AF exa-search

Neural web search, similar-page discovery, and URL content fetching via the Exa AI search engine. USE WHEN: user asks to search the web, find articles/repos/papers on a topic, look up recent news, find pages similar to a URL, or fetch page contents for a known URL. NOT FOR: fetching tweets (use fxtwitter), downloading videos (use yt-dlp), scraping JS-heavy or anti-bot sites (use scrapling), querying APIs directly, or searching local files/repos (use rg/find).

How to improve

  1. The text references files that are not there: add them or drop the references.
For the model run — optional
  • Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
  • A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec

  • warning missing-ref reference to a missing file: url
  • note frontmatter-key unknown frontmatter key "homepage"

Process rating: all ten parameters 50/100

Will not run. References files that are not bundled: url
  • 0Tools and files. 1 referenced file(s) missing: url
  • 0Progress reporting. Says nothing while it works
  • 30Running it twice. 2 mutating operations with no state check
  • 40Consistency. Frontmatter name (exa-search) differs from the folder (exa-search-rust)
  • 50When it triggers. No condition that starts the skill
  • 50Failures and branches. 0 branches, has a failure section
  • 60Result and completion. Output format stated, no completion criterion
  • 70Inputs and preconditions. Inputs and preconditions are listed
  • 85Steps. 18 steps, 1 vague phrases
  • 100Execution cost. Instruction body is 1731 tokens
  • medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
  • low 10 top-level sections: this looks like several domains in one skill

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
