test-coverage is a command for coding agents from Fmarzochi/EGC. It costs 5 tokens per session (429 once invoked), scanned A, original, Apache-2.0.

Analyze and improve test coverage.

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

test-coverage 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 today.

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

Test Coverage Command

Analyze test coverage and identify gaps: $ARGUMENTS

Your Task

  1. Run coverage report: npm test -- --coverage
  2. Analyze results - Identify low coverage areas
  3. Prioritize gaps - Critical code first
  4. Generate missing tests - For uncovered code

Coverage Targets

Code Type Target
Standard code 80%
Financial logic 100%
Auth/security 100%
Utilities 90%
UI components 70%

Low Coverage Files

[Files below target, prioritized by criticality]

Uncovered Lines

[Specific lines that need tests]

Test Generation

For each uncovered area:

[Function/Component Name]

Location: src/path/file.ts:123

Coverage Gap: [description]

Suggested Tests:

describe('functionName', () => {
  it('should [expected behavior]', () => {
    // Test code
  })

  it('should handle [edge case]', () => {
    // Edge case test
  })
})

Coverage Improvement Plan

  1. Critical (add immediately)

    • file1.ts - Auth logic
    • file2.ts - Payment handling
  2. High (add this sprint)

    • file3.ts - Core business logic
  3. Medium (add when touching file)

    • file4.ts - Utilities

IMPORTANT: Coverage is a metric, not a goal. Focus on meaningful tests, not just hitting numbers.

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.
