* docs: plan a CLAUDE.md and Skills for the repo's recurring workflows (#443) Audits what the repo already documents well (README, docs/handlers.md, docs/forms.md, the per-folder eslint import bans) against what is written down nowhere — the codegen prerequisite that makes apps/api uncompilable on a fresh clone, the four stale root-level plans describing the removed controllers layer, the Makefile's wrong MIGRATIONS_DIR default, and the barrel/test/story siblings every slice is expected to carry. Proposes a root CLAUDE.md plus one per area (libs/ui, apps/api) so frontend rules are not paid for by Go-only sessions, and six Skills for the workflows the file counts show are templated: verify, ui-feature-slice, api-endpoint, db-migration, write-spec, docs-site-page, e2e-spec. Phases are sized one per PR. No application code is touched. Claude-Session: https://claude.ai/code/session_01VM4BAxzahdoj9mzpEGRaYQ Co-authored-by: Claude <noreply@anthropic.com> * docs: rewrite root CLAUDE.md as a rule sheet and index (#444) Implements Phase 1 of docs/plan-claude-md-and-skills.md: keeps the existing comment rule verbatim and first, then adds the traps an agent otherwise rediscovers by trial and error (the gitignored Go codegen prerequisite, the four stale root-level planning docs), a summary of the ESLint-enforced layer boundaries with the eslintrc as authority, the conventions lint can't catch (usecase FSMs, barrel exports, *domain.Error, mockgen, migration gotchas), and a doc index. No prose duplicated from README.md; every link resolves. Claude-Session: https://claude.ai/code/session_012qMpjsE9bwgZvWngdWkNhs Co-authored-by: Claude <noreply@anthropic.com> * docs: add libs/ui CLAUDE.md for frontend slice rules (#445) Phase 2 of docs/plan-claude-md-and-skills.md: the FSM use case shape, handler/form/screen boundaries with their authoritative docs, barrel discipline, and the test-harness gotchas that lint cannot catch. Claude-Session: https://claude.ai/code/session_011QausgGEHDtqAXUR1p2XGf Co-authored-by: Claude <noreply@anthropic.com> * docs: add apps/api/CLAUDE.md for backend slice rules (phase 3) (#446) Adds the backend area rules file from docs/plan-claude-md-and-skills.md phase 3: the domain/data/presentation file shape per feature, the *domain.Error contract, public-vs-authenticated routing, and the migrations/MIGRATIONS_DIR trap, each cited to its authority in the repo. Claude-Session: https://claude.ai/code/session_011y6QEDeaJ4m2XyhcjYsHUu Co-authored-by: Claude <noreply@anthropic.com> * docs: add verify skill for choosing the narrow test/lint command (phase 4) (#447) Adds the verify skill from docs/plan-claude-md-and-skills.md phase 4: a what-changed to command table, the api-contract codegen prerequisite, single-file test loops, and what pr-test.yml/e2e-main.yml will and will not catch before merge. Claude-Session: https://claude.ai/code/session_01H1vxxZZ2mXWVEgsGqzGXyM Co-authored-by: Claude <noreply@anthropic.com> * docs: add ui-feature-slice skill for frontend slice template (phase 5) (#448) Documents the file set, FSM use-case skeleton, handler/form/screen rules, composition root shape, and test pattern for adding a frontend feature slice in libs/ui, using the Budget slice as the verified reference example.

Claude-Session: https://claude.ai/code/session_019PubCtkZbjkU1fSShMVCKn Co-authored-by: Claude <noreply@anthropic.com> * docs: add write-spec skill for PRD/TRD/plan authoring (#451) Phase 8 of docs/plan-claude-md-and-skills.md: documents the docs/ house style (PRD vs TRD vs plan, D-numbered decisions, one-phase-per-PR sizing) so specs stay consistent and their decision numbers stay stable. Claude-Session: https://claude.ai/code/session_01Pjw1aXnLk2WBXqtEEDLGQj Co-authored-by: Claude <noreply@anthropic.com> * docs: add docs-site-page skill for VitePress feature pages (phase 9) (#452) Phase 9 of docs/plan-claude-md-and-skills.md: documents where a feature page and its screenshots/diagrams belong, and the sidebar-wiring step in .vitepress/config.ts that has no error when skipped, leaving a page built but unreachable. Claude-Session: https://claude.ai/code/session_01Asbozcv2zvRwh5csDDNgcp Co-authored-by: Claude <noreply@anthropic.com> * skill: add e2e-spec for Playwright e2e coverage in pos-web-e2e/order-web-e2e (#453) Phase 10 of docs/plan-claude-md-and-skills.md (S7). Documents where specs live, the seeded environment and pre-baked auth CI assumes, the testMatch/testIgnore routing for no-auth and mobile projects, the DOKU stub flow, and why the suite must be run green locally since pr-test.yml never runs it.
