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 | $0.00331 | $0.01258 |
| Opus 5.5 | $0.00132 | $0.00503 |
| Sonnet 5.5 | $0.00066 | $0.00252 |
| Haiku 4.5 | $0.00033 | $0.00126 |
Grade C, and why
sandbox-test-setup scanned grade C with 1 finding 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 18d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
Confirm, then `rm -rf public/assets` (gitignored, no need to ask): The source is not reproduced here
Licensed AGPL-3.0
The repository is licensed AGPL-3.0, which this catalogue does not treat as permission to reproduce the file. Read it at the source.
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.

sandbox-test-setup is a skill published in the GitHub repository bikeindex/bike_index (308 stars, last pushed today), licensed AGPL-3.0. It adds 331 tokens to every session and 1,258 once invoked, about $0.0013 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
Other skills, from other repositories
typescript-testing
Applies repository-aware TypeScript test design, behavior evidence, isolation, and mock-boundary criteria. Use when writing or reviewing unit tests.
test-sweep
Run all test suites (unit, integration, API, E2E) and aggregate results into a summary report. Use after completing execution slices or before the Review Gate.
testing
Use when writing tests, running tests, adding test coverage, or debugging test failures. Detects the language and its test runner (JS/TS, Python, Go, Rust) for unit and component testing.
frontend-testing
Scaffold and advise on frontend testing for production readiness, mapped to the Front-End-Checklist Testing category (13 rules). Defines a testing pyramid (unit, integration, E2E, visual, a11y, cross-browser, real-device, perf-budget, mutation, error-monitoring, coverage, mocking, contract) and emits copy-pasteable…
unit-testing-architecture-steer
Prioritize establishing robust unit test infrastructure in scenarios/{{TARGET}}/ across all service directories (ui/, api/, sidecars). This skill steers toward a testing foundation that makes it easy for agents and developers to add, maintain, and trust tests.
test-generator
A generator that reads Python functions and creates pytest test-file skeletons with parameterized example inputs. Pytest is a Python testing tool, and TDD means writing tests as part of the implementation process.
