Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.
Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.
PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.
Currently being processed by an implementer worker.
Currently being processed by the merge driver.
Currently being processed by a reviewer worker.
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.
In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.
Tracking issues used by the AI Automation system for agents to communicate and report.
Rebase conflict needs LLM conflict-resolver.
Failing CI needs implementer attention.
Documenting a driver incident or rollback.
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
A ticket in a blocked state and unable to complete until some other task is completed first.

Review Summary
Reviewed PR #3390 with focus on specification-compliance, requirements-coverage, and behavior-correctness.
This is a documentation-only PR adding a single bullet point to
docs/specification.md. The actual change is minimal and correct — but there is one blocking metadata issue that must be resolved before merge.✅ What Was Reviewed
Actual Change (single commit
46c9fe8d):✅ Passing Checks
Specification Compliance ✅ — The added bullet accurately documents the MCP 1.4.0 error extraction protocol as implemented in PR #2600. The three key behaviors are correctly captured:
isError: truetriggers error extractioncontent[0].text(not a top-levelerrorkey)"unknown error"whencontentis absent or malformedRequirements Coverage ✅ — The addition satisfies all requirements from issue #3330. It is slightly more complete than the proposal (adds the fallback behavior), which is an improvement.
Behavior Correctness ✅ — The documented behavior matches the implementation in PR #2600. The spec now correctly describes the wire format per MCP 1.4.0.
Commit Message Format ✅ —
docs(spec): document MCP 1.4.0 error extraction from content[0].text in MCPToolAdapterfollows Conventional Changelog format correctly.Closing Keyword ✅ —
Closes #3330is present in the PR body.ISSUES CLOSED: #3330is also in the commit message.Labels ✅ —

1. Missing Milestone
Location: PR metadata
Issue: The Forgejo API shows
"milestone": nullfor this PR. The PR comment from the implementation agent claims the milestone was set tov3.7.0, but the current API state shows it is not set.Required: Set the milestone to
v3.7.0(or the appropriate active milestone) before merge.Reference: CONTRIBUTING.md — Pull Request Process section requires PRs to have a milestone assigned.
To fix: Update the PR milestone via the Forgejo UI or API to
v3.7.0.Minor Observations (Non-blocking)
Decision: REQUEST CHANGES 🔄
One blocking issue: Missing milestone (currently
nullin API, should bev3.7.0).Once the milestone is set, this PR is ready to merge. The content change itself is correct, minimal, and well-justified.
