verification

verification is a skill for Claude Code from YuDefine/nuxt-supabase-starter. It costs 16 tokens per session (1,010 once invoked), scanned A, original, MIT.

A verification-infrastructure workflow for creating or maintaining checks that exercise product features. It can map features to checks and run a full launch, diagnosis, interaction, evidence, and cleanup cycle.

In plain words
What is it for?
Use it to create missing verification infrastructure or reconcile and live-test existing feature checks.
Why use it?
It helps keep verification checks aligned with the product as features change, without treating test evidence alone as final acceptance.

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

verification 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 8d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/check-feature-map.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Verification infrastructure

verification 是 consumer verification infrastructure 的統一入口:create 建立 verify-<app> skill 與 feature map 並實證一次閉環,maintain 對帳既有 feature map 並 live re-prove;只維護 verification infrastructure,不宣告產品驗收。

改編自 Lauren Tan 的 pstack create-verification-skill/maintain-verification-skill,授權見 references/UPSTREAM.md。

SOP

Phase 1 -- 判定 mode 與定位 target

  1. READ 找 <skills-root>/verify-*/SKILL.md(<skills-root> 依 runtime:Claude .claude/skills/、Codex .agents/skills/;找不到該目錄就回報標準未送達,不猜一個)。
  2. THINK 零個 → create(Phase 2);一個且要更新或重跑 → maintain(Phase 5);多個 → 請使用者指定,不靠名稱相似度猜。只收集 UI 截圖交 /review screenshot;implementation 與規格對帳讀 specs/truth/** 與該 work 的 carrier 自行對帳,動到規格回交 truth owner skill。

Phase 2 -- create:訪談 repo

  1. THINK 先讀取 rules/repo訪談六欄判準.md,從 repo 與實跑結果回答 Surface/Launch/Doctor/Drive/Observe/Isolate;不能 build 或 launch 就停下回報 baseline blocker。

Phase 3 -- create:產生 verify skill 與 feature map

  1. WRITE 先讀取 rules/verify-skill產出判準.md、templates/verify-app.md 與 templates/verify-app.example.md,在 canonical 位置寫 <skills-root>/verify-<app>/SKILL.md。
  2. WRITE 先讀取 rules/feature-map結構判準.md、templates/verification-map-README.md、templates/verification-map-README.example.md、templates/verification-feature.md 與 templates/verification-feature.example.md,寫 features/README.md 與最重要的 3–5 個 feature。

Phase 4 -- create:驗結構並實跑一次閉環

  1. DELEGATE 執行 node <skills-root>/verification/scripts/check-feature-map.mjs <skills-root>/verify-<app>,exit 0 才往下;結構紅時只修 verification skill,不改產品 code 來迎合文件。
  2. DELEGATE 實跑一次完整閉環 Launch → Doctor → Drive one mapped feature → Capture evidence → Cleanup;失敗 iteration 也 cleanup,最後確認 evidence 在 cleanup 後仍存在。
  3. WRITE 先讀取 rules/create完成證據判準.md,逐格勾完成證據,交代 target、已實跑 feature、evidence path、unreachable prerequisites,並指出後續用 /verification maintain。

Phase 5 -- maintain:驗索引與 source wave

  1. DELEGATE 執行同一支 node <skills-root>/verification/scripts/check-feature-map.mjs <skills-root>/verify-<app>,修 missing/extra/duplicate/dead index entry;同時先讀取 rules/維護編輯範圍判準.md 確認可改範圍。
  2. DELEGATE 先讀取 rules/source-wave與對帳判準.md,依 clade routing threshold 以 read-heavy prescan 收集每個 feature 的 source evidence,再依規則對帳。

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.

verification is a skill published in the GitHub repository YuDefine/nuxt-supabase-starter (44 stars, last pushed 2d ago), licensed MIT. It adds 16 tokens to every session and 1,010 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-14.
