Agent skill for sandbox - invoke with $agent-sandbox

The skillemall take

Claims to set up an isolated sandbox environment for agent experiments. Contains one 753-token module, no scripts, no critical errors. Quality score 65 and process score 41 signal sloppy documentation: the logic exists, but execution is rough. No model runs, no deployed sandbox. Safety checks pass (score 100), but that doesn't offset incomplete implementation.

Skip it. The skill works as a draft: files are clean, but undertested. If you need a Claude, Cursor, or Gemini sandbox to build on—take it and finish the job yourself. If you want something production-ready, wait for an update.

How to improve

  1. Say in the description WHEN to use the skill ("use when…", example requests): that is the agent's main cue.
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

  • warning description-no-when description does not say WHEN to use the skill (no "use when")
  • note edit-residue the text marks something as outdated (lines 59): check that old rules are not kept next to new ones — the full check reads the text for contradictions

Process rating: all ten parameters 41/100

  • 0Result and completion. Does not say what the result is
  • 0Inputs and preconditions. Does not say what the process needs to start
  • 0Failures and branches. Linear process with no failure handling
  • 0Progress reporting. Says nothing while it works
  • 20When it triggers. No condition that starts the skill
  • 30Running it twice. 4 mutating operations with no state check
  • 60Tools and files. Uses tools (python) that frontmatter does not declare
  • 85Steps. 24 steps, 1 vague phrases
  • 100Consistency. Name and required fields are in place
  • 100Execution cost. Instruction body is 753 tokens

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.
