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 | $0.00000 | $0.04313 |
| Opus 5.5 | $0.00000 | $0.01725 |
| Sonnet 5.5 | $0.00000 | $0.00863 |
| Haiku 4.5 | $0.00000 | $0.00431 |
Grade A, and why
sdd-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 2mo 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.

The opening of the file, as written. The whole thing — 783 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SDD Validate Command
Validate constitutional compliance and requirements coverage.
Instructions for Claude
You are executing the /sdd-validate [feature-name] command to validate constitutional compliance and requirements coverage for a feature.
Command Format
/sdd-validate authentication
/sdd-validate payment-processing
/sdd-validate user-dashboard
Your Task
Perform comprehensive validation of the feature implementation against:
- Constitutional Articles (9 articles)
- Requirements coverage (100% traceability)
- Code quality standards
- Security standards
- Test coverage
Process
1. Read All Documentation
IMPORTANT: Always read ENGLISH versions (.md) as they are the reference/source.
# Requirements and Design (English versions)
storage/specs/{{feature-name}}-requirements.md
storage/specs/{{feature-name}}-design.md
storage/specs/{{feature-name}}-tasks.md
# Steering Context (English versions)
steering/structure.md
steering/tech.md
steering/product.md
steering/rules/constitution.md
# Source Code
lib/{{feature}}/src/**/*.ts
lib/{{feature}}/tests/**/*.test.ts
app/api/{{resource}}/**/*.ts
Note: Japanese versions (.ja.md) are translations only. Use English versions for validation.
2. Constitutional Validation
Validate each of the 9 Constitutional Articles:
Article I: Library-First Principle
Requirement: All new features SHALL begin as independent libraries.
Validation Steps:
- Check
lib/{{feature}}/directory exists - Verify library structure:
-
lib/{{feature}}/src/exists -
lib/{{feature}}/tests/exists -
lib/{{feature}}/package.jsonexists - Public API exported via
src/index.ts
-
- Verify NO dependencies on application code:
- Grep for imports from
app/,pages/, etc. - Library should only import from own
src/or external packages
- Grep for imports from
Example Output:
### Article I: Library-First Principle
**Status**: ✅ PASS
**Evidence**:
- Library location: `lib/auth/`
- Public API: `lib/auth/src/index.ts`
- Independent tests: `lib/auth/tests/`
- No application dependencies found
**Files Checked**:
- lib/auth/src/service.ts
- lib/auth/src/repository.ts
- lib/auth/src/index.ts
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.

sdd-validate is a command published in the GitHub repository nahisaho/CodeGraphMCPServer (14 stars, last pushed 11mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,313 tokens. 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 2026-08-30.
