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 | $0.00000 | $0.00805 |
| Opus 5.5 | $0.00000 | $0.00322 |
| Sonnet 5.5 | $0.00000 | $0.00161 |
| Haiku 4.5 | $0.00000 | $0.00081 |
Grade A, and why
test-authoring 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 6d 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

Test Authoring skill
name: test-authoring version: 0.1.1 summary: Reusable guidance for adding or updating tests in this repository without tying the workflow to a single agent product.
Purpose
Help an agent create, extend, or reorganize tests while following this repository's current conventions for unit tests, automated device smoke tests, and manual device helpers.
Activation conditions
Activate when an agent needs to:
- add a new test for existing code
- update tests after changing tool behavior or response contracts
- move tests into the correct unit, automated device, or manual device location
- improve coverage for handlers, server contracts, or shared utilities
Surface area (actions)
- choose-test-type
- place-test-file
- mirror-existing-pattern
- add-or-update-fixtures
- validate-test-command
- document-test-scope
Core guidance
- Prefer the smallest reliable test type: unit test first, automated device smoke test only when real platform integration matters, manual helper only when automation is not practical.
- Follow the repository's current automated test style: self-running
tsxscripts with explicit assertions and non-zero exit on failure. - Put automated unit tests under
test/unit/...; the unit runner automatically executes every*.test.tsfile there. - Put automated device smoke tests under
test/device/automated/...; put human-invoked helpers undertest/device/manual/.... - Prefer the extracted services’ typed dependencies and injectable clocks over replacing static methods or process-global timers. Reuse existing test seams before adding hooks.
- When testing user-facing tools, protect response shape, required fields, and documented defaults.
- Keep tests deterministic: isolate process-global mocks, prefer fake binaries or injected helpers over shared mutable module state.
- Run
npm run verifyfor code/test changes and applicable native checks under the shared process. - Follow the structure and architecture rules. Keep guardrail failure cases under
test/unit/quality/and preserve the complete public tool-definition compatibility fixture.
What ships with it
3 files 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.

test-authoring is a skill published in the GitHub repository clivejefferies/mobile-debug-tools (14 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 805 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.
