test

A tool for generating and running software tests, including coverage plans and TDD workflows. TDD, or test-driven development, means writing a failing test before implementing the behavior that should make it pass.

In plain words
What is it for?
Use it to add tests, record a genuine failing test in TDD mode, run focused and full test suites, and produce repeatable coverage evidence.
Why use it?
It provides evidence that new behavior works and helps prevent unreliable tests that pass without checking meaningful results.

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 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.

How it starts

The opening of the file, as written. The whole thing — 244 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Test Skill

Generate real tests, run them, and leave reproducible coverage or TDD evidence. Do not stop at a plan unless the requested mode is strategy.

Critical Constraints

  • Why: behavior is the contract. Derive tests from acceptance scenarios and public behavior, not implementation details or coverage percentages alone.
  • Why: prove new behavior. In TDD mode record a real failing test before the minimal implementation; a test that starts green is not RED evidence.
  • Why: avoid false confidence. Assert exact values, error types/messages, and branch outcomes; ban zero-assertion, tautological, and padding tests.
  • Why: keep suites trustworthy. Tests must be deterministic, isolated, and independent of timing, ordering, production services, or mutable shared state.
  • Why: protect user intent. Report a product bug discovered by a test; do not silently change product behavior or delete existing tests without approval.
  • Why: close with proof. Run the narrow test after each edit, then the relevant suite and coverage command before handing work downstream.

Modes

Mode Use when Required result
generate writing tests for existing code passing focused and suite tests
coverage finding and filling important gaps before/after coverage plus tests
tdd implementing new behavior test-first logged RED → green → refactor cycles
strategy designing test architecture only inventory, risks, and recommendations

Default to generate. Flags: --mode, --scope, --min-coverage, and --dry-run narrow the workflow but never weaken its evidence requirements.

Oracle-strength hierarchy

Every test asserts through an oracle, and oracles are not equal. Rank them:

exact value > property/invariant > differential (two implementations agree) > smoke (it ran)

Choose the strongest oracle the behavior admits and name the oracle-strength tier when a test uses anything below exact. A smoke assertion where an exact one was available is the oracle downgrade failure mode: the test runs the code but proves almost nothing about it. Stop condition: no acceptance scenario may be covered only by smoke-tier tests when a stronger oracle is practical; if only smoke is practical (e.g. nondeterministic external output), record why in .agents/scratch/tests/summary.md so the gap is a visible decision, not an accident.

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.

test is a skill published in the GitHub repository boshu2/agentops (431 stars, last pushed 4d ago), licensed Apache-2.0. It adds 25 tokens to every session and 2,447 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.
