validate-gap

validate-gap is a command for Claude Code from j5ik2o/event-store-adapter-js. It costs 9 tokens per session (837 once invoked), scanned A, a copy of kiro-validate-gap, Apache-2.0.

A command that compares written requirements with the code already in a project. It reads project guidance and analysis rules to identify what is missing and how the pieces might fit together.

In plain words
What is it for?
Use it to assess an unfinished feature, compare a specification with an existing codebase, and evaluate possible implementation approaches.
Why use it?
It helps reveal gaps and integration problems before implementation begins. It also shows where more technical research or design work is needed.

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-gap 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 4d 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.

Implementation Gap Validation

<background_information>

  • Mission: Analyze the gap between requirements and existing codebase to inform implementation strategy
  • Success Criteria:
    • Comprehensive understanding of existing codebase patterns and components
    • Clear identification of missing capabilities and integration challenges
    • Multiple viable implementation approaches evaluated
    • Technical research needs identified for design phase </background_information>

Execution Steps

  1. Load Context:

    • Read .kiro/specs/$1/spec.json for language and metadata
    • Read .kiro/specs/$1/requirements.md for requirements
    • Load ALL steering context: Read entire .kiro/steering/ directory including:
      • Default files: structure.md, tech.md, product.md
      • All custom steering files (regardless of mode settings)
      • This provides complete project memory and context
  2. Read Analysis Guidelines:

    • Read .kiro/settings/rules/gap-analysis.md for comprehensive analysis framework
  3. Execute Gap Analysis:

    • Follow gap-analysis.md framework for thorough investigation
    • Analyze existing codebase using Grep and Read tools
    • Use WebSearch/WebFetch for external dependency research if needed
    • Evaluate multiple implementation approaches (extend/new/hybrid)
    • Use language specified in spec.json for output
  4. Generate Analysis Document:

    • Create comprehensive gap analysis following the output guidelines in gap-analysis.md
    • Present multiple viable options with trade-offs
    • Flag areas requiring further research

Important Constraints

  • Information over Decisions: Provide analysis and options, not final implementation choices
  • Multiple Options: Present viable alternatives when applicable
  • Thorough Investigation: Use tools to deeply understand existing codebase
  • Explicit Gaps: Clearly flag areas needing research or investigation

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.
