Title#

Add pre-PR quality gate and /agent skip-quality-gate directive

Problem#

Agent-created PRs lacked automated quality checks before opening, risking lint failures, test regressions, or merge conflicts landing in review. There was also no way to bypass checks for known-good emergency changes.

Task / Link#

Closes #228

Changes#

• Add skip-quality-gate to ALLOWED_DIRECTIVES and VALID_DIRECTIVES; directive sets a one-time override flag on the task and posts a confirmation comment without re-dispatching
• Add qualityGateOverride boolean column (default false) to TaskEntity
• Add setQualityGateOverride method to TaskStateService
• Pass QUALITY_GATE_OVERRIDE=1 env var to the deliver phase invocation when override is set; reset flag atomically before phase starts (one-time use)
• Create scripts/tools/pre-pr-gate.sh — runs lint, tests, and merge conflict check; emits a structured markdown table; accepts --skip for override mode; exits non-zero on failure

Notes#

• .claude/skills/deliver-implementation/SKILL.md and .claude/skills/implement-code/pr-description-standard.md are planned changes (integrate pre-pr-gate.sh into deliver flow, add Quality Checks section to PR description standard) but were blocked by the permissions system during this run. Those skill files require a follow-up edit with appropriate permissions.
• The qualityGateOverride column uses a SQLite default (false), so existing in-flight tasks are unaffected without a migration.

Quality Checks#

Testing#

• npm run lint — 0 errors (4 pre-existing warnings in unrelated file)
• npm run test — all 638 tests pass including 3 new quality gate override tests in phase-router.service.spec.ts and 2 new tests in directive.service.spec.ts
