A bug-fixing command for a Kotlin project that follows TDD, or test-driven development: write a test that fails, make the smallest fix, then confirm the tests pass. It traces the bug through the app's layers and follows the project's architecture and testing rules.

Use it to reproduce bugs, identify the affected layer and files, write a focused test, implement a minimal fix, run relevant tests, and check compilation.

It gives bug fixes a repeatable process and helps prevent changes in the wrong part of the app. The failing test records the problem before the fix is made.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 393 The whole file, excluding the scripts and references it only reads on demand.

Security scan A 0 findings. Scan, not verified.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5	$0.00000	$0.00393
Opus 5	$0.00000	$0.00197
Sonnet 5	$0.00000	$0.00079
Haiku 4.5	$0.00000	$0.00039

Measured 5d ago against content hash 02dc32e47552, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

fix 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.

Bug

$ARGUMENTS

Process (TDD — Red-Green-Refactor)

REPRODUCE: Find the relevant code. Trace the data flow: Screen → ViewModel → UseCase → Repository → DataSource Show: what's wrong, why, which layer, file paths + line numbers. Wait for "go".
RED — Write a failing test first:
- Name: `should {expected} when {condition}`
- AAA pattern, Mokkery for mocks, Turbine for Flows
- Run: ./gradlew :{module}:allTests --tests "*TestClass" — confirm FAILS
GREEN — Minimal fix:
- Fix only the bug, nothing else
- Respect layer boundaries: DTOs in data, domain stays pure, Ui in feature
- If fix crosses layers — fix in the correct layer per architecture
VERIFY:
- New test PASSES
- All tests in affected module(s) PASS: ./gradlew :{module}:allTests
- Compile check: ./gradlew :{module}:compileCommonMainKotlinMetadata
UPDATE rules if the bug revealed an undocumented gotcha:
- Add to .claude/rules/conventions.md or CLAUDE.md Build Gotchas

Rules

Never ./gradlew test without --tests filter
Never break existing tests
Minimal diff — don't touch what isn't broken
If fix needs a new UseCase → follow architecture rules
If fix needs model changes → update mappers in ALL layers
If unsure → ask, don't guess

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.

fix is a command published in the GitHub repository satanyakiv/NutriSport (11 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 393 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 2026-08-30.
