LinkedIn: Create Posts (and Engage Safely)

When to Activate

User asks to create a LinkedIn post (text, image, document, link/article)
User asks to polish/draft a LinkedIn post in a professional tone
User asks to post as themselves vs as a company page
User asks to react/comment on a LinkedIn post, or review comments

Tools

Primary custom tools

LINKEDIN_CUSTOM_CREATE_POST - preferred post creation (text/image/carousel/document/article)
LINKEDIN_CUSTOM_ADD_COMMENT - add comment to a post URN
LINKEDIN_CUSTOM_GET_POST_COMMENTS - fetch comments for a post URN
LINKEDIN_CUSTOM_REACT_TO_POST - react to a post URN
LINKEDIN_CUSTOM_GET_POST_REACTIONS - fetch reactions for a post URN
LINKEDIN_CUSTOM_DELETE_REACTION - remove your reaction from a post URN

Context + identity tools

LINKEDIN_GET_MY_INFO - authenticated person identity context
LINKEDIN_GET_COMPANY_INFO - organization context for company posting
LINKEDIN_GET_POST_CONTENT - read/verify post content before engagement

Toolkit fallback tools

Use these when a custom tool does not fit the request:

LINKEDIN_CREATE_LINKED_IN_POST - generic fallback post creation
LINKEDIN_CREATE_ARTICLE_OR_URL_SHARE - fallback for URL/article share flows
LINKEDIN_CREATE_COMMENT_ON_POST - fallback comment creation
LINKEDIN_LIST_REACTIONS - fallback reactions listing
LINKEDIN_DELETE_POST / LINKEDIN_DELETE_LINKED_IN_POST / LINKEDIN_DELETE_UGC_POST / LINKEDIN_DELETE_UGC_POSTS - deletion tools (explicit consent required)

Composio fallback tools may require explicit author URNs:

Person author: urn:li:person:<person_id> (resolve via LINKEDIN_GET_MY_INFO)
Organization author: urn:li:organization:<org_id> (resolve via LINKEDIN_GET_COMPANY_INFO)

Professional Standard (Non-Negotiable)

Maintain a professional, business-appropriate tone.
Avoid slang, profanity, and overly casual language.
Do not fabricate achievements, metrics, titles, affiliations, or outcomes.
Prefer clarity over cleverness; use short paragraphs and readable formatting.
Avoid emojis unless the user explicitly uses them or requests them.

Draft-First Rule (Critical)

For creating posts:

Draft the post copy first and show it to the user.
Ask for explicit confirmation to post (e.g., "Post it", "Yes, publish", "Go ahead").
Only then call the chosen post-creation tool.

Do not publish on the user's behalf without explicit confirmation.

Step 1: Determine Author and Goal

Collect (or infer from context) the minimum:

Objective: announce / educate / hiring / launch / learnings / personal update
Audience: customers / peers / recruiters / founders / internal team
Voice: confident / humble / informative / celebratory
Call-to-action: comment / DM / link click / hiring applications
Post as: me vs company page

If author context matters, call:

LINKEDIN_GET_MY_INFO
If posting as a company, LINKEDIN_GET_COMPANY_INFO

Step 2: Choose Post Type and Required Inputs

Prefer LINKEDIN_CUSTOM_CREATE_POST for all post types.

Text-only: commentary only
Image post: commentary + image_url (or image_urls for carousel; supported, max 20)
Document post: commentary + document_url + document_title
Link/article post: commentary + article_url

Fallbacks when needed:

LINKEDIN_CREATE_ARTICLE_OR_URL_SHARE for URL/article specific share flows
LINKEDIN_CREATE_LINKED_IN_POST for generic toolkit creation flows

Custom post tool handles media uploads.

Step 3: Draft the Post Copy

Recommended structure:

Hook (1-2 lines)
Value (2-5 short paragraphs or bullets)
Credible details (only true, verifiable)
CTA (one clear action)

Formatting rules:

Use whitespace; avoid dense blocks.
Use bullets sparingly (3-7 max).
Use 0-3 hashtags unless the user asks for more.

Step 4: Create the Post

Examples (shape; adjust to actual tool schema):

# Text-only
LINKEDIN_CUSTOM_CREATE_POST(commentary="...", visibility="PUBLIC")

# Image
LINKEDIN_CUSTOM_CREATE_POST(commentary="...", image_url="https://...", visibility="PUBLIC")

# Document
LINKEDIN_CUSTOM_CREATE_POST(
  commentary="...",
  document_url="https://...",
  document_title="...",
  visibility="PUBLIC",
)

# Link/article
LINKEDIN_CUSTOM_CREATE_POST(commentary="...", article_url="https://...", visibility="PUBLIC")

# Post as an organization
LINKEDIN_CUSTOM_CREATE_POST(
  commentary="...",
  organization_id="urn:li:organization:12345",
  visibility="PUBLIC",
)

# Toolkit fallback for URL/article shares
LINKEDIN_CREATE_ARTICLE_OR_URL_SHARE(...)

# Toolkit fallback for generic post creation
LINKEDIN_CREATE_LINKED_IN_POST(...)

Return the post URL and the returned post URN. Note: the tool returns post_id as the post URN; use it as post_urn for comments/reactions.

Engagement Guidance

Add reaction: LINKEDIN_CUSTOM_REACT_TO_POST
Remove reaction: LINKEDIN_CUSTOM_DELETE_REACTION (only after explicit user confirmation)
