What it does

Psalm Security Analysis is an agent skill from cachethq/core. Runs and interprets Psalm security (taint) analysis on a Laravel project. Use when the user asks to find security vulnerabilities, run a security scan, check for SQL injection or XSS, audit code for taint issues, or fix Psalm taint errors. Also use when investigating data flow from user input to sensitive operations, even if the user doesn't explicitly mention Psalm or taint analysis. Requires psalm-plugin-laravel installed.

Its SKILL.md is about 4.7k 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 Security, covering Backend development, Web application vulnerabilities and Static analysis and SAST. It works with Laravel. The repository describes itself as: 🚦 The core for Cachet, an open source, self-hosted status page system.

When your agent uses it

  • The user asks to find security vulnerabilities
  • Run a security scan
  • Check for SQL injection
  • Audit code for taint issues

Example prompts

  • “/psalm-security-analysis”

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Is there a real path from user input to the sink? (or is the tainted value from a model/service that doesn't actually accept user data?)
  2. Is there any sanitization/validation between source and sink? (allowlist check, in_array, cast to int, e(), parameterized query?)
  3. What's the access level? (public endpoint vs admin-only, affects real-world exploitability)

What it can do on your machine

Read from SKILL.md and the folder at commit 57b44a8. 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:

    • jq
    • rg

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

  • Network

    Links to these hosts (documentation or services it may open):

    • 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.

Context cost

Psalm Security Analysis loads about 4.7k tokens when it runs. Until then it costs about 113 tokens; SKILL.md has 1,580 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~113
When it runs · the whole SKILL.md, loaded when a task matches
~4.7k

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

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 1,580 words (~4,697 tokens).
