slackcli: Skill for Claude Code

.claude/skills/release/SKILL.md

release is a skill for Claude Code from shaharia-lab/slackcli. It costs 87 tokens per session (1,894 once invoked), scanned A, original, MIT.

A release procedure for SlackCLI, a command-line tool, covering the work from reviewing commits through publishing a new version. It uses Semantic Versioning, a version-numbering system, and separates the reversible pull request from the final tag that publishes binaries and updates the Homebrew package source.

In plain words
What is it for?
It is for surveying changes, choosing a version bump, opening the release issue and pull request, updating the changelog, checking signatures, and publishing the confirmed release.
Why use it?
It reduces release errors involving version mismatches, unsigned commits, missing linked issues, and premature publishing. It also requires human confirmation before the irreversible tagging step.

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

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 1mo 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cutting a SlackCLI release

A release is two separate things, in this order:

  1. A PR onto main that bumps package.json and promotes the CHANGELOG. Reversible.
  2. An annotated tag pushed to that merged commit. This is the irreversible, outward-facing step — release.yml builds and publishes public binaries, and force-updates the Homebrew tap at shaharia-lab/homebrew-tap.

Never do step 2 without explicit human confirmation. See Gate before tagging.

Hard constraints

These are the ways a release goes wrong. Check them, don't rediscover them.

  • release.yml fails when the tag disagrees with package.json (#82). The bump must be merged into main before the tag is pushed. Fixing it after the fact means bumping main and then deleting and re-pushing the tag.
  • main requires signed commits, with no bypass actors — an unsigned commit makes the PR unmergeable for anyone, including admins. Verify the release commit carries a signature.
  • The repository constitution in CLAUDE.md applies to the release PR too: it needs a linked GitHub issue carrying ready-for-pr before the PR is opened. pr-linked-issue.yml enforces the link as a required check.
  • main requires one approving review, and an agent cannot approve its own PR. So gh pr merge reports BLOCKED / REVIEW_REQUIRED even when every check is green. Unblocking it is the maintainer's decision, taken one of two ways — a review, or an explicit instruction to merge with --admin. Never pick --admin on your own initiative; surface the block and let the maintainer choose. dismiss_stale_reviews_on_push is on, so any push after an approval discards it — get the branch final before asking for review.
  • Pre-commit hooks block direct commits to main. Always work on a branch.
  • A merged PR does not guarantee a CHANGELOG entry. Reconcile commits against [Unreleased] yourself — the mrkdwn fix in #96 landed with no entry and had to be backfilled at v0.9.0.
  • bun may not be on PATH in a non-interactive shell. If bun is not found, use export PATH="$HOME/.bun/bin:$PATH".

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.
