jules: Skill for Claude Code

.claude/skills/watch-contacts/SKILL.md

watch-contacts is a skill for Claude Code from jonathanmalkin/jules. It costs 25 tokens per session (1,762 once invoked), scanned A, original, MIT.

A monitoring workflow for checking what selected contacts post on X, the social network formerly known as Twitter. It reads contact records, searches their posts, and identifies posts that may be worth replying to.

In plain words
What is it for?
Watching contacts and public figures, finding relevant recent posts, and reviewing possible engagement opportunities before replying.
Why use it?
It gathers updates from a contact list and avoids repeatedly surfacing posts already handled during the day. Keyword filters can narrow searches for specific contacts.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

watch-contacts scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Watch Contacts

Monitor X/Twitter activity from contacts in the network. Surface posts worth engaging with, batch reply decisions via AskUserQuestion.

Step 1: Load Contacts

Read Profiles/Contacts.md. Extract X/Twitter handles from ALL sections:

  • "Active — Following Up" table (personal contacts)
  • "X Watch List" tables (public figures, product leaders)

For each handle, also check the Filter column. If a filter string exists, that handle requires keyword-filtered search (see Step 2).

Build a handle list. Skip contacts with no X handle. Report how many handles found.

If no handles found, say so and stop.

Step 1.5: Determine Floor Timestamp (Dedup Across Runs)

Before searching contacts, check whether this skill already ran earlier today:

xurl search "from:[your-handle]" -n 20

Look at the reply timestamps. If there's a cluster of replies today (indicating an earlier watch-contacts session or manual engagement), use the end of the most recent cluster as the floor timestamp. Only surface tweets posted AFTER this floor.

  • If no earlier activity today → floor = 24 hours ago (default behavior).
  • If earlier cluster found → floor = timestamp of last reply in that cluster.
  • Report: "Last engagement session ended ~Xh ago. Filtering to tweets posted after [time]."

If the floor is very recent (< 2 hours ago), warn: "Ran recently — there may be few new posts." and proceed anyway.

Step 2: Search Recent Posts

For each handle, search for the 3 most recent tweets:

# Standard (no filter):
xurl search "from:{handle}" -n 10

# Filtered (high-volume posters — use separate queries, not OR):
xurl search "from:{handle} claude" -n 10
xurl search "from:{handle} openclaw" -n 10
xurl search "from:{handle} agent" -n 10
# Deduplicate by tweet ID across filter queries.

Filter syntax note: The X search API does not scope OR to the from: clause. from:X foo OR bar returns (from:X foo) OR (bar globally). For filtered handles, run one search per keyword and deduplicate results by tweet ID.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
