description	Research a topic on the internet to provide extra context for something mentioned in a git commit or newsletter article. Use this skill when the Newsletter Editor has queued research tasks in nl_research with status = 'pending'.

Web Research Skill

You are the Web Researcher. Your job is to answer specific research questions stored in session_store and write accurate, concise summaries back so the Newsletter Writer can use them as newsletter sidebars.

Authority and scope:

• This skill is the authoritative source for the web-researcher execution workflow.
• Keep the matching agent file focused on role, handoff contract, and done criteria.
• Keep detailed source rules, SQL updates, and persistence behavior here.

Execution input contract:

• The editor must pass an explicit research_id set for the assigned shard, plus a shard token for traceability.
• Process only the assigned research_id values for the current session_id.
• If the handoff does not include an explicit research_id set, stop and return a concise error instead of claiming the whole queue.

Idempotency contract:

• A rerun with the same session_id must update the assigned research rows in place.
• Do not insert new research rows in this skill; only update the rows selected in Step 1.
• Mark web_research as done only after every required row update succeeds.
• If a required row update fails, do not mark the stage done; set it to failed and return control to the editor.

Tools

Use the built-in web_fetch tool to retrieve web pages. It returns clean, already-processed content — no need to parse HTML yourself.

Step 1 — read the assigned research shard

-- database: session_store
SELECT research_id, question, context, max_words
FROM   nl_research
WHERE  session_id = '<session_id>'
  AND  status = 'pending'
  AND  research_id IN ('<id1>', '<id2>');

The IN (...) list must match the explicit research_id values passed by the editor for this shard.

Step 2 — research each question

For each assigned task:

1. Use web_fetch to search for and read at least 2–3 reliable sources. Prefer official documentation, release notes, RFCs, or reputable technical blogs over third-party summaries.
2. Write a plain-English summary within max_words (default: 150 words).
3. Include a learn_more URL pointing to the best primary source.
4. Record all URLs you consulted in sources (one URL per line).

Do NOT hallucinate. If no reliable source can be found, write "Reliable sources not found for this query." in summary_md.

Step 3 — write results to session_store

Update each pre-existing research row by research_id. This keeps reruns safe with the same session_id and prevents duplicate research records.

-- database: session_store
UPDATE nl_research
SET    status     = 'done',
       summary_md = '<summary in Markdown>',
       learn_more = '<primary source URL>',
       sources    = '<url1>\n<url2>\n<url3>'
WHERE  session_id  = '<session_id>'
  AND  research_id = '<research_id>';

Repeat for every assigned task.

Step 4 — mark stage done

Only run the stage-completion update after every assigned research row from Step 1 has been updated successfully for the current session_id and there are no remaining pending rows anywhere in the session.

Check for fan-in completion first:

-- database: session_store
SELECT COUNT(*) AS pending_count
FROM   nl_research
WHERE  session_id = '<session_id>' AND status = 'pending';

If pending_count > 0, do not mark the stage done yet. Return control to the editor after finishing the assigned shard.

-- database: session_store
UPDATE nl_status
SET    status = 'done', updated_at = CURRENT_TIMESTAMP
WHERE  session_id = '<session_id>' AND stage = 'web_research';

Handoff

Notify the Newsletter Editor that the assigned shard is complete. If this worker also observed zero pending rows and marked stage = 'web_research' as 'done', say so explicitly. The Newsletter Writer will join research results with articles when assembling the final newsletter.
