Add explicit clone isolation protocols and warnings to prevent agents
from manipulating the local repository in /app. This ensures:
- Agents use isolated /tmp/ clones for all source code operations
- No interference between parallel agents
- No disruption to developer's local work environment
- No conflicts from branch changes or file modifications
Updated agents:
- Core implementation agents (implementer, build, plan)
- Quality gate agents (lint-fixer, typecheck-fixer, test-fixer, etc.)
- Test writing agents (behave-tester, unit-test-runner, coverage-improver)
- Analysis agents (difficulty-evaluator, fix-pr)
- Special cases (build-opencode with .opencode/ exception)
Each agent now includes prominent warnings and proper isolation protocols
with detailed explanations of why clone isolation is critical for
system stability.
Updated multiple agents to understand and properly handle TDD (Test-Driven
Development) tags as documented in CONTRIBUTING.md. This prevents confusion
when agents encounter tests with @tdd_expected_fail that invert their behavior.
Key changes:
- Test writers (behave-tester, robot-tester) now understand when to use TDD tags
- Implementers know to remove @tdd_expected_fail tags when fixing bugs
- Test-fixer won't try to "fix" correctly passing TDD tests
- PR reviewers check for proper TDD tag removal in bug fix PRs
- Human liaison can explain TDD tags to confused developers
- Coverage improver avoids modifying TDD tests
- Reference reader includes TDD tag info in summaries
This ensures all agents work correctly with the TDD workflow where tests are
written before bug fixes and use special tags to prove bugs exist.
BREAKING CHANGE: Removed all tier-specific agents in favor of model-agnostic versions
Key changes:
- Create model-agnostic agents:
- behave-tester.md (replaces 4 tier-specific versions)
- robot-tester.md (replaces 4 tier-specific versions)
- coverage-improver.md (replaces coverage-checker with escalation)
- Convert existing agents to support escalation:
- lint-fixer.md (now model-agnostic)
- test-fixer.md (now model-agnostic)
- integration-test-runner.md (now model-agnostic)
- Update tier selectors to support all new agents
- Update quality-gate-escalator to handle all quality fixers
- Update subtask-loop to use quality-gate-escalator for all quality gates
- Empty redundant tier-specific agents for deletion:
- All implementer-{tier}.md files
- All behave-tester-{tier}.md files
- All robot-tester-{tier}.md files
- coverage-checker.md (replaced by coverage-improver.md)
Benefits:
- Eliminates ~90% code duplication
- All agents now support full 4-tier escalation (haiku→codex→sonnet→opus)
- Consistent escalation behavior across all agent types
- Single source of truth for each agent's logic
- Significant cost savings by defaulting to haiku for all quality gates
The system now uses tier selectors (tier-haiku, tier-codex, tier-sonnet,
tier-opus) that set the model and invoke model-agnostic worker agents,
eliminating the need for separate implementations per model tier.
