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.

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 5.1 | $0.00016 | $0.00323 |
| Opus 5.5 | $0.00006 | $0.00129 |
| Sonnet 5.5 | $0.00003 | $0.00065 |
| Haiku 4.5 | $0.00002 | $0.00032 |
Grade A, and why
tdd-cycle 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.
What it actually says
TDD cycle
Read the complete workflow for task-file conventions. Repository paths are relative to the repository root. The canonical quality gate and coordinator responsibilities in .agnostic-ai/AGNOSTIC_AI.md apply.
Use .tasks/YYYY-MM-DD-slug.md for features, refactors, or multi-test work; skip it for small fixes or a single test. Choose the next smallest test from the acceptance scenario or task inventory and study matching existing tests.
- RED: Write Arrange-Act-Assert, run
./bashunit <test-path>, and verify failure proves the requested behavior is missing, rather than a syntax or setup error. Record the red bar and logbook entry when using a task file. - GREEN: Implement only what this test requires. Run the focused test and require a pass. Check off the inventory entry and record the result.
- REFACTOR: Improve naming, structure, or duplication without changing behavior. Keep affected focused tests green; preserve other workers' changes. Record meaningful refactoring notes.
- Repeat until the acceptance scenario is complete. The main session runs the full quality gate once after the whole change set, before committing. Delegates run only assigned targeted checks.
Never skip the demonstrated RED or add speculative behavior during GREEN. Keep the task inventory and logbook current when a task file is used.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

tdd-cycle is a skill published in the GitHub repository TypedDevs/bashunit (435 stars, last pushed today), licensed MIT. It adds 16 tokens to every session and 323 once invoked, about $0.0001 per session on Opus 5.5. 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.
