LinkedIn Activity

Drives the user's real, logged-in Chrome session via the BYOB stack (mcp__byob__browser_*). No CDP flag, no state.json, no headless-fingerprint detection.

Default Behavior (no arguments)

Run all three tasks in order:

1. Check messages — reply to any DMs that need attention
2. Write a post — about recent work from git history
3. Browse feed — find and comment on 3 posts

If arguments are given, interpret them and do only what's asked.

Nothing goes live — post, comment, or DM reply — without passing both gates in order: first Skill('de-slop') (fresh-context review of the draft file only — removes AI-writing tells, blocks hollow drafts), then Skill('authenticity-pass'); the full gate procedures are in references/posting.md and references/feed-engagement.md.

This skill executes — it does not pause for confirmation. When the skill says "show the draft inline before publishing," that means render the draft in your response and continue with the publish step in the same turn. Don't stop to ask "should I post this?" — the user already opted in by invoking the skill, and they can interrupt mid-stream if they want changes. The only legitimate stop conditions are: (a) hard tool failure with no fallback (see the BYOB share-modal limitation in references/posting.md), (b) a finding that contradicts the skill's premise (e.g. "no DMs need replying" → skip Task 1 cleanly with one sentence of why).

Task guides (load on demand)

Each task's full procedure lives in a reference file. Load only what the current run needs:

Load...	When...
references/dom-model.md	Before the first browser_read/browser_click on any feed, post, or profile page — the byob:idx workflow and hard-won gotchas
references/messages.md	Task 1: reading the DM inbox, researching contacts, drafting and sending replies, updating the knowledge base
references/posting.md	Task 2: extracting a portable lesson from recent work, subagent drafting, persona cold-read loop, authenticity gate, publish (and the BYOB share-modal limitation)
references/feed-engagement.md	Task 3: volume targets, liking, following, comment screening, comment drafting loop, posting workflow — plus editing/deleting posted comments

Prerequisites

This skill needs two preconditions plus a scheduler-gate flag:

1. BYOB extension installed and connected

BYOB is the "Bring Your Own Browser" stack: a Chrome extension + native messaging host + MCP server that lets this skill act on the user's already logged-in Chrome (no headless profile, no per-session re-auth). Set up via /setup's computer-use opt-in or by following docs/features/byob-browser-control.md.

Verify the install in one shot:

cd ~/.byob && bun run doctor

All status lines should be green: extension loaded, native bridge running, Unix socket live. If any line is red, run /setup and answer "yes" to the computer-use opt-in to repair.

After bun run doctor passes, sanity-check that the extension is actually talking to Chrome:

mcp__byob__browser_list_tabs    # returns the user's currently open Chrome tabs

Do not proceed to LinkedIn work until browser_list_tabs returns at least one tab. An empty list or transport error means the extension isn't bound to an active Chrome window — open or focus Chrome and retry. A silent transport failure here means every subsequent BYOB call returns wrong-shaped output and the skill drives nothing.

The user must be logged into LinkedIn in that Chrome session.

2. Real-Chrome scheduler gate (requires_real_chrome=True)

LinkedIn driving real Chrome must be serialized against any other real-Chrome session — two concurrent BYOB sessions on the active tab collide and corrupt each other's DOM. PR #1277 added the AgentSession.requires_real_chrome field; the worker scheduler defers any second real-Chrome candidate until the first finishes.

There are two paths that set the flag:

• Bridge-spawned (Telegram or email): the bridge calls agent.byob_skill_triggers.infer_requires_real_chrome(message_text) before enqueue. Messages mentioning "linkedin" with first-person / intent phrasing (e.g. "check my LinkedIn DMs", "/linkedin") match a trigger and the flag is set automatically. No operator action required.

• CLI-spawned: launch with the explicit flag:

  valor-session create \
    --role eng \
    --project-key valor \
    --needs-real-chrome \
    --message "list my linkedin DMs"
  

  Always use --needs-real-chrome for any session that calls this skill. Without it, two real-Chrome sessions can race.

Tab discovery (do this first)

Always start by listing tabs and reusing an existing LinkedIn tab. Opening duplicates clutters the user's window and breaks tabId-targeted reads.

browser_list_tabs   →   look for any tab whose URL contains "linkedin.com"

Pick the first match → that's your tabId for every subsequent navigate / get_html / click / type call. If no LinkedIn tab exists, call browser_navigate(url="https://www.linkedin.com/feed/") once to open one and use the returned tabId.

The two-surface DOM model (critical)

LinkedIn has two different DOMs that need different read tools:

Surface	DOM style	Read with	Click with
Messaging (/messaging/...)	Stable, named classes (.msg-conversations-container__*, .msg-conversation-card__*)	browser_get_html(tabId, selector=".msg-*")	browser_click(tabId, selector="<stable .msg-* selector>")
Feed / Post / Profile (/feed/, /posts/..., /in/...)	Hashed/obfuscated classes (._06ad2747); BYOB injects data-byob-idx="N" on every element	browser_read(url, reuseTab=true, screens=5) → use interactiveElements	browser_click(tabId, selector="byob:idx=N") where N is from the most recent read

Why this matters: browser_read returns near-empty content on /messaging/ (LinkedIn renders that surface in a way the read pipeline can't see). browser_get_html works there because it pulls real DOM via tabId. Conversely, on the feed the hashed classes are deploy-volatile — the only stable handle is the BYOB-injected data-byob-idx, which you address as selector: "byob:idx=N".

The step-by-step byob:idx workflow and the gotcha list (scroll behavior, reuseTab, IE caps, post-body reads, tool-result overflow) live in references/dom-model.md — read it before the first feed/post/profile interaction.

Notes

• Always reuse the same tabId across a session. Discover it once at the start and pass it to every call.
• Wait 2-3s after navigation for SPA hydration — waitUntil="networkidle" mostly handles this; add browser_wait_for(selector, state="visible") for specific elements.
• Opening a message marks it as read — be aware of "seen" indicators if you don't intend to actually engage.
• Screenshots over 1MB fail — use format="jpeg" and quality=50-60 for confirmation captures.
• No fallback browser surface. BYOB is the only browser tool. If mcp__byob__browser_* calls return transport errors mid-session, run cd ~/.byob && bun run doctor in a fresh shell to repair, then retry the failed call.
