phase-workflow

phase-workflow is a skill for Claude Code from gosha70/code-copilot-team. It costs 24 tokens per session (2,347 once invoked), scanned A, original, MIT.

Rules for moving work through planned build phases and verifying that required documents, tests, and deliverables are complete before a phase is marked finished.

In plain words
What is it for?
Use it to check specifications, approve plans, verify phase outputs, and control the transition from planning to building.
Why use it?
It prevents incomplete work from being reported as done and catches missing plans or unresolved questions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

phase-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Phase Workflow — Post-Phase Verification

Standardized steps to complete after each build phase, regardless of stack.

Spec Artifact Verification

Post-Plan Verification

After Plan phase completes, verify:

  • specs/<feature-id>/plan.md exists with spec_mode in YAML frontmatter
  • If spec_mode is full or lightweight: spec.md exists in the same directory
  • No unresolved [NEEDS CLARIFICATION] markers remain in spec.md

Pre-Build Check

Before Build phase starts, verify based on spec_mode:

  • full: spec.md present, no unresolved [NEEDS CLARIFICATION], plan.md approved
  • lightweight: spec.md present, no unresolved [NEEDS CLARIFICATION], plan.md approved
  • none: plan.md present and approved — no further spec artifacts required

Phase Completion Integrity

Rules preventing false completion claims. Derived from a real incident where Claude marked a phase complete with major deliverables missing, then suggested experimental work.

No partial completion

Never mark a phase as complete when deliverables are missing. If a phase has two deliverable clusters (e.g., auth middleware + chat UI) and only one is built, the phase is partially complete. Report exactly what is done and what remains.

No summary laundering

When presenting phase status, compare against the latest approved plan/spec (plan.md, spec.md, and tasks.md when present) — not your memory of what was built. If the approved plan says "Auth/RBAC + UI Split into Chat UI and Admin Console" and you only built auth, do not rewrite the summary as "Role-based auth middleware, CORS preflight." Report the gap.

No stretch before core

Never suggest experimental, nice-to-have, or post-plan work when core deliverables from the current or earlier phases are incomplete. If the plan has sequencing prerequisites (e.g., "only pursue after Phase N gates are met"), enforce them.

Regression detection on removal

When existing functionality is removed or replaced during a phase (e.g., replacing a Dash app with FastAPI), verify the replacement is functional before closing the phase. A regression from "working app" to "no app" is a hard blocker — not a separate bug to fix later.
