Before the agent runs, the action creates a fresh -provisional working comment for the run/attempt and binds it to the native -`update_claude_comment` MCP tool (`CLAUDE_COMMENT_ID`), so the agent passes -only the Markdown body and never chooses a repository, comment, or head -target. The body no longer travels through shell heredocs or `gh api` writes; -the tool keeps its upstream sanitization and secret redaction.

This is a -transport fix, not credential isolation. The preflight binds a fresh slot, and -the publisher still validates the live head and report finality at completion. -After a successful run, CI publishes the report as a NEW -comment carrying a visible reviewed-commit link and CI-owned review-state -metadata (reviewed SHA, base, workflow, run, attempt, summary marker, verdict -mode), then submits a commit-bound request-changes review for blockers or a -neutral comment otherwise, linking directly to the report.

Only after -completion are the previous report (including any pending leftover) and the -consumed working comment collapsed — bodies retained, linked to the new -report — so a failed run leaves the previous report untouched. -Stale, provisional, foreign, or malformed working output cannot be published, and a -push during the run stops publication.

Publication is idempotent per workflow run -and attempt: a repeated finalization reuses the already-published report and never -submits a second formal review, while an intentional new run or attempt gets a new -report. Completed reports are never handed back to the agent as update targets — -every run/attempt writes to its own freshly created provisional working comment, -while completed state is still selected independently for incremental review. -Active findings appear once in their severity section, labeled `New` or -`Prior — still present`. A compact resolved section records fixed/obsolete prior -findings with evidence; it does not repeat the active findings. +The model has a native `--tools` inventory of Read, Glob, Grep and Agent +(the pinned SDK's Task tool), plus the two fixed-target comment MCP tools. +Unlike `--allowedTools`, this limits which built-ins are available: there is +no model shell, interpreter, file-edit tool or general GitHub write endpoint. +The host prefetches the complete PR diff into `.github/pr-review.diff`; +incremental suggestion work still uses the separate filtered compare diff. +Project/local settings and repo-defined MCP servers remain disabled. Audit +subagents inherit the read-only inventory and must return completed native +results before the final result; missing, background or errored audits fail +closed. Source/API contracts support this boundary; a separately authorized +real pinned-runner isolation/output smoke is still needed for runtime proof. + +Before the model runs, CI creates a fresh provisional working comment and binds +it to `update_claude_comment` through `CLAUDE_COMMENT_ID`. That body-only tool and +the fixed-PR inline tool retain upstream sanitization and secret redaction. +Working comments are progress, never final verdict or obligation authority. +The final result is the runner's native `structured_output`: structured blockers, +an exact current-run audit of every frozen prior obligation ID, and `report.summary` +containing the full Markdown in the existing template. CI matches it against +successful terminal metadata and completed Agent/Task results, rejects model +host markers and inconsistent counts, and preserves the pinned sanitizer/redactor +when publishing artifact-backed Markdown. + +Accepted evidence and its frozen snapshot/completion receipts live outside the +PR checkout. A required, immutable `pr-review-result---` +artifact upload precedes publication; it uses the existing repository/organization +retention default, without changing settings. Reports and formal reviews record +the artifact ID and ZIP digest. The seven-day `pr-review-context` upload remains +diagnostics only, including separate reset receipts; it cannot substitute for +failed accepted evidence persistence. + +CI publishes a NEW pending report, submits a commit-bound REQUEST_CHANGES for +structured blockers or COMMENT otherwise (never APPROVE), then marks publication +completed. Only after those operations succeed may it dismiss exact snapshotted +owned blocking reviews. This is default baseline behavior for both profiles, +not a new opt-in. Every original obligation must be affirmatively reverified in +the current completed run—even if an earlier run called it fixed. New blockers, +unverified obligations, missing/expired/corrupt evidence, edited pointers, or +uncertain ownership retain the whole reset. Original accepted artifacts, not +mutable comments or resolved/deleted inline threads, supply the obligations; +superseded reports remain addressable by their original IDs. + +Ownership reuses `(workflow_ref, summary_marker, baseline)` plus exact PR, +review, commit, report, run/attempt and artifact consistency. Formal reviews +must be unedited; report histories must have only visible bot edits. Missing, +deleted or inconsistent API history fails closed. This uses the existing +same-repository trust: other write-capable repository automation is trusted +not to deliberately impersonate this reviewer. It is not authenticated proof +that one exact publishing workflow issued a review POST. + +Head SHA, base ref, base SHA, open PR, newer owned attempts and target bindings +are revalidated before each dismissal. Dismissal uses one PUT attempt and an +exact-state reread; a lost response is reconciled, not blindly retried. Multiple +targets are not atomic, and GitHub offers no compare-and-dismiss transaction. +Partial success, denied resets and retained blocks are explicit in separate +receipts/job summaries, with manual-dismiss guidance. Human and unrelated reviews +never become reset targets; no stronger token or approval fallback is acquired. + +Automatic reset remains available only while the original accepted artifact and +verifiable binding exist. Pre-rollout reviews without complete original evidence, +expired/deleted artifacts (including evidence lost during a rerun), and uncertain +history require a maintainer's manual dismissal after reviewing the current +report. A clean completed review is not a claim of merge readiness or human approval. +Publication remains idempotent per run/attempt, never recreates a deleted/dismissed +historical verdict, and collapses only exact consumed/older reports with bodies +retained. Current native evidence, not stale working-comment text, authorizes it. ### Reusable Workflow Calls From a4f79d69bed5c3c86b098c61202630559a2f64ba Mon Sep 17 00:00:00 2001 From: Steve Gontzes Date: Mon, 12 Oct 2026 22:18:34 +0000 Subject: [PATCH 3/8] fix(review): validate native results from runner execution file Bind native completion to the current runner session instead of transporting the full structured body through env. Add trusted read-path settings, realistic MCP fixtures and file-transport regressions, and document required pre-merge runtime smoke.

After you post the final summary, CI reads the `**Blocking Issues: N**` +count from it, publishes the completed report, and submits a commit-bound +`--request-changes` when N > 0 or `--comment` when N == 0, linking to the report. +Your only obligation is an accurate count and a complete summary; a missing or +malformed count turns the whole run red, so always post the summary in the exact +template above. + +### Optional terminal proof for clearing this reviewer's prior blocks + +If `.github/review-reset.json` is available, read its frozen `audit` entries in +addition to Step 3.

Current native evidence, not stale working-comment text, authorizes it. +The agent posts its verdict in a working summary comment and never writes +review-state metadata. Before the agent runs, the action creates a fresh +provisional working comment for the run/attempt and binds it to the native +`update_claude_comment` MCP tool (`CLAUDE_COMMENT_ID`), so the agent passes +only the Markdown body and never chooses a repository, comment, or head +target. The body no longer travels through shell heredocs or `gh api` writes; +the tool keeps its upstream sanitization and secret redaction. GitHub's comment +size limit still applies, but the shell's command-length limit does not. The +existing broad `Bash(gh api:*)` permission remains; the prompt restricts its +intended use to metadata reads, not an enforced read-only boundary. This is a +transport fix, not credential isolation. The preflight binds a fresh slot, and +the publisher still validates the live head and report finality at completion. +After a successful run, CI publishes the report as a NEW +comment carrying a visible reviewed-commit link and CI-owned review-state +metadata (reviewed SHA, base, workflow, run, attempt, summary marker, verdict +mode), then submits a commit-bound request-changes review for blockers or a +neutral comment otherwise, linking directly to the report. This reviewer never +approves. Only after the formal review exists does CI mark the report +`publication: completed` — a completed report is the report PLUS its formal +result, so a report whose review never landed stays `pending`: preserved and +reconciled by identity for a same-attempt retry, but never the next run's +review-state baseline and never a comment the agent can edit. Only after +completion are the previous report (including any pending leftover) and the +consumed working comment collapsed — bodies retained, linked to the new +report — so a failed run leaves the previous report untouched. +Stale, provisional, foreign, or malformed working output cannot be published, and a +push during the run stops publication. Working output already consumed by a +published report is never republished without fresh model work, and an attempt +whose start predates an already-completed later attempt (compared by the actual +attempt start times recorded in each report, never run-ID order) is refused as +obsolete before publishing. Publication is idempotent per workflow run +and attempt: a repeated finalization reuses the already-published report and never +submits a second formal review, while an intentional new run or attempt gets a new +report. Completed reports are never handed back to the agent as update targets — +every run/attempt writes to its own freshly created provisional working comment, +while completed state is still selected independently for incremental review. +Active findings appear once in their severity section, labeled `New` or +`Prior — still present`. A compact resolved section records fixed/obsolete prior +findings with evidence; it does not repeat the active findings. + +### Clearing this reviewer's previous blocks + +Both profiles attempt self-dismissal by default, never approval. Before the +model runs, CI freezes exact reviews positively owned by this workflow/profile, +their original count-accounted blocking findings, and the existing prior-finding +audit inputs. A successful terminal response may supply a compact JSON audit +proof for those IDs with complete coverage, no blockers, and affirmative +current-code evidence. It supplements, rather than replaces, the normal review. +CI captures it from the runner execution file, sanitizes/redacts all persisted +evidence, and uploads one accepted reset artifact using repository retention +defaults. Editable summary prose is not reset authority. + +Only after normal publication completes with a neutral COMMENT does CI recheck +the PR head/base, frozen targets, original evidence, and competing/newer runs, +then dismiss those exact blocking reviews. A failed preparation, absent/malformed +proof, incomplete audit, failed upload, stale source, or ambiguous GitHub result +retains blocks without suppressing ordinary publication or changing its state +lifecycle. An incomplete review still keeps its provisional summary as before. +Reset warnings are visible in the workflow log; ambiguous writes are reconciled +by reading the exact review, never blindly retried. + +Human, foreign-profile, and unmarked legacy reviews are never targets. +Missing, edited-by-human, deleted-history, or count-unaccounted original finding +evidence requires manual handling; this is not a migration of every historical +block. Unknown-severity context findings are conservatively required to resolve. +An incomplete edit/competing-run inventory also retains the affected block +(including more than 100 original edits or GitHub's capped run listing). +No new permissions or caller opt-in are needed. The model retains its existing +tools and write-capable GitHub token: this host ordering is not adversarial +credential isolation and does not replace required human approval. ### Reusable Workflow Calls From 33f0271edb48e91e391b3819d9b3df3e20d3cd12 Mon Sep 17 00:00:00 2001 From: Steve Gontzes Date: Mon, 12 Oct 2026 23:18:38 +0000 Subject: [PATCH 5/8] Use the run workflow URL for required-workflow inventory Validate the returned workflow URL against the exact GitHub API root and repository, permitting standard and org-required workflow namespaces before paginating competing runs.
