+    it does not execute skill code at install time (skills are prompt
+    workflows loaded on demand)."
+  - The download archive is generated by GitHub from the repository branch and
+    contains the same markdown sources as the repository tree.
+privacyNotes:
+  - When invoked by the agent, skills read and operate on the user's local
+    repository (diffs, source files, commit messages) to perform review,
+    debugging, and test generation; all processing stays inside the user's own
+    agent session.
+  - The pack collects no telemetry, requires no credentials or API keys, and
+    sends no data to any third-party service.

+# Claude Skills Pro
+
+Claude Skills Pro is a pack of fifteen engineering-workflow skills written in
+the open `SKILL.md` format. Each skill encodes one staff-engineer workflow as
+a numbered procedure with an output contract and hard anti-patterns, so agents
+follow the workflow instead of paraphrasing it.
+
+Seven of the fifteen are free and MIT-licensed in the same repository:
+
+- `pr-reviewer` runs a 7-dimension review sweep and reports findings as
+  blocker / should-fix / nit with `file:line`, never a rubber stamp.
+- `bug-hunter` forces reproduce → bisect → single hypothesis → minimal fix →
+  regression test; shotgun patching is explicitly banned.
+- `test-forge` generates boundary-value and failure-path tests, then runs a
+  mutation self-check — tests that cannot kill mutants are not done.
+- `feature-spec` produces a one-page spec (scope, non-goals, contracts,
+  edge-case table, test scenarios) before any code is written.
+- `commit-craft` splits tangled changes into logical commits, scans for leaked
+  secrets, and writes messages that explain why.
+- `changelog-release` derives the semver bump from actual contract changes and
+  writes release notes for the consumer, not the commit log.
+- `ai-code-reviewer` reviews AI-written code against its defect profile —
+  hallucinated APIs, plausible-but-wrong logic, silent behavior drift,
+  invented requirements — and never grades on style.
+
+The remaining eight (security audit, behavior-preserving refactor, perf
+profiling, safe database migration, codebase onboarding, API design,
+dependency upgrades, legacy-code explanation) ship in a paid Pro pack with an
+11-chapter Chinese handbook.
+
+## Knowledge Freshness
+
+The skill set and the free/pro split can change with releases. This entry was
+verified on **2026-09-01**; prefer the live repository for current counts:

+## Retrieval Sources
+
+- Repository: https://github.com/Hahaknight/claude-skills-pro
+- Landing page: https://hahaknight.github.io/claude-skills-pro
+- Install command: `npx skills add Hahaknight/claude-skills-pro`
+
+## Core Workflow
+
+Install pulls the seven free skills into the agent's skills directory. After
+that the skills trigger on intent: "review this diff" loads `pr-reviewer`,
+"investigate this bug" loads `bug-hunter`, "add tests" loads `test-forge`.
+The frontmatter `description` is written as a trigger surface (what it does +
+MUST USE when + the exact words users say), which is what makes the skills
+fire reliably rather than sleep.
+
+## Capability Scope
+
+Covers the daily engineering loop: spec → implement → test → review → commit
+→ release, plus debugging, onboarding to unfamiliar codebases, refactoring,
+performance work, database migrations, dependency upgrades, and auditing
+AI-generated code.
+
+## Compatibility
+
+### Native
+
+- Claude Code
+
+### Runtime Providers
+
+Any SKILL.md-compatible agent via the vercel-labs/skills installer, including
+Codex, Gemini CLI, Qwen Code, goose, crush, Cursor, opencode and 75+ others.
+The Gemini CLI, goose, and crush install paths have been verified end-to-end
+by the author.
+
+## Production Rules
+
+- The seven free skills are standalone and MIT-licensed; no attribution
+  beyond the license is required.
+- Skills are text workflows — they do not execute code on install and carry no
+  credentials.
+- Review skills are advisory: findings must be read by a human before
+  merging; the pack never auto-approves.
+
+## License and Disclosure
+
+Free skills: MIT. This entry was submitted by the repository author
+(Hahaknight); the seven free skills can be used without any purchase, and the
+description above reflects the repository as of 2026-09-01.
