chamber: Skill for Claude Code

.github/skills/release/SKILL.md

release is a skill for Claude Code, Codex from ianphil/chamber. It costs 139 tokens per session (6,959 once invoked), scanned A, original, MIT.

A release procedure for publishing Chamber builds through either an invite-only insiders channel or a public stable channel. Chamber is the software project whose builds are being distributed.

In plain words
What is it for?
Publishing builds to insiders, releasing stable versions publicly, sending builds to testers, and promoting a version to the public channel.
Why use it?
It provides the steps and destinations needed to make a build available to testers or the public. It also distinguishes releasing a build from shipping a code change such as a pull request.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is ianphil/chamber's own configuration. It tells Claude Code and Codex how to work on chamber itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything chamber configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node scripts/bump-insiders-version.js --dry-run.

Reuse

Borrowing it

Nothing to install: this file belongs to ianphil/chamber. Take a copy, put it at the same path in your own repository, and replace the rules that are about this project with yours.

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 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 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.

How it starts

The opening of the file, as written. The whole thing — 690 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Release Skill

Dispatch a Chamber release. Two channels, picked deliberately, dispatched manually. Authoritative mechanics live in ai-docs/release-channels.md; this skill is the operational runbook on top of them.

This skill is not the same as ship. Ship lands PRs. Release publishes builds. Neither calls the other.

When to invoke

Trigger on any of these (or close variants):

  • "release", "release insiders", "release stable", "cut a release"
  • "ship a build" (when distinct from "ship a PR" — ask if unclear)
  • "publish", "publish stable", "publish to GitHub Releases"
  • "promote", "promote insiders", "promote to stable"
  • "make a build available to testers", "send to testers", "push to insiders"
  • "go public with this", "make this the public version"

If the user's intent is ambiguous between PR shipping and build shipping, ask once. If the channel is ambiguous, ask once.

Channels

Channel Audience Workflow Distribution Platforms
Insiders Invite-only .github/workflows/release-insiders.yml Azure Blob chamberinsiders Windows + macOS arm64; Linux x64 preview
Stable Public .github/workflows/release.yml GitHub Releases Windows + macOS arm64 (+x64 opt-in; macOS can be disabled by repo variable)

Both are workflow_dispatch only — neither fires on push.

The core shape to keep in mind:

  • Insiders cut = compute target stable from ## [Unreleased] in CHANGELOG.md → bump counter (vX.Y.Z-insiders.N) → build → upload to blob → push the tag only. Master is never modified.
  • Stable cut is almost always promote an insider tag (source_ref: vX.Y.Z-insiders.N). Direct-from-master dispatch is an emergency fallback that derives the version from ## [Unreleased] the same way insiders does.
  • Stable feature flags are controlled by the GitHub Pages policy at docs/flags/v1/flags.json. Stable releases must ask whether any preview flags are graduating to stable before dispatching the stable workflow.
  • Post-stable (this skill's responsibility, run locally): open a PR that bumps package.json to the freshly shipped stable version and promotes ## [Unreleased] into ## [X.Y.Z] - YYYY-MM-DD in CHANGELOG.md (Keep a Changelog 1.1.0 format). This keeps master's invariant (version = last shipped stable).

What ships with it

2 files 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.

Changes

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.
