Posture

What it does

When your agent uses it

• Development work in your project

Example prompts

• “/posture”

Requirements

• Compatibility (from SKILL.md): Needs network access to api.github.com and api.securityscorecards.dev. Works best on GitHub-hosted repositories; degrades to file-only checks elsewhere.

What it can do on your machine

Read from SKILL.md and the folder at commit f3407bf. 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

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Hosts in commands or code, which the agent is likely to contact:

  • api.github.com
  • api.securityscorecards.dev
  • github.com

  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.

• Compatibility

  Needs network access to api.github.com and api.securityscorecards.dev. Works best on GitHub-hosted repositories; degrades to file-only checks elsewhere.

  From compatibility in the SKILL.md frontmatter.

Context cost

Posture loads about 1.7k tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 678 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~102

When it runs · the whole SKILL.md, loaded when a task matches

~1.7k

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

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.

name

posture

description

Assess a repository's security posture and its readiness to receive a vulnerability report. Checks for a security policy, private vulnerability reporting, security.txt, prior advisories, scanning workflows, and other hygiene signals, then rates the project ready / partial / unprepared. Use before disclosure to decide how much hand-holding the maintainer will need, or as a standalone health check.

compatibility

Needs network access to api.github.com and api.securityscorecards.dev. Works best on GitHub-hosted repositories; degrades to file-only checks elsewhere.
