hf.test-adequacy

hf.test-adequacy is a command for Claude Code from T-rav/hydraflow. It costs 0 tokens per session (467 once invoked), scanned A, original, Apache-2.0.

A read-only check that evaluates whether changed production code has enough tests, including tests for edge cases and errors.

In plain words
What is it for?
Use it after implementation or during review to inspect diffs and check whether each changed function or class has suitable tests.
Why use it?
It shows where changed code lacks test coverage before the work is committed or merged.

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

hf.test-adequacy 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 5d 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.

Test Adequacy Check

Assess whether changed production code has adequate test coverage. This is a read-only assessment — it does not modify files.

When to Use

  • After implementing changes, before committing
  • To verify test coverage is adequate for the changes
  • When reviewing a branch for test completeness

Instructions

  1. Get the diff of changes on the current branch:

    git diff origin/main...HEAD
    

    If that's empty, fall back to git diff (unstaged) or git diff --cached (staged).

  2. Identify all changed or added production files (exclude test files).

  3. For each changed production function/method/class, verify:

    • Has a corresponding test — at least one test exercises the new/changed code path
    • Edge cases covered — empty inputs, None values, boundary conditions, error paths
    • Regression safety — if existing behavior changed, tests verify the new behavior
    • No test-only gaps — new test utilities or fixtures are themselves tested if non-trivial
  4. Produce structured output:

If coverage is adequate:

TEST_ADEQUACY_RESULT: OK
SUMMARY: All changed code has adequate test coverage

If gaps exist:

TEST_ADEQUACY_RESULT: RETRY
SUMMARY: <comma-separated list of gap categories>
GAPS:
- <production_file:function — what test is missing>

Important

  • Do NOT modify any files. This is a read-only assessment.
  • Focus on whether production code is tested, not test code style.
  • Ignore test file changes when assessing adequacy.
  • Be pragmatic: simple getters/setters don't need dedicated tests. Focus on logic, branches, and error paths.

Note: implementer-loop gate also runs a deterministic coverage-delta check

When test-adequacy runs inside the implementer loop (not this interactive slash command), AgentRunner._run_skill additionally runs make coverage 0 after the LLM verdict and overrides a PASS to RETRY if any changed production line has zero coverage hits. This slash command remains read-only and LLM-only; the subprocess coverage check is an implementer-loop-only behaviour.

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.

hf.test-adequacy is a command published in the GitHub repository T-rav/hydraflow (5 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 467 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.
