fix(guardrails): address code-reviewer findings — 3 CRITICAL + 4 HIGH by terisuke · Pull Request #146 · Cor-Incorporated/opencode

terisuke · 2026-04-08T16:03:21Z

Summary

Follow-up to PR #145 addressing code-reviewer findings.

CRITICAL-1: Guard all workflow phase transitions with current phase check
CRITICAL-2: parseFindings() matches structured patterns only (not prose)
CRITICAL-3: Remove --no-verify from team.ts auto-commit
HIGH-1: Use MUTATING_TOOLS.has() in tool.execute.before (multiedit gated)
HIGH-2: Increment workflow_review_attempts, cap at 3
HIGH-3: Phase transitions: PR create only from "implementing", test only from "testing", merge only from "shipping"
HIGH-4: Ship agent denies --admin and --auto flags

Test plan

Guardrails scenario tests pass (34/34)
Typecheck clean (13/13)

🤖 Generated with Claude Code

CRITICAL-1: Guard workflow transitions with current phase check — prevents state pollution from manual operations in non-pipeline sessions CRITICAL-2: parseFindings() now matches structured patterns ([CRITICAL], **HIGH**) at line start, excludes injected context and negations CRITICAL-3: Remove --no-verify from team.ts auto-commit — pre-commit hooks must not be bypassed for security/quality gates HIGH-1: Use MUTATING_TOOLS.has() in tool.execute.before — multiedit now gated for secret files, config files, and version baselines HIGH-2: Increment workflow_review_attempts in autoReview(), cap at 3 — blocks infinite review loops with workflow_phase="blocked" HIGH-3: All phase transitions guarded by currentPhase check — PR create only from "implementing", test pass only from "testing", merge only from "shipping" HIGH-4: Ship agent denies gh pr merge --admin and --auto flags Also: system.transform issue guidance gated behind active pipeline, ci_green resets to false on non-passing checks Code-reviewer: 3 CRITICAL + 4 HIGH + 5 MEDIUM + 3 LOW (all CRITICAL/HIGH addressed) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Pull request overview

Follow-up hardening of the guardrails autonomous workflow pipeline based on prior code-review findings (phase transition gating, auto-review parsing/attempt limits, safer ship-agent permissions, and removing auto-commit hook bypass).

Changes:

Removes --no-verify from team.ts auto-commit during worktree merge-back.
Updates guardrail auto-review parsing and introduces workflow_review_attempts tracking with a max-attempts block.
Tightens workflow phase transitions and tool gating (including multiedit) and restricts ship-agent merge flags.

File	Description
`packages/guardrails/profile/plugins/team.ts`	Removes `--no-verify` from the auto-commit used when merging delegated worker changes.
`packages/guardrails/profile/plugins/guardrail.ts`	Updates auto-review finding parsing, review-attempt counting, mutating-tool gating, and workflow phase transition logic.
`packages/guardrails/profile/agents/ship.md`	Adds rules intended to deny `gh pr merge` with `--admin` / `--auto`.

+      const trimmed = line.trim()
+      // Skip negation lines
+      if (/\b(no|zero|0|none|without|aren't|isn't|not)\b/i.test(trimmed)) continue
+      // Skip injected guardrail context lines (e.g., "CRITICAL=0 HIGH=0")
+      if (/CRITICAL=\d|HIGH=\d|checklist|Guardrail mode/i.test(trimmed)) continue
+      // Match structured patterns: leading marker or bracketed/bold severity


parseFindings() skips any line containing the word "not" (and other negation tokens). This will incorrectly ignore legitimate findings like "- CRITICAL: do not ..." or "HIGH: not safe ...", causing undercounting of findings and weakening review gates. Consider tightening negation detection to only match explicit summary lines (e.g., lines that start with "No/Zero/None" + severity), or run the structured severity match first and only apply negation filtering when the line is a negated summary.

    }
    const findings = parseFindings(result.text)
+    const attempts = num(data.workflow_review_attempts) + 1
+    if (attempts >= 3) {


The review-attempt cap looks off by one: attempts is incremented before the check, and the code blocks when attempts >= 3. That allows only 2 completed review cycles even though the workflow prompt says "max 3 cycles". If the intent is to allow up to 3 attempts, block only when attempts > 3 (or >= 4), and still persist the incremented count consistently.

Suggested change

if (attempts >= 3) {

if (attempts > 3) {

      if (item.tool === "bash") {
        const cmd = str(item.args?.command)
        const output = str(out.output)
+        const currentPhase = str(bashData.workflow_phase)


bashData is referenced here but is not defined in the tool.execute.after hook scope (only data is). This will fail typecheck / runtime. Use the data already loaded in this hook, or fetch a fresh snapshot with await stash(state) inside this block before reading workflow_phase.

Suggested change

const currentPhase = str(bashData.workflow_phase)

const currentPhase = str(data.workflow_phase)

+      // Follow-up issue guidance — only during active pipeline
+      if (phase && phase !== "idle" && phase !== "done") {
+        out.system.push(
+          "When you discover problems outside the current scope, create follow-up issues: `gh issue create --title '<desc>' --body '<details>' --label 'tech-debt'`. Do NOT fix out-of-scope problems inline."
+        )
+      }


The comment says follow-up issue guidance is shown only during an "active pipeline", but the condition includes the "blocked" phase (it only excludes idle/done). If blocked should not be treated as active, align this condition with the pipelineActive logic (exclude "blocked" too).

+    "gh pr merge * --admin*": deny
+    "gh pr merge * --auto*": deny
    "gh pr merge*": allow


The deny rules for gh pr merge flags are ineffective as written: permission evaluation uses the last matching rule, and "gh pr merge*": allow comes after the deny entries, overriding them for --admin/--auto merges. Also, the patterns "gh pr merge * --admin*" / "... * --auto*" can be bypassed by putting the flag first (e.g., gh pr merge --admin 123). Move the deny rules after the allow rule (or narrow the allow rule), and use patterns that match the flag in any position (e.g., without requiring an extra arg before the flag).

Suggested change

"gh pr merge * --admin*": deny

"gh pr merge * --auto*": deny

"gh pr merge*": allow

"gh pr merge*": allow

"gh pr merge*--admin*": deny

"gh pr merge*--auto*": deny
