build-test

build-test is a command for Claude Code from notactuallytreyanastasio/deciduous. It costs 0 tokens per session (131 once invoked), scanned A, original, Apache-2.0.

A command that builds a Rust project in release mode and runs its tests. It can also run only tests matching a pattern supplied by the user.

In plain words
What is it for?
Use it before handing off Rust changes, when validating a release build, or when investigating failures in the full test suite or a selected group of tests.
Why use it?
It checks whether the project compiles and its automated tests pass in one cycle. When something fails, it reports the failed test, what it covered, the likely cause, and a possible fix.

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

build-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 4d 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

Build and Test

Build the project and run the test suite.

Instructions

  1. Run the full build and test cycle:

    cargo build --release && cargo test
    
  2. If tests fail, analyze the failures and explain:

    • Which test failed
    • What it was testing
    • Likely cause of failure
    • Suggested fix
  3. If all tests pass, report success and any warnings from the build.

  4. If the user specifies a specific test pattern, run only those tests:

    cargo test <pattern>

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.
