Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00094 | $0.00252 |
| Opus 5 | $0.00047 | $0.00126 |
| Sonnet 5 | $0.00019 | $0.00050 |
| Haiku 4.5 | $0.00009 | $0.00025 |
Grade A, and why
canary scanned grade A 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 10d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
description: Generate a curl-based canary watcher script for a deployed URL. Validates URL is http/https, status code is 100-599, interval is 5-86400 seconds. The generated script supports one-shot (default) and --watch What it actually says
/canary
Lightweight uptime watcher.
When to use
- After deploying, to watch the new release
- Before a major event, as a heartbeat
- The user says "set up a watcher", "monitor X URL"
What it produces
scripts/canary.sh that uses curl. zero install. supports:
bash scripts/canary.sh # one-shot, exits 0/1
bash scripts/canary.sh --watch # continuous loop
Run it
dragoon canary https://example.com --apply
dragoon canary https://example.com --status 204 --interval 30 --apply
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.

canary is a skill published in the GitHub repository Dragoon0x/dragoon-skills (4 stars, last pushed 4mo ago), licensed MIT. It adds 94 tokens to every session and 252 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
