Tillwren is a pack of Claude Code skills, subagents and slash commands for the jobs developers repeat every week: release notes, PR descriptions, env drift, test gaps, security review, docs, SEO audits, CSV cleanup, migrations, API clients, flaky tests, dependency audits, commit splitting and bug repro. Each analysis skill first runs a small Python helper (standard library only) on your actual code, so Claude starts from facts with file and line numbers. It installs as a Claude Code plugin or as a plain .claude/ folder.
Who this is for
Developers who use Claude Code every day, freelancers and agencies shipping client projects, and small dev teams that want one shared set of skills.
What the output looks like
What the skills found in our test repo (tests/fixture.py), 9 Oct 2026
| Skill | Found | Count |
|---|---|---|
| security-pass | hard-coded token, SQL string concat, eval of request body, TLS verify off | 4 |
| env-drift | env vars read in code but missing from .env.example | 4 |
| seo-audit | page issues across 2 pages (4 HIGH) | 21 |
| test-gaps | public functions no test references | 7 |
| dep-audit | unused (lodash, flask) / undeclared (zod) packages | 3 |
How to do it
- Try the free sampler (release-notes, pr-polish, env-drift, standup).
- Buy a tier; download the zip and add it as a Claude Code plugin marketplace, or copy the .claude/ folder into your repo.
- Ask Claude Code for the chore (for example "run a security pass") or use a slash command.

Why this approach
- Starts from your real code: each analysis skill runs a helper script first, so findings come with file:line, not guesses.
- Tested before release: unit tests on the helper scripts ship in the zip, and 12 of 12 headless Claude Code scenarios passed, including a marketplace install and a plain-folder install.
- Guard-rails built in: never overwrite input, mask secrets, no force-push.
- Pro is $59 for 14 skills, 5 subagents and 4 commands; AgentKit Engineer is $99 and Agensi's 8-skill Ship-Safe Pack is $59.
- One-time price, personal and commercial use on your own and client projects.
FAQ
Does it work with my Claude Code version?
It uses the standard skills, subagents, commands and plugin formats from the Claude Code docs; any recent version with plugin support works.
Why not AgentKit?
AgentKit sells breadth: 100+ skills and 30+ workflows for $99. Tillwren sells depth for $59: 14 skills for chores you repeat every week, each with a tested helper script that reads your code first.
Why not write my own skills or use a free skills repo?
You can, and free collections are great for ideas. Tillwren saves the iteration: tested helpers, examples, guard-rails and a 14-day fix-or-refund.
Do I need Python?
Python 3.8+ and git for the helper scripts; standard library only, no pip installs.
Does it send my code anywhere?
No. The helper scripts run locally and make no network calls, except seo-audit and api-client when you give them a URL.
