name	docs-sync
description	Keep ioredis documentation synchronized with code behavior. Use when an agent changes public APIs, options, Redis command support, examples, generated typings, connection behavior, Cluster/Sentinel behavior, Pub/Sub, pipelines, transactions, scan streams, reconnect behavior, TypeScript usage, or release-facing behavior that may require README or docs updates.

Docs Sync

Use this skill to decide whether an ioredis change needs documentation, update the right docs, and keep examples aligned with tested behavior.

For broad documentation audits, option/API coverage checks, or unclear documentation scope, also read references/doc-coverage-checklist.md before deciding what to update.

Workflow

1. Inspect the changed behavior.

   • Read the diff and the surrounding implementation.
   • Identify whether users must know a new capability, option, error case, event, command signature, return shape, or migration concern.
   • Treat TypeScript declarations and public JSDoc as documentation when command signatures, constructor options, or exported types change.

2. Find the documentation surface.

   • README.md: primary user-facing guide, examples, feature overview, options, and common workflows.
   • lib/redis/RedisOptions.ts: RedisOptions, CommonRedisOptions, option JSDoc, and DEFAULT_REDIS_OPTIONS.
   • lib/cluster/ClusterOptions.ts: ClusterOptions, cluster option JSDoc, and DEFAULT_CLUSTER_OPTIONS.
   • lib/connectors/StandaloneConnector.ts and lib/connectors/SentinelConnector/types.ts: connection option types that contribute to public constructor options.
   • docs/: generated TypeDoc output from public source comments.
   • examples/: runnable snippets that should match current API behavior.
   • lib/index.ts and public TypeDoc comments: exported API documentation surface.
   • test/typing/: executable documentation for TypeScript signatures.

3. Update docs when the change affects users.

   • Public option or constructor behavior: document option name, default, behavior, topology limitations, and Redis version constraints in JSDoc first; update README/examples when users need prose or usage guidance.
   • Redis command support: update generator config in bin/, regenerate lib/utils/RedisCommander.ts, and document only if README/docs mention related command groups or if the change affects command typing, return mapping, or examples.
   • Pub/Sub, sharded Pub/Sub, monitor, pipeline, transaction, Sentinel, Cluster, TLS, reconnect, or offline queue behavior: update the relevant README/docs section.
   • New or changed public exports from lib/index.ts: update TypeDoc comments and typing tests when the exported type or class is part of the supported API.
   • Breaking or compatibility-sensitive behavior: add explicit migration or caveat wording.
   • Internal-only refactors with no behavioral/API impact: state that no docs update is needed and why.

4. Keep examples honest.

   • Prefer short examples that compile against the current public API.
   • Avoid documenting behavior that is not covered by tests unless you also add or request coverage.
   • If an example requires a Redis version, topology, or protocol mode, say so near the example.
   • Use existing README style and terminology.

5. Verify documentation changes.

   • For TypeScript examples or declarations, run the focused tsd test or add one when appropriate.
   • For API docs comments, run npm run docs when the change affects generated docs.
   • For command typing changes, run node bin/index.js before validating generated typings.
   • For Markdown-only edits, inspect nearby formatting and links; run npm run format-check only when relevant files are covered by Prettier.

Documentation Decision Checklist

• Does the change alter public exports from lib/index.ts?
• Does it add, remove, rename, or change JSDoc/defaults for RedisOptions, CommonRedisOptions, ClusterOptions, standalone connection options, or Sentinel connection options?
• Does it add, remove, or change a Redis command method signature?
• Does it change reply transformation, Buffer variants, callbacks, or Promise behavior?
• Does it affect connection lifecycle, retries, ready checks, offline queue, or subscriber mode?
• Does it affect Cluster routing, redirections, subscriber groups, Sentinel discovery, or TLS?
• Does it add an option, event, error condition, or environment assumption?
• Would a user need different code after this change?

If any answer is yes, update docs or explicitly explain why existing docs already cover it.
