AC fb-personal-poster
Post text and photos to personal Facebook timeline using browser automation (Patchright/Playwright). Use when: user asks to post to personal Facebook, publish to FB personal profile, upload photos to FB timeline, or share content on their personal Facebook wall. NOT for Facebook Pages (use fb-page-poster or Graph API instead). CREDENTIALS REQUIRED: FB_COOKIE_FILE (Facebook session cookies JSON — treat as password), FB_STATE_FILE (Playwright state path, writable).
As a process C 64/100 · Has gaps — weak spots: result and completion, failures and branches, running it twice
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.

Process rating: all ten parameters 64/100
- 0Result and completion. Does not say what the result is
- 0Failures and branches. Linear process with no failure handling
- 30Running it twice. 3 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 70Inputs and preconditions. Inputs and preconditions are listed
- 100Tools and files. No external tools needed
- 100Steps. 10 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 661 tokens
- 100Progress reporting. Reports progress
- 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.
