-## Required Skills
-
-Always use the following agent skills when working in this repository. These skills contain the canonical API references and must be consulted to ensure documentation accuracy.
-
-### CipherStash Product Skills
-
-Use these skills whenever writing or editing documentation about the corresponding product area. They contain the complete, up-to-date API surface, code examples, and type signatures.
-
-| Skill | Use when editing docs in |
-|---|---|
-| `encryption` | `content/docs/encryption/` — Schema definition, encrypt/decrypt, searchable encryption, bulk operations, identity-aware encryption, error handling, migration |
-| `secrets` | `content/docs/secrets/` — Secrets SDK (`set`/`get`/`getMany`/`list`/`delete`), `stash` CLI usage, environment isolation |
-| `drizzle` | `content/docs/encryption/drizzle.mdx` — `encryptedType` column, `extractEncryptionSchema`, `createEncryptionOperators`, encrypted query operators, batched and/or, EQL migrations |
-| `supabase` | `content/docs/encryption/supabase.mdx` — `encryptedSupabase` wrapper, transparent encrypt/decrypt on insert/update/select, query filters (eq, like, gt, in, or, match), identity-aware encryption |
-| `dynamodb` | `content/docs/encryption/dynamodb.mdx` — `encryptedDynamoDB` helper, `__source`/`__hmac` attribute naming, encrypted partition/sort keys, bulk operations, audit logging |
-
-### Documentation Update Skill
-
-Use the `update-docs` skill whenever:
-- Creating new documentation pages
-- Updating existing documentation based on code changes
-- Reviewing documentation completeness for a PR
-- Scaffolding docs for a new feature
-
-The `update-docs` skill enforces the following workflow:
-
-1. **Analyze changes** — Diff the branch to identify affected files
-2. **Map to docs** — Use the code-to-docs mapping to find which MDX files need updates
-3. **Review each doc** — Walk through updates with user confirmation before editing
-4. **Validate** — Run `bun run lint` to check formatting
-5. **Commit** — Stage documentation changes
-
-#### Documentation Validation Checklist
-
-Before committing documentation changes, verify:
-
-- Frontmatter has `title` and `description`
-- Code blocks have `filename` attribute
-- TypeScript examples come first, with `switcher` and a JS variant where appropriate
-- Props/options tables are properly formatted
-- Notes use the `> **Good to know**:` callout pattern
-- `bun run lint` passes
