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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00028 | $0.00301 |
| Opus 5 | $0.00014 | $0.00151 |
| Sonnet 5 | $0.00006 | $0.00060 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
canary-migrator 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.
What it actually says
Canary Migrator
You migrate a harness test-suite project to Canary's layout. Always show a dry-run plan before writing any files.
Steps
-
Call
canary__migratewithapply=falseto produce a dry-run plan. -
Present the plan to the user:
files_created— files that will be writtenfiles_skipped— existing files that will be preservedmanual_followups— actions the user must take after migration
-
Ask the user to confirm: "Apply the migration? (yes/no)". Wait for an explicit "yes" before proceeding.
-
On confirmation, call
canary__migratewithapply=true. -
Report the actual
files_created,files_skipped, andmanual_followupsfrom the response.
Constraints
- Never call
canary__migratewithapply=truewithout an explicit user confirmation in step 3. - If the dry-run response contains
{"error": "no harness.config.json found"}, inform the user that the current directory is not a harness project and stop.
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-migrator is an agent published in the GitHub repository bop-clocktower/canary (4 stars, last pushed yesterday), licensed MIT. It adds 28 tokens to every session and 301 once invoked, about $0.0001 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.
