validate

validate is a skill for Claude Code from tim-mccrimmon/structured-context-spec. It costs 24 tokens per session (1,896 once invoked), scanned A, original, Apache-2.0.

A user-run review check for a project's structured YAML context and generated files. It checks required fields, linked documents, consistency, content gaps, and compilation output.

In plain words
What is it for?
Use it to review structured project context, confirm that referenced documents and imports resolve, and identify items that need human attention.
Why use it?
It helps find broken references, missing information, placeholders, and out-of-sync generated files before the project is versioned.

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

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 28d 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.

Invocation Rules

  • User-initiated only: Do NOT invoke this skill unless the user explicitly runs /scs-team:validate. Never auto-invoke based on project state or conversation context.

SCS Team Validate - Structure Check and Review Surface

You are validating the user's structured context and surfacing issues that need human review before versioning.

Validation Levels

Level 1: Syntax

  • Valid YAML
  • Required fields present (id, version, title, description)
  • Correct structure

Level 2: References

  • All SCDs referenced in bundles exist
  • All bundle imports can be resolved
  • No circular dependencies

Level 3: Consistency

  • Version consistency (all DRAFT or all versioned)
  • Tier consistency (SCDs in correct tier)
  • ID format correctness

Level 4: Content Quality (Human Review Items)

  • Placeholder content detection
  • Incomplete sections
  • Generic/template text not customized
  • TBD items that need resolution

Level 5: Compilation Check

  • Compiled output exists in .claude/rules/ for each concept with SCDs
  • Compiled files have <!-- scs-team:managed --> ownership header
  • CLAUDE.md has <!-- scs-team:start --> / <!-- scs-team:end --> markers
  • Compiled output is not stale (all concepts with SCDs have corresponding rules files)

Concept Coverage Assessment

Assess coverage across all 11 concepts:

# Concept Expected SCDs
1 Architecture system-context, tech-stack, integration-map, component-model
2 Security authn-authz, data-protection, data-handling, threat-model
3 Performance & Reliability response-time, availability, fault-tolerance, scalability
4 Usability & Accessibility ux-principles, accessibility-compliance, error-handling-ux
5 Compliance & Governance hipaa-compliance, soc2-controls, audit-requirements, policy-enforcement
6 Data & Provenance data-model, provenance-tracking, retention-policy
7 Testing & Validation test-coverage, validation-plan, qa-procedures
8 Deployment & Operations infrastructure-definition, observability, incident-response
9 Safety & Risk risk-assessment, safety-checklist

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.
