The full license text is at LICENSES/Apache-2.0.txt.

impeccable
Copyright (c) Paul Bakaus
https://github.com/pbakaus/impeccable
Adapted for Claude Code as the `impeccable` skill.

agent-browser
Copyright (c) Vercel Labs
https://github.com/vercel-labs/agent-browser
Adapted for Claude Code as the `agent-browser` skill.

--------------------------------------------------------------------------------

MIT-licensed work is vendored here too, and MIT requires its copyright and
permission notices travel with it. Those are in LICENSES/MIT-upstream.txt
(obra/superpowers, ehmo/platform-design-skills and garrytan/gstack) and in
claude/skills/LICENSE.pstack (pstack).

Modifications: every vendored skill was adapted for Claude Code — model names
mapped to Anthropic's, `Task` calls to the `Agent` tool, cloud-only parameters to
local execution, and frontmatter trimmed to this repo's name + description
convention. The impeccable skill vendors SKILL.md and its reference files only,
without the upstream repo's slash commands, subagents or helper scripts.


## Skill licensing

Skills under claude/skills/ carry mixed licenses depending on where they came from.
Most are ported from pstack (github.com/cursor/plugins) under MIT — see
claude/skills/LICENSE.pstack. A handful are ported from Superpowers
(github.com/obra/superpowers), also MIT; that notice and one more from
ehmo/platform-design-skills are reproduced in LICENSES/MIT-upstream.txt. Two — `impeccable` and `agent-browser` — are
ported from Apache-2.0 sources; see LICENSES/Apache-2.0.txt and NOTICE at the repo root. The
rest are original to this repo and covered by the MIT license above. See
claude/skills/ATTRIBUTION.md for the exact per-skill breakdown.
