agent-coverage-check

agent-coverage-check is a skill for Claude Code from majiayu000/claude-skill-registry. It costs 23 tokens per session (462 once invoked), scanned A, a copy of agent-coverage-check, MIT.

A checking tool for finding missing coverage in a multi-level team of coding agents and across different development phases. It reports whether the expected agents are present for each level, phase, and project section.

In plain words
What is it for?
It is for checking agent levels, development phases, and project sections with dedicated coverage scripts.
Why use it?
It helps reveal gaps in an agent system before an important task is missed. This is useful when the agent hierarchy grows and becomes hard to check by hand.

Getting it into your agent

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

agent-coverage-check 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 9d 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.

What it actually says

Agent Coverage Check

Verify complete agent system coverage across all dimensions.

When to Use

  • After adding new agents to system
  • Validating agent system completeness
  • Finding gaps in coverage
  • Ensuring all development phases covered

Quick Reference

# Check all coverage dimensions
./scripts/check_agent_coverage.sh

# Check specific dimension
./scripts/check_level_coverage.sh
./scripts/check_phase_coverage.sh
./scripts/check_section_coverage.sh

Coverage Dimensions

Hierarchy Levels:

  • L0: Chief Architect (1)
  • L1: Section Orchestrators (6)
  • L2: Design Agents (per section)
  • L3: Specialists (per module)
  • L4: Engineers
  • L5: Junior Engineers

Development Phases:

  • Plan
  • Test
  • Implementation
  • Package
  • Cleanup

Sections:

  • Foundation
  • Shared Library
  • Tooling
  • First Paper
  • CI/CD
  • Agentic Workflows

Coverage Report Format

Hierarchy Coverage:
  L0: ✅ 1 agent
  L1: ✅ 6 agents
  L2: ✅ 12 agents
  L3: ✅ 24 agents
  L4: ✅ 3 agents
  L5: ✅ 1 agent

Phases:
  Plan: ✅ Covered

  Shared Library: ✅ Orchestrator + agents

Gap Patterns

Missing level: Any level with 0 agents

Missing phase: Phase not assigned to any agent

Missing section: Section without orchestrator

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.
