thurbox: Skill for Claude Code

.agents/skills/thurbox-release/SKILL.md

thurbox-release is a skill for Claude Code, Codex from Thurbeen/thurbox. It costs 0 tokens per session (4,046 once invoked), scanned B, original, MIT.

A guide to Thurbox's automated release pipeline and installers for supported package systems. It explains release checks, version injection, build artifacts, and publishing jobs.

In plain words
What is it for?
Use it when checking release eligibility, preparing installer artifacts, or troubleshooting Homebrew, AUR, Chocolatey, winget, and install-script publishing.
Why use it?
It makes the release decision and packaging rules predictable, including why documentation-only changes may not create a release.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is Thurbeen/thurbox's own configuration. It tells Claude Code and Codex how to work on thurbox 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 thurbox configures →

SkillSpector: 2 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 158
    Tool calls are chained to bypass individual safety checks or escalate capabilities beyond what any single tool call would allow.
    Fix: Limit tool chaining depth and validate the output of each tool before passing it to the next. Require explicit user approval for multi-step chains.
  • low Supply Chain · line 158
    Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.
    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

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 B, and why

thurbox-release scanned grade B with 2 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 12d 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.

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

How it starts

The opening of the file, as written. The whole thing — 248 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Thurbox releases, packaging and installers

Working reference indexed by AGENTS.md. The rationale behind these decisions is owned by the docs under docs/; a change that invalidates what this says updates it in the same PR.

Release Process

Releases are fully automated via GitHub Actions. No version commits are created - version is determined by git tags only.

How It Works

Every push to main automatically triggers the release workflow:

  1. Commit Analysis: Analyzes all commits since last tag using cocogitto
  2. Release Decision — a release needs both gates to pass:
    • Commit type (check-release's parse step): commits must include feat, fix, or perf. Only docs/chore/ci commits → no release.
    • Artifact relevance (check-release's shipped step): the diff since the last tag must touch something a user installs (src/, tests/, ui/, examples/, build.rs, Cargo.toml/Cargo.lock, rust-toolchain.toml, Cross.toml, extensions/, packaging/, scripts/install.{sh,ps1}, cd.yml). extensions/ and examples/panes/ are there although no binary carries them: a bare-name install resolves against the release tag, so a change never tagged is one nobody can install. ui/ and examples/lua/ are there more directly still — both are include_str!d into the binary, so they are bytes a user installs. Commit type alone over-releases: Renovate labels a GitHub-Actions pin bump fix(deps) and the website is versioned feat(ui)/fix(ui), so a CSS-only or lint-action-only change used to cut a real release (v1.2.13 through v1.3.0 were four website-only releases, one a minor) — burning a 4-platform build and pushing to the moderated Chocolatey/winget channels for a no-op binary. Such commits stay in history and ride along in the next real release's changelog.
    • The gate is evaluated over the whole span since the last tag, not the single push, so a website-only push landing on an unreleased src/ commit still cuts the release it owes. A forced workflow_dispatch version skips the relevance gate — an explicit human cut is always honoured.
  3. Automated Release (if needed):
    • Determines semantic version (feat→minor, fix/perf→patch, breaking→major)
    • Creates lightweight git tag: v{version} (e.g., v1.0.0)
    • Pushes tag to origin
    • Builds binaries for 5 targets (4 Unix .tar.gz + 1 Windows .zip; version passed via environment variable)
    • Generates changelog from commits
    • Publishes GitHub Release with binaries and release notes

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.

thurbox-release is a skill published in the GitHub repository Thurbeen/thurbox (115 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 4,046 tokens. A static security scan graded it B with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
