validation and activation gates + +`.github/workflows/_opencode-review-tests.yml` runs +`tests/test_opencode_review_workflow.py` with PyYAML 6.0.3 and Node mocks against +the actual inline scripts. It uses no provider secret or inference. Existing +repository lint remains unchanged. These tests cover control flow, generated +configuration, collection bounds, stale snapshots, and stream decoding; they +do not prove runtime permission enforcement, real event/secret behavior, +cancellation, CLI compatibility, or review usefulness. + +Before activation: resolve completed-diff/security reviews and PR CI; select the +reviewed shared commit in the separately reviewed `tfroot-github` caller; +confirm its plan and any apply/adoption; provision the provider secret securely; +confirm explicit repository enablement; and authorize a bounded functional +pilot including malicious configuration and denied-tool probes.
