joshuashepherd Skill Docs Type Safety 2Audit and update the type safety documentation in _docs/type/ to match the actual codebase state. Ensures docs are the single source of truth without errors or gaps.

joshuashepherd Skill Fragmentation Story 2Tell a named movement leader's actual story of informational and relational fragmentation. Inventories every place their content currently lives — books, PDFs, articles, blogs, websites, social media, their own head, notes/laptop, apps, podcasts, YouTube, sermons, talks — with specific titles and locations pulled from prior research. Use when asked to map fragmentation for a leader, audit where their content is scattered, or produce a "where does it all live" report. Reads from `docs/movement_leader_research/{slug}/` and writes `fragmentation-story.md` into that leader's folder.

testdouble Bundle Tdd 2Write code through a disciplined, BDD-framed Test-Driven Development loop: build a behavior test list, then drive each behavior through red-green-refactor with an enforced observed-failure gate. Use when the user wants to implement, build, or write code test-first, "do TDD", follow "red-green-refactor", drive code from tests, choose the next test by the Transformation Priority Premise (TPP) or ZOMBIES ordering, or grow a feature behavior-by-behavior with tests leading. This skill writes and changes code; it does not produce a test plan document (use automated-test-planning, or manual-test-planning for a plan a person runs by hand), review or audit existing code (use code-review), restructure existing code outside a TDD loop (use refactor, or plan-a-change to plan a multi-module restructure), specify what a feature should do (use plan-a-feature), or find the root cause of a bug (use investigate). Runs its loop to completion without pausing for review; to review each behavior as it lands, use pairing.

testdouble Bundle Code Review 2Run a comprehensive code review on local source files. Use this skill when the user asks to review, audit, inspect, evaluate, or check code, even if they never use the word "review." Does not post comments to GitHub pull requests — use post-code-review-to-pr for that. Does not analyze architectural structure or module boundaries — use architectural-analysis for that. Does not explain code or a PR to build understanding before reviewing — use code-overview for a written overview, or code-walkthrough to be paced through it one step at a time. Does not map bounded contexts or domain boundaries — use ddd-analysis for that. Does not capture feedback on Han's own skills — use han-feedback for that.
218 -
testdouble Bundle Automated Test Planning 2Produce a standalone test plan by analyzing code for test coverage gaps and edge cases. Use when you need to create, generate, or draft a test plan for a branch, need to analyze test coverage, or need to identify what tests to write for specific files or directories. Does not produce a plain-language plan for a person to run tests by hand — use manual-test-planning for that. Does not write test code — use tdd to implement behavior test-first. Does not refine existing plans — use iterative-plan-review. Does not review code quality, security, or style — use code-review for full code review. Does not evaluate architectural testability or structural coupling — use architectural-analysis for architectural assessment.

kanevry Skill Hook Development 2Use when creating, modifying, or debugging Claude Code hooks — PreToolUse, PostToolUse, Stop, SubagentStop, SessionStart, SessionEnd, UserPromptSubmit, PreCompact, Notification. Covers the plugin `hooks/hooks.json` wrapper format vs. the user `settings.json` direct format, matchers, security patterns, `$CLAUDE_PLUGIN_ROOT` portability, lifecycle limitations, and debugging. Trigger on "add a hook", "validate tool use", "block dangerous commands", "enforce completion", "hook-based automation".

rulebase-co Skill Cx Regulatory Reporting PackUse to assemble a pack of support evidence for a regulator, auditor or supervisory request, at the standard of reproducibility those audiences apply. Trigger for "the regulator has asked for", "prepare an audit pack", "evidence request from compliance", supervisory information request, s166-style review support, or assembling complaint and QA evidence for an external body.
1 -
rulebase-co Skill Cx Peer Review DesignUse to design peer or self-review QA programmes that complement — not replace — audit QA, with clear purpose, bias controls, and separate reporting. Trigger for "peer review programme", "agents reviewing each other", "self-QA", "peer QA vs central QA team", when peer review helps culture vs when it substitutes for audit, or bias risks in peer scoring.
1 -
rulebase-co Skill Cx Contact Driver TaxonomyUse to design, rebuild, or audit a support contact taxonomy — the categories that record why customers contact. Trigger for "build a contact reason taxonomy", "our ticket categories are useless", "too many tickets are tagged Other", contact driver analysis, ticket categorisation or tagging schema, reducing contact volume, or deciding what to fix from support data.
1 -
rulebase-co Skill Cx Rubric False Positive AuditUse when a QA team says the scorecard is too harsh or produces too many false positives, to find which criteria are actually misfiring and fix those rather than lowering the bar everywhere. Trigger for "our evaluation scores keep tanking", "there are too many false positives", "how can we be more lenient", "what exceptions do I need to add to the scorecard", agents disputing evaluations, or a scorecard nobody trusts any more.
