08-verify-build

name	08-verify-build
description	Runs quality checks at milestone boundaries during the build. Auto-corrects lint and format issues without blocking. Only blocks on test failures, type errors, or security issues that require user decisions. Invoked by 07-build at milestone and phase boundaries, not as a separate pipeline step.

08 — Verify Build

Run quality checks in parallel, auto-correct where possible, and surface non-trivial failures to the user.

Preamble: pipeline-preamble.md — shared conventions for stages 00–19. Sessions: sessions-reference.md — requires active_session unless waived; reports under docs/sessions/{id}/reports/. Cross-cutting: considerations.md, connectivity-gates.md. State agent: workflow-state-manager — mandatory read/update.

Connectivity (stage 08)

Blocking: tests/unit/test_cors_policy.py and tests/integration must pass. Report connectivity artifact presence (test_staging_connectivity.py, verify_connectivity.sh) in `{artifacts_dir}/reports/verification-report.md``. See connectivity-gates §Stage 08.

When to Use

• During 07-build: Automatically invoked at milestone and phase boundaries
• Standalone: Can verify the codebase at any point
• Pre-PR: Run before creating minor or major PRs

Behavior: Non-Blocking Auto-Correction

Unlike a traditional gate that blocks until everything is clean, this skill uses a tiered approach:

Issue Type	Action	Blocking?
Lint errors (auto-fixable)	Auto-fix with --fix flag	No
Format issues	Auto-format	No
Lint errors (manual)	Present to user	Yes
Type errors	Present to user	Yes
Test failures	Present to user	Yes
Security issues	Present to user	Always blocking
Data integrity	Present to user	Advisory (not blocking)

Prerequisites

1. workflow-state.yaml + execution plan artifact — §Tech Stack Summary for tool commands
2. Source files and tests must exist

Session management

{artifacts_dir} = active_session.artifacts_dir from workflow-state-manager.

Per sessions-reference.md §10 and workflow-state-agent-protocol.md.

1. Agent read_context must return active_session (or blocking deviation).
2. Current stage must appear in active_session.routing_plan unless user amends plan.
3. Write stage reports to active_session.artifacts_dir/reports/ when this stage produces a report.
4. On completion: update routing-plan entry status; mirror project.stages.{key} via agent update.
5. 00-context exempt from active_session requirement (session opener). Report: reports/verification-report.md.

State management

Agent protocol: workflow-state-agent-protocol.md. Stage key: stages.08-verify-build.

Invoke workflow-state-manager read_context before any other action; update after each substep. Do not edit workflow-state.yaml directly.

Detail: {artifacts_dir}/reports/verification-report.md`` — overwrite each run; set report` on the stage block.

Delta / feature-addition mode

• Run at 07-build milestone boundaries for delta tasks only.
• Scope verification to changed modules and tests tied to new Fn.

Workflow

Phase 1 — Load Configuration

Read workflow-state.yaml + execution plan artifact §Tech Stack Summary for tool commands.

Phase 2 — Run Checks (Parallel)

Launch agents in one message:

Agent 1 — Linter: Run lint, parse findings, classify as auto-fixable or manual.

Agent 2 — Formatter: Run format check (dry-run mode).

Agent 3 — Typechecker: Run typecheck, parse errors.

Agent 4 — Test Suite: Run full test suite, parse results. Must include H0c tests/unit/test_cors_policy.py (blocking for hybrid UI deploys).

Agent 4b — Connectivity policy (deployed service hybrid): Confirm configure_cors on browser-facing FastAPI apps and tests/smoke/test_staging_connectivity.py exists per connectivity-gates.

Agent 5 — Security: Always runs:

• pip-audit for dependency CVEs
• Pattern scan for committed secrets
• Common vulnerability patterns (eval, pickle.loads, etc.)

Agent 6 — Performance (optional): Only when specs define perf thresholds.

Agent 7 — Data Integrity (optional): Verify staged data assets if they exist.

Agent 9 — Modal run smoke (optional, milestone M10+ or pre-deploy): Per ADR-004 T1. Run only when user approves GPU budget via AskQuestion. Uses curl or httpx ephemeral invocations (same minimum set as 13 Phase 1.5). Skip on Windows dev machines without platform CLI — record SKIPPED in verification report.

Agent 8 — Template Conformance (if template selected): Read workflow-state.yaml §template and template-registry.md. Verify:

• File layout matches template structure (src/app.py, src/service.py or src/utils.py)
• Modal patterns match template type (api vs worker vs monolith)
• No Modal imports in the core logic module
• CI/CD workflow file matches template pattern
• App name is cognichem-{service_name}
• For job: all GPU classes have i_am_running(), @modal.enter() calls warmup()
• For utility: no @modal.enter(), no GPU, no volumes
• Return: conformance report with deviations listed

Phase 3 — Auto-Correct

For auto-fixable issues (lint auto-fix, format):

1. Apply fixes automatically
2. Re-run only the affected check to confirm
3. Commit: chore: auto-fix lint/format issues
4. Report what was auto-fixed

Phase 4 — Surface Non-Trivial Failures

For issues requiring user decisions, present via AskQuestion:

Lint (manual): "Approve auto-fix / Deny (false positive) / Modify (manual fix)" Type errors: "Approve fix / Deny (suppress) / Modify (provide correct type)" Test failures: "Fix implementation / Fix test / Both need changes" Security: "Upgrade packages and remove secrets / Accept risk / Review individually"

Phase 5 — Compile Report

Write `{artifacts_dir}/reports/verification-report.md``:

# Verification Report

> Generated: [date]
> Scope: [milestone/phase/standalone]
> Branch: [branch]

## Summary

| Check | Status | Findings | Auto-Fixed | Tool |
|-------|--------|----------|------------|------|
| Lint | PASS | [N] | [N] auto-fixed | [tool] |
| Format | PASS | [N] | [N] auto-fixed | [tool] |
| Typecheck | PASS/FAIL | [N] | — | [tool] |
| Tests | PASS/FAIL | [N] failed | — | [tool] |
| Security | PASS/FAIL | [N] | — | pip-audit |
| Performance | PASS/SKIPPED | — | — | [tool] |
| Data | PASS/SKIPPED | — | — | verify_data.py |

Overall: PASS / FAIL

Phase 6 — Re-verify (if fixes applied)

After user-approved fixes:

1. Re-run affected checks
2. If new failures appear, loop back to Phase 4
3. Maximum 3 fix-verify loops

Output Rules

1. Auto-correct first: Fix what can be fixed automatically before presenting to user
2. Parallel checks: All checks run simultaneously
3. Security always blocking: Never auto-dismiss security findings
4. Max 3 loops: Prevent infinite fix-verify cycles
5. Report persists: Written to disk for PR and downstream reference
