`company_skills.markdown` stored the full SKILL.md body. The on-disk
file under `profile/skills/{companyId}/{slug}/SKILL.md` is what pi-
coding-agent actually reads via `loadSkills` at runtime. The DB column
was a duplicate — import wrote to both, renderer read from DB. Any
discrepancy between disk and DB was invisible until the agent behaved
differently from what the user saw in SkillDetail.
Disk becomes the single source of truth. DB keeps name / description /
metadata / source info / file inventory — the cheap lookup row. UI reads
SKILL.md content live via a new IPC channel.
## Migration v37 (rebuild company_skills without markdown)
Table-rebuild pattern matching v35/v36: `fn:` form, PRAGMA walk for
drift columns, row-count assertion before DROP, `defer_foreign_keys`
for the `agent_skill_assignments(skill_id)` reference. Indexes
recreated. Idempotent via `schema_migrations` ledger.
Existing DB rows' markdown content is discarded — but the on-disk
SKILL.md files are the authoritative copy, so no user-visible data
loss. Any agent using those skills keeps working; the UI just starts
reading from disk instead of the DB cache.
## Code changes
- `src/main/database/skills.ts`: drop `markdown` from read mapping,
upsert input type, INSERT column/bind list, ON CONFLICT DO UPDATE.
- `src/shared/types/records-core.ts`: `SkillRecord.markdown` removed.
- `src/main/skills/import.ts` + `import-github.ts`: drop `markdown:`
from 4 `saveCompanySkill` call sites. Disk-write via
`materializeSkillFiles` unchanged (it's what the file agent reads).
- `src/main/skills/index.ts`: expose `skillFilesDir` for the new IPC
handler to resolve `${profile}/skills/${companyId}/${slug}/SKILL.md`.
- `src/shared/contracts/channels.ts` + `schemas-execution.ts` +
`desktop-api/skills.ts`: new `getSkillMarkdown` channel
`{ companyId, slug } → DesktopResult<string>`.
- `src/preload/index.ts`: expose `getSkillMarkdown(companyId, slug)`.
- `src/main/ipc-skill-handlers.ts`: handler validates schema, ensures
company, resolves path, `readFile`, returns content. Fails closed
with `SKILL_NOT_FOUND` on ENOENT, `SKILL_READ_FAILED` on other
read errors.
- `src/renderer/components/skills/SkillDetail.tsx`: `useEffect` fetches
markdown via IPC when the skill detail loads; shows "Loading…" until
resolved, surfaces read errors. Preserves `stripFrontmatter`.
- Tests: drop `markdown:` from 2 fixture sites
(`skill-types.test.ts`, `skill-aware-assignment.spec.ts`).
## Verification
- typecheck / lint / 578 tests green
- `grep 'skill\.markdown' src/` → 0 DB-record reads
- `grep '\.markdown\b' src/main/database/skills.ts` → 0
- Remaining `.markdown` references are all `ghSkill.markdown` (GitHub
fetcher's intermediate struct feeding `materializeSkillFiles` to
disk) and parameter names in `stripFrontmatter(markdown: string)` /
fs-writer helpers — none read from a DB row.
Create src/renderer/components/ui/icons.ts as the single re-export point
for every Phosphor icon the renderer touches, then rewrite the 95 files
that previously imported directly from "@phosphor-icons/react" to pull
from the relative-path-to-barrel instead. The TitleBar commit earlier
in this series already used ui/icons; this commit extends the pattern
to the rest of the renderer.
Benefits now wired in:
- one location where bundle tree-shaking can be reasoned about,
- typos like Briefcase vs BriefCase show up against a finite list,
- re-theming or swapping icon sets is a one-file edit,
- a lint rule that flags raw @phosphor-icons/react imports can be
added later without mass-rewriting call sites.
The barrel also re-exports the `Icon` type so call sites that type
icon props against the Phosphor component type work unchanged.
Test count stays at 363 passing; typecheck stays at 156 errors.
SkillsSection had nine hardcoded English strings (header, filter
placeholder/aria-label, empty-state copy, button labels). Move them to
skills.* keys in en.ts/zh.ts and swap the component to useT().
