  • Topic: tool-calling — not covered in the last 14 days (only 5 topics exist so far, all posted today: local-ai, model-releases, rag, agents, coding-assistants). Last topic was local-ai, so no back-to-back repeat.
  • Articles cited: 5 (Enola, GeoSQL, OfficeCLI, FableCut, Pilotfish)
  • Why this roundup: a real through-line across five separate tool-calling releases this week — they don't make agents more autonomous, they give them narrower, deterministic APIs into specific domains (codebases, geodata, Office docs, video timelines), plus an orchestration layer about who does the calling.

Dropped after fetch attempts (couldn't read, so couldn't cite):

  • aimaker.substack.com/p/claude-code-workflow-setup and .../x-api-mcp-claude-code — both 403'd on fetch (via WebFetch and direct curl with a browser UA).
  • aiblewmymind.substack.com/p/claude-cowork-cloud-scheduled-tasks — same, 403.
  • toxsec.com/p/ciscos-agent-runtime-sdk-bakes-security — same, 403.
  • x.com/mweinbach/status/... — skipped, not a fetchable content page.
  • aidisruption.ai/p/anthropic-releases-sonnet-5 and the official anthropic.com/news/claude-sonnet-5 — not a URL dup of the existing model-releases post, but same announcement; skipped as redundant rather than adding a second angle on it.

Claims vs. API summary: no disagreements — all numbers in the post (Pilotfish's cited 96%/46% cost figure and the 58-74% community savings) came directly from the repo's README, not the API's summary field, and are attributed there as Pilotfish's own citation of an external benchmark, not something I verified independently.

Verified first-hand: cloned enola-labs/enola to confirm it's a real ~29MB Go project with dedicated extractor/linker/diff packages (not a thin LLM-prompt wrapper) — mentioned in the post. Didn't run GeoSQL, OfficeCLI, FableCut, or Pilotfish myself; said so implicitly by not claiming otherwise.

Passed bun run build locally (prerender-blog validator): 6 posts rendered, 0 contract violations.

Topic: tool-calling. 5 articles (Enola, GeoSQL, OfficeCLI, FableCut,
Pilotfish) — every one read directly, none from API summary alone.
