About the project

AI DevKit is a local-first control layer that gives multiple AI coding agents shared configuration, a terminal dashboard, cross-agent messaging, local memory retrieval, and reusable engineering workflows. It is for developers and teams supervising agents such as Claude Code, Codex CLI, Gemini CLI, OpenCode, Pi, Cursor, Copilot, or Devin. The catalogue entries are composable skills and plugin components used within that agent-management system.

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

changelog 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.

What it actually says

Changelog

Update the top Unreleased list in CHANGELOG.md from commits after the latest release.

Workflow

  1. Find the latest release base:
    • Prefer the latest reachable tag: git describe --tags --abbrev=0.
    • If there are no tags, search recent history for a release commit and use that hash.
  2. Get commits: git log <base>..HEAD --reverse --format='%H%x09%s'.
  3. Derive the GitHub repo URL from git remote get-url origin.
  4. For each commit, add one concise changelog line:
    • Format: - [<short-hash>](<url>) <one-line summary>
    • If the commit clearly relates to a PR, link the hash to the PR URL instead of the commit URL.
    • Detect PRs from subjects like (#123), merge commits, or gh pr list --search <hash> --state all --json number,url.
  5. Insert the new lines into the top Unreleased section/list in CHANGELOG.md.
    • If no Unreleased section exists, create one at the top.
    • Do not create a dated release heading unless the user asks for a release.

Rules

  • Keep one line per commit.
  • Preserve the existing changelog style when obvious.
  • Always add entries to the top Unreleased list.
  • Skip noisy commits only when clearly non-user-facing and explain what was skipped.
  • Do not invent PR links; use commit links when PR evidence is missing.
Files

What ships with it

1 file 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.
