racecraft-plugins-public: Skill for Claude Code

.claude/skills/speckit-validate/SKILL.md

speckit-validate is a skill for Claude Code from racecraft-lab/racecraft-plugins-public. It costs 20 tokens per session (716 once invoked), scanned A, a copy of speckit-speckit-utils-validate, MIT.

A checker that compares a feature’s written specification with its task list and completed files. It verifies task status, expected file paths, and links between requirements and work.

In plain words
What is it for?
Validating completed specification-driven work, finding missing files, and reporting requirements or tasks that lack traceable implementation evidence.
Why use it?
A checked task does not always mean the expected file exists or that the implementation matches the specification. This exposes those gaps.

Skill for Claude Code

Written for Claude Code: $ARGUMENTS substitution.

This is racecraft-lab/racecraft-plugins-public's own configuration. It tells Claude Code how to work on racecraft-plugins-public itself, so it is not a mod to install elsewhere.

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

speckit-validate 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.

Origin

This is a copy

88% identical to speckit-speckit-utils-validate — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

User Input

$ARGUMENTS

Outline

Deterministically verify that the implementation matches the specification by checking task completion, file existence, and requirement traceability.

Step 1: Select feature

If $ARGUMENTS specifies a feature name or number, use that. Otherwise, find the most recently modified feature in specs/.

If no features exist, error: "No features found in specs/. Run /speckit.specify first."

Step 2: Parse tasks

Read tasks.md from the feature directory. Parse each checkbox line:

  • Extract task text (after - [x] or - [ ])
  • Mark as completed or remaining
  • Extract keywords: file paths (auth/login.py), snake_case names (user_auth), CamelCase names (UserAuth), dotted names (config.yaml)

If no tasks.md exists, error: "No tasks.md found. Run /speckit.tasks first."

Step 3: Verify completed task artifacts

For each completed task that references file paths:

  1. Search the project directory for the referenced file
  2. If found: PASS
  3. If not found: WARN ("task says 'Create auth/login.py' but file not found")

Skip verification for:

  • Incomplete tasks (not yet implemented)
  • Tasks with no file path references (e.g., "Set up CI pipeline")

Step 4: Parse spec requirements

Read spec.md from the feature directory. Extract items from the "Functional Requirements" section (bulleted list items under that heading).

If no requirements section found, skip to Step 6.

Step 5: Trace requirements to tasks

For each requirement, search task descriptions for matching keywords:

  • Tokenize the requirement into significant words (skip stop words)
  • Check each task's text for overlap (2+ matching keywords = traced)

Report:

  • Requirement with matching tasks: PASS ("traced to Task N")
  • Requirement with no matching tasks: WARN ("no task found for this requirement")

Step 6: Report

Output a validation report:

Validation Report: 001-auth
============================

Task Completion: 3/5 (60%)
  [x] Task 1: Create auth/login.py      -> auth/login.py FOUND
  [x] Task 2: Add password hashing      -> (no file reference)
  [x] Task 3: Write auth tests          -> tests/test_auth.py FOUND
  [ ] Task 4: Add rate limiting         -> (not yet implemented)
  [ ] Task 5: Update API docs           -> (not yet implemented)

Requirement Traceability: 3/3
  "Users can log in with email"          -> Task 1 (PASS)
  "Passwords are stored securely"        -> Task 2 (PASS)
  "Users can reset password via email"   -> (no matching task - WARN)

Summary: 2 PASS, 1 WARN, 0 FAIL

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.
