announce-release

announce-release is a command for Claude Code from marcusgoll/Spec-Flow. It costs 16 tokens per session (944 once invoked), scanned A, original, MIT.

A command that prepares a release announcement for X, formerly Twitter, with a reply containing the GitHub release link.

In plain words
What is it for?
Use it to extract release highlights, preview and edit the post, confirm or skip publication, post to X, and add the GitHub link in a thread reply.
Why use it?
It turns a changelog into a proposed announcement and requires confirmation before anything is posted, while providing a fallback if posting fails.

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

announce-release 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.

What it actually says

This command delegates to the x-announcement skill which:

  • Generates engaging post from CHANGELOG
  • Gets user confirmation before posting
  • Posts main announcement via API
  • Replies with GitHub release link in thread
  • Handles errors gracefully without blocking
  1. Invoke x-announcement skill via Skill tool:

    • Pass version number
    • Let skill handle entire workflow (generate → confirm → post → reply)
  2. Skill workflow will:

    • Extract highlights from CHANGELOG for version
    • Show preview with character count
    • Get user confirmation (post/edit/skip)
    • Post to X API if approved
    • Poll for tweet ID
    • Reply with GitHub link
    • Display both tweet URLs
  3. Handle skill completion:

    • Success: Display tweet URLs
    • Failure: Show manual posting fallback
    • Skip: Continue without announcement

<version_detection> If version argument provided:

VERSION="$ARGUMENTS"  # e.g., "2.7.0"

If no argument (detect latest):

# Try git tag first
VERSION=$(git describe --tags --abbrev=0 2>/dev/null | sed 's/^v//')

# Fallback to CHANGELOG
if [ -z "$VERSION" ]; then
  VERSION=$(grep -m 1 "^## \[" CHANGELOG.md | grep -oP '\[\K[^\]]+')
fi

# Validate version found
if [ -z "$VERSION" ]; then
  echo "❌ Could not detect version. Specify manually:"
  echo "   /announce-release 2.7.0"
  exit 1
fi

</version_detection>

<success_criteria>

  • Version number detected or validated
  • x-announcement skill invoked successfully
  • User confirmation obtained before posting
  • X announcement posted (or gracefully skipped)
  • GitHub link reply posted in thread (or manual fallback provided)
  • Tweet URLs displayed to user
  • Release workflow unblocked on any X announcement failure </success_criteria>

<anti_patterns> Avoid:

  • ❌ Blocking on X announcement failures
  • ❌ Posting without user confirmation
  • ❌ Exceeding 280 character limit
  • ❌ Failing silently without fallback
  • ❌ Exposing API credentials or URLs publicly

Correct:

  • ✅ Always get user confirmation before posting
  • ✅ Validate character count before submission
  • ✅ Provide manual posting fallback on errors
  • ✅ Continue gracefully on any failure
  • ✅ Keep API details internal-only </anti_patterns>

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.
