A verification workflow for checking completed feature, bug, interface, API, mobile, security, or deployment work against acceptance criteria. It records evidence from the relevant checks.

Use it to select appropriate unit, integration, end-to-end, mobile, security, migration, or deployment checks and document their results.

It helps teams prove that delivered work meets its stated requirements before handoff.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00023	$0.01102
Opus 5.5	$0.00009	$0.00441
Sonnet 5.5	$0.00005	$0.00220
Haiku 4.5	$0.00002	$0.00110

Security

Grade A, and why

verify-work 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 11d 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 Work Skill

[!IMPORTANT] Verify feature, bug, UI, API, mobile, security, or deployment work against acceptance criteria.

Instructions

When the user asks to perform this workflow, execute the following steps:

Verify Work Workflow

Goal: Prove the delivered change works against explicit acceptance criteria before handoff.

Load the approved brief/acceptance criteria and changed files; use inherited operator_profile and risk tier. Preserve sensitive minimum medium risk (high when required); require PRD/SRS trace only for governed work.
Select applicable unit/component, integration/API, E2E/visual, mobile, security, migration, and deployment-smoke lanes.
Run smallest reliable checks first. Use Playwright/Appium only for changed user behavior; run driver scripts/preflight.sh and use first available rung (web: CLI then MCP; mobile: local then cloud). Missing required driver without exported proof is BLOCKED (driver: <name>). Use ticket/TC integrations only when configured; otherwise request exports or mark that lane BLOCKED.
- Capture applicable logs, screenshots, traces, or terminal summaries as <AC|step>-<before|after>.* under .playwright-cli/<session>/ or .appium-mcp/<session>/.
- For bug fixes, prove before-failure and after-success; preserve every applicable driver and verification lane.
PASS only when all approved criteria are proven and required approval/independent review gates are met; FAIL when a defect or missed requirement remains; BLOCKED when environment, credentials, or approval prevents proof. Feature verified status confirms technical delivery against contract; separate delivery proof from observed business success (delivery != causal ROI).
If observed behavior exceeds the approved low-risk brief, do not silently change scope or redefine criteria: route the decision to the owner, then verify against the resolved contract. Governed behavior drift requires PRD/SRS updates before PASS.
Record low-risk checks, outcomes, and evidence in chat/task report; do not require new BRD/PRD/SRS, task-list, REQ/AC-ID, trace, or walkthrough artifacts. Governed work updates BRD-to-PRD-to-SRS/FRS trace and docs/srs/srs-walkthrough-[slug].md. When initiative uses product evidence (docs/product/<slug>/evidence.json), carry measurement owner, registered MET baseline OR exact scoped exception DEC, query, instrumentation, cohort, window, guardrails, and review trigger; never fabricate agent-created baselines, approvals, or ROI. Proposal in ledger is not host execution or deployment permission.

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.
