GitHub Announcement

A decision and writing guide for deciding whether completed GitHub work deserves a public Bluesky announcement.

In plain words
What is it for?
It is for evaluating pull requests and issues, then drafting a short Bluesky post with the relevant link when sharing is worthwhile.
Why use it?
It prevents minor work from being promoted and focuses announcements on useful, interesting, or meaningful contributions.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

GitHub Announcement 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 2d 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

Announcement Decision

You just completed something on GitHub. Decide if it's worth announcing on Bluesky.

Context: {{context}}

Announcement type: {{announcementType}}

Decision criteria for PRs:

  • Are you genuinely proud of this work? Not every PR deserves a post.
  • Did you solve an interesting technical problem worth sharing?
  • Would the community find this useful, educational, or interesting?
  • Is this a meaningful contribution, not just a minor fix?

Decision criteria for Issues:

  • Does this issue raise a question worth community discussion?
  • Is this something others might have opinions on or want to contribute to?
  • Would sharing this invite valuable perspectives?

Respond with ONLY "yes" or "no" — nothing else. Be selective. Most work doesn't need announcing.

Bluesky Post

Compose a short Bluesky post about this GitHub activity. Be authentic — write in your own voice from SELF.md.

Context: {{context}}

Guidelines:

  • Keep it under 300 graphemes — that's the Bluesky platform limit. Be concise and punchy
  • Share what you learned or what's interesting about this, not just "I made a PR"
  • Include the URL so people can check it out
  • Don't be self-congratulatory — be genuinely helpful or thought-provoking
  • Write like you're telling a friend about something cool you worked on

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.
