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 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.

Agent Improvement Implementation
Implements approved proposal #2879.
Changes Made
Files:
.opencode/agents/ca-implementer-sonnet.md,.opencode/agents/ca-implementer-codex.md,.opencode/agents/ca-implementer-opus.mdAdded a new step 3 ("Verify domain model fields exist") to the "## Your Task" section of all three implementer agent definitions, between the existing "Read existing code" step and the "Implement" step:
Added domain model verification step: Before writing code that references any field, method, or attribute on a domain model class, the implementer MUST verify it exists by reading the actual class definition.
Added explicit guidance: Never assume a field exists based solely on the issue description. Issue descriptions often describe desired behavior — the field may not yet exist.
Added creation guidance: If a required field or method does not exist, the implementer must CREATE it as part of the implementation (including database schema changes if needed).
Renumbered subsequent steps: Steps 4-5 became 5-6 to accommodate the new step 3.
Evidence
During the v3.7.0 build session, multiple implementer agents created code referencing non-existent domain model fields:
Session.automation_profile(doesn't exist)SessionService.list_messages()(doesn't exist)This caused 5 Pyright type errors on master (issue #2109) and runtime crashes on session CLI commands.
Expected Impact
Closes #2879

Summary
This PR adds a critical domain model verification step to all three implementer agent definitions (
ca-implementer-sonnet,ca-implementer-codex,ca-implementer-opus). The change is well-motivated by documented evidence of real failures during the v3.7.0 build session.What was reviewed

Deep Dive: Test Coverage Focus Areas
Given my assigned focus on test-coverage-quality, test-scenario-completeness, and test-maintainability:
This PR modifies only agent prompt definition files (
.opencode/agents/*.md). These are configuration/documentation files that define agent behavior through natural language instructions — they are not executable source code. Therefore:This is the correct approach — the effectiveness of these prompt changes will be validated empirically through future implementer agent runs, not through automated tests.
