BC deno-deploy
Deploy simple web pages and HTML apps live to the internet using the Deno Deploy REST API. Use this skill whenever the user wants to make something "live", "hosted", "shareable via URL", "deployed", or "accessible online" — even if they don't mention Deno explicitly. Also trigger when the user asks to build a web page, interactive app, or HTML project that would benefit from a live URL. Does not require the Deno MCP tool — this skill is fully standalone and uses the Deno API directly.
As a process C 60/100 · Has gaps — weak spots: result and completion, inputs and preconditions, consistency
What is at stake
The skill contains fragments that, in the wrong hands, cost money or data. Below: what the installer risks and what the author should do.
The skill tells the agent to hide things from you: not to show errors, not to mention actions, to report differently from what was done. You lose the ability to see what the agent really did.
Transparency beats a smooth answer. If the goal is to hide technical noise, ask the agent to "summarise briefly", not to "not mention".
How to improve
- Address the high-severity findings: each costs 18 safety points. If one is a false positive, add the rule id to guard.allow in spec.yaml.
- 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. 22 mutating operations with no state check
- 40Consistency. Frontmatter name (deno-deploy) differs from the folder (deno-subhosting-deploy-skill)
- 60Tools and files. Uses tools (web, python) that frontmatter does not declare

- 100Execution cost. Instruction body is 1261 tokens
- 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.
