AC meta-ad-spy
Competitive intelligence skill for spying on competitor ads using Meta's Ad Library. Use this skill whenever the user wants to: research competitor Facebook/Instagram ads, analyze ad strategies, extract ad creatives or copy, find how long ads have been running, scout ad spend patterns, monitor industry advertising trends, or build any kind of competitor ad intelligence report. Triggers on phrases like "check competitor ads", "what ads is [brand] running", "spy on ads", "Facebook ad library", "Meta ad library", "scrape ads", "monitor ads", "ad intelligence", "ad research", or any request to analyze advertising strategies on Meta platforms. Always use this skill even if the user just mentions they want to understand what a competitor is doing on Facebook or Instagram.
As a process C 60/100 · Has gaps — weak spots: result and completion, inputs and preconditions, running it twice
How to improve
- The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.
- 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.

Process rating: all ten parameters 60/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 30Running it twice. 3 mutating operations with no state check
- 60Tools and files. Uses tools (python) that frontmatter does not declare
- 70When it triggers. States when to use, but not when not to
- 70Execution cost. Instruction body is 5339 tokens
- 100Steps. 30 steps
- 100Failures and branches. 2 branches, has a failure section
- 100Consistency. Name and required fields are in place
- 100Progress reporting. Reports progress
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.
