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

No concerns identified. This is a targeted, low-risk improvement that addresses a well-documented pattern of implementer failures. Proceeding to merge.

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.
