Claude Skills by matthewsinclair

Ash Framework database-access rules: domain code interfaces, actor on query/changeset

Session forensics: analyzes Claude Code sessions against memory rules, finds gaps and enforcement failures

Cost analysis: estimates development cost of reproducing a codebase from scratch

Systematic debugging: 4-phase process with 3-strike architectural review

Detrope: diagnoses LLM writing tropes and stylometric tells, assesses in project context, shows remediation plan

Elixir coding rules: pattern matching, tagged tuples, with-railways, @impl true, Highlander

Elixir testing rules: strong assertions, no control flow in tests, async by default, real code over mocks, Highlander for tests

Core Intent workflow rules for steel threads, agents, treeindex, and session management

Session finish: update ST docs, wip.md, restart.md, commit cleanly

Session handoff: generate handoff doc for future sessions

Next step: review state, identify smallest coherent work unit, wait for go

Phoenix LiveView rules: two-phase mount, streams for lists, thin LiveViews, @impl true on callbacks

Planning kickoff: show workplan, invoke coding skills, enforce rules before coding

Two-stage code review: spec compliance then rule-library compliance via critic-<lang>

Session bootstrap: auto-load coding skills for the detected project language after context reset or compact

Coding standards: agnostic principles (Highlander, PFIC, Thin Coordinator, No Silent Errors) + project rules

Session start: read restart files, review STs, orientation overview before coding

TCA audit: execute component audits with sub-agents, track progress, manage context

TCA finish: final verification, ST doc updates, feedback report generation, and session wrap-up

TCA init: provision steel thread, rule set, component map, and work packages for a Total Codebase Audit

TCA remediate: execute prioritized fix batches in main conversation with compile/test gates

TCA synthesize: cross-component deduplication, priority classification, and fix batch ordering

Verification gate: require fresh evidence before any completion claim

Multi-session coordination via intent/whiteboard/: claim ST scopes, signal cross-stream, heartbeat, release on session end
