test

A command for planning or running focused tests for a coding task, bug, or code change. TDD means writing a test to describe expected behaviour before implementing the change.

In plain words
What is it for?
Use it to reproduce bugs, add behaviour-focused tests, run narrow validation, and report results, changes, risks, and remaining coverage.
Why use it?
It provides a defined validation process, reducing the chance of claiming a fix without evidence or adding tests that only check internal implementation details.

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.

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.

What it actually says

Test objective:

$ARGUMENTS

Use the matching local skills:

  • test-driven-development for behavior changes, bugs, or new tests.
  • debugging-and-error-recovery when there is a failure, trace, or unexpected behavior.

Flow:

  1. Identify expected behavior, scope, and success criteria.
  2. For bugs, reproduce first with a test or observable evidence.
  3. Add or adjust the minimum test that proves the behavior.
  4. Run the narrowest useful validation.
  5. If implementation is needed to make the test pass and scope is clear, implement the minimum code required.
  6. Run final reasonable validation and summarize the evidence.

Rules:

  • Do not replace /feature when spec, research, or scope decisions are missing.
  • Do not write tests that only verify fragile internals.
  • Do not claim success for a reproducible bug unless you saw the new test fail, unless you explain why that was not viable.
  • Do not expand refactors beyond the tested behavior.

Deliver:

  1. Test or validation added.
  2. Before/after result when applicable.
  3. Implementation changes, if any.
  4. Commands run.
  5. Risks or pending coverage.
Changes

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 command published in the GitHub repository jcarlosrodicio/opencode-agent-orchestration-kit (105 stars, last pushed 4d ago), licensed Apache-2.0. It adds 15 tokens to every session and 269 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.
