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.

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 | $0.01327 |
| Opus 5 | $0.00000 | $0.00664 |
| Sonnet 5 | $0.00000 | $0.00265 |
| Haiku 4.5 | $0.00000 | $0.00133 |
Grade A, and why
create-backend-tests 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 3d 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 — 99 lines — stays where its author put it; the contents beside it link to each section on GitHub.

go tool cover -html=coverage.out
Critical Rules
1. Be Pragmatic
Write tests that add real value. If a test requires overly complex mocking or doesn't validate meaningful behavior, skip it. It's better to have no test than a brittle one that breaks with every minor change. If fighting with mocks, consider an integration test instead.
2. Test Behavior, Not Implementation
Focus on what the code does, not how. Don't test that specific internal methods were called or verify exact sequences of internal function calls.
3. No Historical Comments in Code
No // Added in TASK-0025 or // Testing new implementation. Historical context belongs in git commits. Tests should be self-explanatory.
4. Extend Existing Tests Before Creating New Ones
When code already has test coverage, prefer modifying or extending existing tests to cover new behavior rather than creating new test functions that largely duplicate what's already there. Add cases to existing table-driven tests when the scenario fits.
5. All Tests Must Pass
New tests are done ONLY when they ALL pass 100%. Don't leave failing tests. If a test is too complex to get right, don't write it.
6. No Documentation Files Unless Explicitly Requested
DO NOT create summary documents, README files, or any markdown documentation files (like test coverage summaries, test reports, etc.) unless the user explicitly asks for them. Focus exclusively on creating the actual test code.
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.

create-backend-tests is a command published in the GitHub repository codeready-toolchain/tarsy (10 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,327 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.
