Sometimes the question is not “what’s in this repo” but “what does the upstream docs page say today”. This case sends DSCC out to the web, asks it to read the Anthropic Messages API reference, and collapse the content into three tables. Permission stays read-only — the agent can fetch and summarise, but not modify files.

Capability demonstrated

• WebSearch to locate the canonical page.
• WebFetch to pull and parse it.
• StructuredOutput (or plain markdown tables) to return a consistent shape.
• ReadOnly permission mode — no local writes.

Setup

None. Any workspace works, the agent does not touch the filesystem.

Make sure your environment has outbound HTTPS and that no hook blocks WebFetch (see guides/hooks.md).

Run command

dscc --model claude-sonnet-4-6 \
  --permission-mode read-only \
  prompt "$(cat docs/cookbook/04-web-research/PROMPT.md)"

A live run against doubao-seed-2.0-code is captured at report_dscc.md / dscc_run.log.

Expected behavior

The model should typically:

1. Call WebSearch with a query like anthropic messages api reference.
2. Call WebFetch on the top hit (the docs page).
3. Possibly a second WebFetch for a linked subpage (streaming events, errors).
4. Return three markdown tables plus a source URL line.

No edit_file / write_file / bash calls.

Verification

• Output contains three tables: request body, streaming events, rate-limit headers.
• The request body table includes model, messages, max_tokens.
• The streaming table includes at least one SSE event such as message_start, content_block_delta, or message_stop.
• A source URL appears at the top.
