CC did-my-message-go-out
Did my message actually go out? Was it delivered, or did the send only look successful? Use this after any message send whose delivery matters — a notification, a reply the user is waiting for, a forward to another chat — and before telling the user it was sent. Cross-checks the runtime's send result (message_sent success/error) against the wire: the request this process made to the channel API (api.telegram.org, discord.com, slack.com, graph.facebook.com, api.twilio.com, graph.microsoft.com) and its status code. Returns exactly DELIVERED, NOT_DELIVERED, CLAIMED_ONLY, CANCELLED, PENDING or NO_SEND. Do not use to confirm channels that deliver outside this process (WhatsApp Web, Signal, iMessage); for those it tells you the wire cannot confirm and what to do instead.
Did my message actually go out?
As a process C 62/100 · Has gaps — weak spots: inputs and preconditions, running it twice
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 62/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 30Running it twice. 13 mutating operations with no state check
- 50When it triggers. No condition that starts the skill
- 50Failures and branches. 0 branches, has a failure section
- 60Tools and files. Uses tools (bash) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 100Steps. 31 steps
- 100Consistency. Name and required fields are in place
- 100Execution cost. Instruction body is 1318 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.
