Apply the organization's secure development policy. Use when writing a spec or plan, handling authentication, secrets, cryptography, file uploads, external input, third-party dependencies, or any data classified as confidential or personal.

The file

We split this skill into the rules it gives an agent

3 rules. About 0 are common, 0 are distinctive, and 3 are very specific to this project.

  • ≈0

    Common · estimate

    Many files like this have a rule of this kind.

  • ≈0

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 3

    Very specific

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

  • Common
  • Distinctive
  • Very specific
  1. Very specific:

    Secrets: never in code, config files or logs.

    line 13
  2. Very specific:

    Dependencies: only from <approved registries>.

    line 14
  3. Very specific:

    Cryptography: use <approved library>; no custom crypto.

    line 16

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “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.

Secure development policy

Owner: <CISO delegate> · Source of truth: <link to the security policy> · Policy version: <x.y>

<!-- TEMPLATE: replace each rule with your organization's policy text, keeping one rule per line. -->

Rules

  1. Secrets: never in code, config files or logs. Read them from <secret manager>.
  2. Dependencies: only from <approved registries>; no new dependency without a licence and vulnerability check (<tool>); never bump versions the platform team owns.
  3. Cryptography: use <approved library>; no custom crypto; minimum <TLS 1.2 / AES-256 / ...>.
  4. Data classification: <public | internal | confidential | restricted>. Restricted data stays in <approved stores> and is encrypted at rest.
  5. External input: validate at the boundary; parameterized queries only; no shell interpolation of user input.
  6. Logging: log security events (auth failures, permission denials) without personal data.
  7. Threat model: changes that add a new trust boundary need a short threat model in spec.md.

When writing a spec or plan

List each rule the change touches and how it is satisfied. Where two rules or two policies conflict, do not choose: record it under Areas of concern and name this policy's owner.

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.
