    agent-sort

    Build an evidence-backed ECC install plan for a specific repo by sorting skills, commands, rules, hooks, and extras into DAILY vs LIBRARY buckets using parallel repo-aware review passes. Use when ECC should be trimmed to what a project actually needs instead of loading the full bundle.

The file

We split this skill into the rules it gives an agent

2 rules. 0 are common, 2 are distinctive, and 0 are very specific to this project.

  • 0

    Common

    Most of the 167 edited versions we read keep these.

  • 2

    Distinctive

    This author's own choices. Worth a look.

  • 0

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  • Common
  • Distinctive
  • Very specific
  1. Distinctive:

    Check whether validation, authorization, escaping, isolation, and failure behavior occur at the correct boundary.

    line 27
  2. Distinctive:

    Do not manufacture a generic security checklist for changes that do not affect a meaningful security boundary.

    line 31

“Common” is measured: kept by at least 6 in 10 of the 167 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Keep what fits and drop the rest. Your version, ready for your agents.

Security review

Invoke this skill when the change materially affects a security boundary.

Review triggers

Examples include:

  • authentication or session behavior;
  • authorization or permission checks;
  • secret/credential handling;
  • cryptographic operations or key material;
  • parsing or executing untrusted input;
  • filesystem, process, shell, network, or device privileges;
  • sensitive-data storage or transmission;
  • dependency/supply-chain changes with meaningful privilege.

Procedure

  1. Identify assets, trust boundaries, attacker-controlled inputs, and privilege transitions actually touched by the change.
  2. Trace the changed data/control flow.
  3. Check whether validation, authorization, escaping, isolation, and failure behavior occur at the correct boundary.
  4. Distinguish demonstrated vulnerabilities from optional hardening.
  5. For each substantive finding state attacker preconditions, exploit/failure path, impact, evidence, and mitigation direction.

Do not manufacture a generic security checklist for changes that do not affect a meaningful security boundary.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
