Depends on: comm-bridge (C4 message routing). Bundled Capability Modules (lark-cli) This skill bundles 27 capability modules under references/ , each operating against Lark via the lark-cli binary. They are not auto-loaded as top-level skills — Claude Code's skill discovery only scans top-level directories, and these sub-modules live inside this skill. The parent SKILL.md (this file) is the entry point. How to use a module : when a user's request maps to one of the modules below, Read that module's SKILL.md first to learn its exact commands/flags, then invoke lark-cli <module> ... . Prerequisites (installed automatically by zylos add lark / zylos upgrade lark — see hooks/post-install-shared.js ): lark-cli binary on PATH ( npm install -g @larksuite/cli ). 27 sub-skill folders under references/lark-*/ ( npx xc-skills add larksuite/cli ). App credentials in lark-cli's keychain ( ~/.lark-cli/config.json + AES-256-GCM encrypted file under ~/.local/share/lark-cli/ ); pushed from ~/zylos/.env automatically. Identity ( --as bot vs --as user ) : ⚠️ Prefer user identity for content operations. When querying or editing documents, wiki / knowledge bases, drive files, sheets, or Base via lark-cli, default to --as user (OAuth-authorized; 7-day rolling refresh token). The bot identity is not a member of any knowledge space and lacks drive scopes, so bot-identity content queries silently find nothing. Bot identity is appropriate for IM messaging operations. --as bot works out of the box for app/tenant-level operations (IM messaging, contacts, events). No extra login needed. --as user is the default for content operations (docs, wiki, drive, sheets, Base — see note above) and is required for surfaces tied to a real user's data (calendar, mail-write, tasks, attendance, OKR, minutes, VC-agent). The user runs lark-cli auth login --domain <name> once. On auth failure lark-cli exits with a <domain>_user_login_required error envelope; the agent should detect this and notify the owner of the login command. Module Index Path prefix for all entries: references/ Messaging & people Module Use when… lark-im/SKILL.md Send/search messages, manage groups and members, upload/download media (chunked for large files) lark-contact/SKILL.md Resolve names/emails ↔ open_ids; look up department / contact info Docs & drive Module Use when… lark-doc/SKILL.md Lark Docs v2: create / fetch / update (DocxXML or Markdown); search Drive lark-sheets/SKILL.md Spreadsheets: create, read/write cells, append rows, find lark-slides/SKILL.md Presentations: create, read, page/element ops (XML protocol) lark-markdown/SKILL.md Markdown file create / read / upload / edit lark-drive/SKILL.md Drive files & folders: upload, download, copy, move, metadata lark-wiki/SKILL.md Wiki: spaces, members, node hierarchy lark-whiteboard/SKILL.md Whiteboards: query, export preview image, DSL edits Productivity Module Use when… lark-base/SKILL.md Base (multi-dim tables): search base, tables, fields, records, views, dashboards, forms, roles lark-calendar/SKILL.md Calendar events: agenda, create, update, delete, attendees, reminders lark-task/SKILL.md Task lists, subtasks, collaborators, status lark-mail/SKILL.md Mail: draft / send / reply / forward / search; drafts, folders, labels, contacts, attachments, rules HR / workflow Module Use when… lark-approval/SKILL.md Approval instances and tasks lark-attendance/SKILL.md Personal attendance / clock-in records lark-okr/SKILL.md OKR cycles, objectives, key results, alignment, metrics Meetings & A/V Module Use when… lark-vc/SKILL.md Video conferencing history, meeting summaries (notes/todos/chapters/transcripts), participant snapshots lark-vc-agent/SKILL.md Have the bot join/leave a live meeting on the user's behalf; consume real-time events lark-minutes/SKILL.md Minutes: list, basic info, transcripts, AI summaries lark-note/SKILL.md Meeting notes (纪要): query note detail by note_id, get note_doc_token / verbatim_doc_token, read unified transcripts Apps & low-code Module Use when… lark-apps/SKILL.md Miaoda/Spark apps: create, publish HTML sites, local full-stack dev, cloud-based generation, DB ops, release management Workflows & platform Module Use when… lark-workflow-meeting-summary/SKILL.md Roll up meeting minutes over a time range lark-workflow-standup-report/SKILL.md Orchestrate calendar + task into a standup summary lark-event/SKILL.md Subscribe / consume real-time events as NDJSON streams lark-openapi-explorer/SKILL.md Discover native OpenAPI endpoints not yet wrapped by CLI shortcuts lark-skill-maker/SKILL.md Author new sub-skills wrapping lark-cli (atomic APIs or multi-step flows) lark-shared/SKILL.md Shared utilities / types referenced by other modules (rarely invoked directly) Loading Convention Before running lark-cli <module> <subcmd> : Read references/<module>/SKILL.md to confirm exact subcommands, flags, and required vs. optional args. If that module's SKILL.md references additional docs under its own references/ subdirectory, read those as well. Run the command. Skipping step 1 risks calling wrong subcommand names or missing required flags — lark-cli is feature-rich and each module covers dozens of subcommands.

Use download.js to fetch them on demand: # Download image node ~/zylos/.claude/skills/lark/scripts/download.js image <message_id> <image_key> # Download file node ~/zylos/.claude/skills/lark/scripts/download.js file <message_id> <file_key> [filename] # Examples: node ~/zylos/.claude/skills/lark/scripts/download.js image om_xxx img_v3_xxx node ~/zylos/.claude/skills/lark/scripts/download.js file om_xxx file_v3_xxx report.pdf The keys come from context messages like [image, image_key: xxx, msg_id: xxx] or [file: name.pdf, file_key: xxx, msg_id: xxx] . Output: local file path on success, error message on failure. Config Location Config: ~/zylos/components/lark/config.json Logs: ~/zylos/components/lark/logs/ Media: ~/zylos/components/lark/media/ Lark Setup 1. Credentials Add to ~/zylos/.env : LARK_APP_ID=your_app_id LARK_APP_SECRET=your_app_secret Get App ID and App Secret from your app's Credentials page: open.larksuite.com/app 2. Console Configuration In the Lark developer console ( open.larksuite.com/app ): Enable Bot capability : Add capabilities → Bot (添加应用能力 → 机器人) Subscribe to events : Event subscriptions → Add im.message.receive_v1 Set Request URL : Event subscriptions → Request URL → https://<your-domain>/lark/webhook (the path is defined by http_routes in SKILL.md) 3. Event Security Lark provides two security mechanisms for webhook events. Verification Token (REQUIRED) — validates that requests come from Lark. The service will refuse to start without it. In the console: Event subscriptions → Verification Token. Add to config: { \"bot\" : { \"verification_token\" : \"your_verification_token_from_lark\" } } Encrypt Key — encrypts event payloads using AES-256-CBC: In the console: Event subscriptions → Encrypt Key. Add to config: { \"bot\" : { \"encrypt_key\" : \"your_encrypt_key_from_lark\" } } Both can be set together: { \"bot\" : { \"verification_token\" : \"your_token\" , \"encrypt_key\" : \"your_key\" } } Cloudflare Users If your domain is behind Cloudflare proxy with Flexible SSL mode, Caddy's automatic HTTPS will cause a redirect loop. Options: Change Cloudflare SSL to Full : In Cloudflare dashboard → SSL/TLS → set mode to \"Full\" (recommended) Use HTTP mode : Run zylos config set protocol http (automatically updates Caddyfile and reloads Caddy) Owner First user to send a private message becomes the owner (primary partner). Owner bypasses DM policy and per-group/per-channel allowlist checks. However, groupPolicy: disabled blocks all group messages, including from the owner. Owner info stored in config.json: { \"owner\" : { \"bound\" : true , \"user_id\" : \"xxx\" , \"open_id\" : \"ou_xxx\" , \"name\" : \"Howard\" } } Access Control Permission Flow DM and group access are controlled by independent top-level policies: { \"dmPolicy\" : \"owner\" , // \"open\" | \"allowlist\" | \"owner\" \"dmAllowFrom\" : [ \"ou_xxx\" ] , // used when dmPolicy = \"allowlist\" \"groupPolicy\" : \"allowlist\" , // \"open\" | \"allowlist\" | \"disabled\" \"groups\" : { ... } // per-group config (used when groupPolicy = \"allowlist\") } Private DM (dmPolicy): Owner? → always allowed dmPolicy = open ? → anyone can DM dmPolicy = owner ? → only owner can DM dmPolicy = allowlist ? → check dmAllowFrom list; not in list → dropped Group message (groupPolicy): groupPolicy = disabled ? → all group messages dropped groupPolicy = open ? → respond to @mentions from any group groupPolicy = allowlist ? → only configured groups; unlisted groups → only owner passes, others dropped silently",
