AC tella
Manage Tella via CLI - videos, clips, playlists, webhooks. Use when user mentions 'tella', 'tella.tv', 'tella video', 'screen recording', 'video transcript', 'clip thumbnail', 'video export', 'remove filler words', 'add zoom to video', 'blur video', 'highlight video', 'playlist of videos', or wants to interact with the Tella video recording/editing API.
As a process C 57/100 · Has gaps — weak spots: when it triggers, inputs and preconditions, consistency
What is at stake
Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
The skill contains commands that delete files, rewrite disks or execute code fetched from the network. The agent may run them without asking if it believes the instructions require it.
Replace destructive commands with safe equivalents that ask for confirmation, scope them to one folder, and stop piping curl into a shell: pin a version and a checksum.
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 57/100
- 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. 37 mutating operations with no state check
- 40Consistency. Frontmatter name (tella) differs from the folder (tella-cli)
- 60Tools and files. Uses tools (bash, web) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 100Steps. 29 steps
- 100Failures and branches. 1 branches, has a failure section
- 100Execution cost. Instruction body is 2344 tokens
- low 10 top-level sections: this looks like several domains in one skill
- low The response is described with custom markup (78 tags): a typed call is more reliable
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.
