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 | $0.00558 |
| Opus 5.5 | $0.00000 | $0.00223 |
| Sonnet 5.5 | $0.00000 | $0.00112 |
| Haiku 4.5 | $0.00000 | $0.00056 |
Grade A, and why
validate-impl scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Validate Implementation
Perform full traceability validation from requirements through design to implementation.
Usage
/kiro:validate-impl <feature-name>
Instructions
-
Read all spec documents:
.kiro/specs/$FEATURE_NAME/requirements.md.kiro/specs/$FEATURE_NAME/design.md.kiro/specs/$FEATURE_NAME/tasks.md
If any are missing, report which files are absent.
-
Build the traceability chain:
- Requirements -> Design components (from design traceability section)
- Design components -> Tasks (from task traceability section)
- Tasks -> Files (from task file lists)
-
For each requirement, trace the full chain:
- Which design component addresses it?
- Which task(s) implement that component?
- Which files were created/modified?
- Does the implementation actually satisfy the requirement?
-
Validate implementation correctness:
- Read each implemented file referenced in tasks
- Check that the code matches the design's API contracts
- Verify error handling matches specified error cases
- Verify data validation matches model specifications
- Check that tests exist and cover the requirement
-
Check acceptance criteria:
- For each task, verify all acceptance criteria are met
- Run tests if possible to confirm passing state
-
Generate full traceability report:

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.

validate-impl is a command published in the GitHub repository kaze-jp/kusa (2 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 558 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 2026-08-31.
Other commands, from other repositories
checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
constitution
Create or update the project constitution from interactive or provided principle inputs.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
