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 5.1 | $0.00177 | $0.02061 |
| Opus 5 | $0.00088 | $0.01030 |
| Sonnet 5 | $0.00035 | $0.00412 |
| Haiku 4.5 | $0.00018 | $0.00206 |
Grade A, and why
canary-generate-test 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 9d 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 — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Canary: Generate Test
Generate a framework-appropriate test from a natural-language requirement. Routes through Canary's classify → recommend → generate pipeline, writes the test under
tests/generated/, and optionally executes it.
When to Use
- When the user asks to scaffold a new test from a natural-language description ("write a test for X", "I need an API test that does Y")
- When triaging a bug report into a regression test
- When extending an existing test suite with a new case but the framework choice is ambiguous
- NOT for editing existing tests — use the project's normal edit flow
- NOT for choosing between frameworks abstractly — use the framework-registry docs, not this skill
- NOT for running existing tests — use the framework's CLI directly
Relative to the other "write a test" paths
This skill is the batch generation path (the /canary-write-test slash
command) — use it for scripted/CI-driven generation runs consumed
programmatically from tests/generated/. For an interactive, session-generated
test with a human reviewing framework and code before it lands, use
agents/canary-test-author.md (wired to /canary-write-test). For a
single-file, automatic write-run-revise loop via MCP tools, use
agents/canary-test-generator.md.
Process
Phase 1: CLARIFY — Resolve the Requirement
- Confirm test type if ambiguous. If the prompt doesn't clearly indicate
unit | api | e2e | performance, ask one targeted question before invoking the pipeline. The classifier will guess, but a wrong guess costs a regeneration. - Confirm target framework if the user has a preference. The recommender will pick by category from the registry; if the user explicitly wants Playwright but the registry would pick Cypress for the category, surface that mismatch now.
- Capture concrete inputs. Endpoint URL, payload shape, expected status, selectors, performance thresholds — whatever the test actually needs. Vague prompts produce vague tests.
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.

canary-generate-test is a skill published in the GitHub repository bop-clocktower/canary (4 stars, last pushed today), licensed MIT. It adds 177 tokens to every session and 2,061 once invoked, about $0.0009 per session on Opus 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 2026-08-31.
