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.

Instruction override

If you install

The text contains phrases like "ignore previous instructions" or "you are now…". That is an attempt to hijack the agent: it may break your rules, the system limits or company policy.

For the author

An honest skill does not need them: state the role and the rules directly without overriding other instructions. Otherwise catalog scanners and corporate filters will block the listing.

Exfiltration

If you install

The instructions or scripts send data out: environment variables, keys, file contents, chat history. You may never notice, because the agent performs the upload as "part of the task".

For the author

If the upload is not needed for the task, remove it: catalogs flag such skills and delist them. If it is needed, name the destination explicitly, say what leaves the machine, and give the user a switch.

Dangerous commands medium severity

Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.

If you install

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.

For the author

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

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.
Add a description to the frontmatter: without it the skill never triggers.
The SKILL.md body is over 5,000 tokens: move reference detail into references/ and load it when needed.

For the model run — optional

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

error frontmatter SKILL.md: no YAML frontmatter block found
error name-missing SKILL.md: frontmatter has no `name`
error description-missing SKILL.md: no `description` — the skill can never trigger
warning body-long SKILL.md body ≈ 6591 tokens (recommended < 5000); move details to references/

Process rating: all ten parameters 47/100

0Result and completion. Does not say what the result is
0When it triggers. No condition that starts the skill
0Inputs and preconditions. Does not say what the process needs to start
0Progress reporting. Says nothing while it works
60Tools and files. Uses tools (bash, web, python, node) that frontmatter does not declare
70Failures and branches. 5 branches
70Execution cost. Instruction body is 6591 tokens
85Steps. 250 steps, 1 vague phrases
100Consistency. Name and required fields are in place
100Running it twice. Mutating operations check current state

medium Safety rules and hard prohibitions inside a skill: they belong in the system prompt, here they protect nothing
low 10 top-level sections: this looks like several domains in one skill

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.

Quality signals

+5Description has no quoted example phrases that should trigger the skill
+4Description does not say when NOT to use the skill (false activations)
+3Description length 0: 120–800 characters recommended
+3Output format is not stated: the model decides each time
-226 emoji in the instructions: noise for the model
+1No license
+2Single-language instructions
+4Structure: 58 headings
+3Step-by-step instructions: 250 items
+4Has examples (31 code blocks)

Quality base 70; lint remarks subtract, signals add up to 100. Result: 0.
