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 | $0.00057 | $0.00858 |
| Opus 5 | $0.00028 | $0.00429 |
| Sonnet 5 | $0.00011 | $0.00172 |
| Haiku 4.5 | $0.00006 | $0.00086 |
Grade A, and why
bird 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 4d 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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
bird — X/Twitter CLI
This skill targets my @dannote/bird-premium package, which installs a bird binary. It is a fork of/derived from Peter Steinberger's original steipete/bird CLI, but uses the documented paid X API v2 instead of undocumented web GraphQL/cookie endpoints.
- Package:
@dannote/bird-premium - Original project credited:
steipete/bird - Transport: official X API v2 with OAuth 1.0a and Bearer Token auth
Install
# one-shot (no install)
bunx @dannote/bird-premium whoami
# or install globally
npm install -g @dannote/bird-premium
# or: pnpm add -g @dannote/bird-premium

Authentication
Env vars:
- Bearer Token (app-only):
X_BEARER_TOKEN - OAuth 1.0a (user context):
X_API_KEY,X_API_SECRET,X_ACCESS_TOKEN,X_ACCESS_TOKEN_SECRET
Bearer Token enables: search, read, user, user-tweets, followers, following OAuth 1.0a adds: tweet, reply, like, retweet, bookmark, follow, home, whoami, mentions

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.

bird is a skill published in the GitHub repository dannote/dot-pi (51 stars, last pushed today), licensed MIT. It adds 57 tokens to every session and 858 once invoked, about $0.0003 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 2026-08-30.
