verify-validate-phase

verify-validate-phase is a skill for Claude Code, Codex from easyinplay/harnessed. It costs 123 tokens per session (1,374 once invoked), scanned A, original, Apache-2.0.

A verification workflow that checks whether project requirements are covered by tests after a development phase is complete. TDD means writing tests before implementation; this workflow also looks backward for requirements that those tests missed.

In plain words
What is it for?
It is for conditionally running a coverage audit when a phase requires one, producing a VALIDATION.md report and adding tests for uncovered requirements.
Why use it?
It helps find untested requirements that can remain hidden after the main implementation and test-writing work is finished.

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

verify-validate-phase 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 3d 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.

verify-validate-phase workflow (v3)

Overview

1-phase sub-workflow auditing requirement→test coverage gaps (v13.0 P43 upstream re-sync — D-04 Stage ④ Verify conditional sub + GSD validate-phase wire)。回溯审计 phase 完成后的 requirement→test 覆盖缺口,为未覆盖 requirement 生成测试 (gsd-nyquist-auditor agent), 补 TDD 前向写测试之外的后向查漏。

phase id upstream model capability gate
1 01-validate-phase gsd sonnet {{ capabilities.gsd-validate-phase.cmd }} judgments.stage-routing.verify-validate-phase-coverage.fires

Per-phase config loads from workflows/verify/validate-phase/workflow.yaml; engine 4-level gate resolver evaluates phase.requires_coverage_audit == true via expr-eval — true 则 invoke GSD /gsd-validate-phase (Nyquist 覆盖审计 → VALIDATION.md), false 则 skip。

Capability refs

How to invoke

!harnessed checkpoint intent verify-validate-phase

The banner above (when present) means this invocation is REGISTERED with the engine (an intent marker) — not yet compliant: the steps below (prompt → spawn → checkpoint complete) resolve it, and a per-turn <workflow-intent> reminder persists until they run.

The numbered sequence below is the state machine — execute it with Bash. Do NOT improvise an equivalent flow from the Overview above: freelancing bypasses the engine (no ledger, no evidence guard). harnessed gives you the spawn-ready prompt; YOU spawn the subagent with a CC-native Task / Agent tool (keeps the session responsive + lets clarification round-trips reach the user).

Do NOT pipe to harnessed run verify-validate-phase — that is the CI/headless path (in-process SDK spawn that blocks the session inside Claude Code).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
