What it does
Review Plan is an agent skill from shader-slang/slangpy. Review a plan using sub agents and provide feedback on how to improve it.
Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows, covering Subagents. The repository describes itself as: Making it easier to work with slang in python.
When your agent uses it
- Tasks that involve Subagents
Example prompts
- “/review-plan”
What it can do on your machine
Read from SKILL.md and the folder at commit ce68ef8. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Review Plan loads about 367 tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 187 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 187 words (~367 tokens).
“Use this skill to review an implementation plan, ExecPlan, design note, or proposed task breakdown before coding. Prefer this for plans that touch multiple SlangPy layers, GPU behavior, the functional API, build configuration, or user-visible public APIs.”
