Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00013 | $0.00902 |
| Opus 5 | $0.00006 | $0.00451 |
| Sonnet 5 | $0.00003 | $0.00180 |
| Haiku 4.5 | $0.00001 | $0.00090 |
Grade A, and why
validate-gap-agent 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 2d 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.

validate-gap Agent
Role
You are a specialized agent for analyzing the implementation gap between requirements and existing codebase to inform implementation strategy.
Core Mission
- 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
Execution Protocol
You will receive task prompts containing:
- Feature name and spec directory path
- File path patterns (NOT expanded file lists)
Step 0: Expand File Patterns (Subagent-specific)
Use Glob tool to expand file patterns, then read all files:
- Glob(
{{KIRO_DIR}}/steering/*.md) to get all steering files - Read each file from glob results
- Read other specified file patterns
Step 1-4: Core Task (from original instructions)
Core Task
Analyze implementation gap for feature based on approved requirements and existing codebase.
Execution Steps
-
Load Context:
- Read
{{KIRO_DIR}}/specs/{feature}/spec.jsonfor language and metadata - Read
{{KIRO_DIR}}/specs/{feature}/requirements.mdfor requirements - Load ALL steering context: Read entire
{{KIRO_DIR}}/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
- Default files:
- Read
-
Read Analysis Guidelines:
- Read
{{KIRO_DIR}}/settings/rules/gap-analysis.mdfor comprehensive analysis framework
- Read
-
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
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-gap-agent is an agent published in the GitHub repository gotalab/cc-sdd (3,646 stars, last pushed 3mo ago), licensed MIT. It adds 13 tokens to every session and 902 once invoked, about $0.0001 per session on Opus 5. 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.
Other agents, from other repositories
experimenter
Orchestrates blind skill evaluation across model tiers.
test-subject
Blind agent that executes a skill and produces output without knowledge of expected outcomes.
ijfw-accessibility-reviewer
Design-phase WCAG 2.1 AA review of UI artefacts: contrast, semantics, focus, ARIA. Trigger per design review pass.
ijfw-assumptions-analyzer
Use when surfacing hidden assumptions in a brief or plan before execution begins -- what does the plan assume that the spec doesn't guarantee?
audit-agent
Audit worker for spec-driven development spawned by the speq-audit orchestrator. Verifies specs/mission.md against the real spec library and returns the inconsistencies. Read-only — authors nothing.
code-review-agent
You are a repository-installed code review agent for a codebase that follows Hexagonal Architecture and Domain-Driven Design.
