BC meta-business
Meta Business Suite automation via Graph API. Use this skill when: (1) Publishing posts to Facebook Pages (2) Scheduling Facebook posts (3) Publishing to Instagram (photos, reels, carousels) (4) Reading insights/analytics from Facebook or Instagram (5) Managing comments on Facebook or Instagram (6) Uploading photos or videos to Facebook Pages (7) Deleting posts from Facebook or Instagram
As a process C 51/100 · Has gaps — weak spots: result and completion, when it triggers, inputs and preconditions
How to improve
- 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
- note
frontmatter-keyunknown frontmatter key "homepage"
Process rating: all ten parameters 51/100
- 0Result and completion. Does not say what the result is
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Progress reporting. Says nothing while it works
- 20When it triggers. No condition that starts the skill
- 30Running it twice. 7 mutating operations with no state check
- 40Consistency. Frontmatter name (meta-business) differs from the folder (meta-business-suite)
- 55Failures and branches. 1 branches
- 100Tools and files. No external tools needed
- 100Steps. 15 steps
- 100Execution cost. Instruction body is 2013 tokens
- medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
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.
