description

Interact with LinkedIn — view your profile, browse other profiles, read the feed, search jobs/posts/people, get job details, create posts, like/unlike posts, comment, send connection requests, and follow/unfollow users. Use this skill whenever the user mentions LinkedIn, wants to search for jobs or people, read their LinkedIn feed, view a profile, get job details, create a post, like or comment on content, send a connection request, or follow someone. Also trigger when the user pastes a LinkedIn URL (e.g. linkedin.com/in/..., linkedin.com/jobs/view/...) or mentions LinkedIn networking.

LinkedIn

View profiles, browse the feed, search jobs/posts/people, get job details, create posts, like/unlike, comment, send connections, and follow/unfollow on LinkedIn.

Skill Directory

<SKILL_DIR> is the directory containing this SKILL.md file. Determine it ONCE at the start and reuse it.

Setup (run FIRST — every time, before any operation)

You MUST complete this setup before running any script. Do NOT skip this step.

sig status linkedin 2>&1

Check the JSON output fields configured and valid:

• configured: false → run Provider Setup below. Do NOT proceed without completing it.
• valid: false (but configured: true) → run sig login linkedin, then re-check.
• valid: true → detect proxy (see below), then execute the user's request.

Provider Setup

1. Read <SKILL_DIR>/references/provider-config.yaml
2. Append the provider block to ~/.sig/config.yaml under providers:
3. Ask the user: "Do you need a proxy to access this site?" — if yes, add networkProxy: <url> under the provider in config.yaml
4. Run sig login linkedin (with --network-proxy <url> if proxy was specified)
5. Verify: run sig status linkedin again — must show valid: true before proceeding

Proxy Detection (after provider is valid)

grep -A15 "^\s*linkedin:" ~/.sig/config.yaml | grep networkProxy | awk '{print $2}'

If this outputs a URL, prefix ALL python3 commands with HTTPS_PROXY=<url> HTTP_PROXY=<url>. If using socks5, convert to socks5h for python (e.g. socks5://... → socks5h://...). If empty, no proxy needed.

Running Scripts

All scripts require setup to be completed first (see above).

Safety

LinkedIn is a professional network. Actions taken here are visible to your professional contacts and can affect your reputation. Always confirm with the user before executing write operations:

• Creating posts — confirm the text content before publishing
• Sending connection requests — confirm the target person and optional message
• Commenting on posts — confirm the comment text before posting
• Liking/unliking — these are reversible (--undo), but still confirm first
• Following/unfollowing — these are reversible (--undo), but still confirm first

Key Concepts

Profile identifiers — linkedin_profile.py accepts a LinkedIn username (janedoe), a full profile URL (https://www.linkedin.com/in/janedoe), or an @-prefixed handle. URLs are resolved automatically.

Job identifiers — linkedin_job.py accepts a numeric job ID (12345678) or a full LinkedIn job URL (https://www.linkedin.com/jobs/view/12345678). The ID is extracted automatically.

URNs — Write operations (like, comment, connect, follow) use LinkedIn URN identifiers. Post URNs look like urn:li:activity:7100000000000000001. Profile URNs look like urn:li:fsd_profile:ACoAAA123456. You can find these in the output of read operations.

Voyager API — All operations use LinkedIn's internal Voyager API (/voyager/api/), which is the same API the LinkedIn website uses. Authentication is via JSESSIONID CSRF token and li_at session cookie.

Post search — linkedin_search_posts.py parses RSC-embedded HTML from the search results page rather than a JSON API. Results may be less structured than other endpoints.

Known Limitations

• Rate limiting — LinkedIn aggressively rate-limits API calls. The client retries once on HTTP 429 with the Retry-After delay, but sustained heavy usage may result in temporary blocks.
• Search post parsing — Post search relies on HTML scraping of RSC payloads, which may break if LinkedIn changes their frontend markup.
• No pagination for feed — The feed endpoint returns a single page of results up to the limit.
• Connection requests — Require the target's profile URN, not their username. Use linkedin_search_people.py or linkedin_profile.py to find URNs first.
• Session expiry — LinkedIn sessions typically last 30 days but may expire sooner if LinkedIn detects unusual activity.
• No media uploads — linkedin_post.py creates text-only posts. Image/video posts are not supported.

Error Handling

Error	Cause	Fix
AUTH_REQUIRED	No cookie or missing JSESSIONID	Auto-run sig login (no user prompt needed), retry
AUTH_EXPIRED	Session cookie expired (401)	Auto-run sig login (no user prompt needed), retry
NOT_FOUND	Profile or resource not found	Check the username or ID is correct
HTTP_429	Rate limited by LinkedIn	Wait and retry; reduce request frequency
HTTP_403	Forbidden or restricted	Check account status; may need re-login
