What it does

Secure Development Policy is an agent skill from Hack23/cia. Hack23 secure development policy enforcement, SAST/DAST integration, dependency scanning, and code signing practices

Its SKILL.md is about 1.7k 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 Static analysis and SAST and App store release. The repository describes itself as: Citizen Intelligence Agency. Open-source intelligence platform analyzing Swedish political activities using AI and data visualization. Tracks politicians, government… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Static analysis and SAST
  • Tasks that involve App store release

Example prompts

  • “/secure-development-policy”

Requirements

  • Docker
  • A credential in API_KEY

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Static Application Security Testing (SAST)
  2. Dynamic Application Security Testing (DAST)
  3. Dependency Scanning
  4. Code Signing and Integrity
  5. Secure Coding Standards

What it can do on your machine

Read from SKILL.md and the folder at commit 6a9797b. 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:

    • staging.cia.hack23.com

    Also links to:

    • github.com
    • owasp.org
    • cisecurity.org
    • csrc.nist.gov

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Secure Development Policy loads about 1.7k tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 411 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
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

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.

Secure Development Policy Skill

Purpose

This skill enforces the Hack23 Secure Development Policy across the CIA platform. It provides actionable guidance for SAST/DAST integration, dependency scanning, code signing, and policy compliance verification in daily development workflows.

When to Use This Skill

Apply this skill when:

  • ✅ Reviewing PRs for policy compliance
  • ✅ Configuring CI/CD security scanning pipelines
  • ✅ Adding or updating dependencies
  • ✅ Setting up new development environments
  • ✅ Investigating security scan findings
  • ✅ Preparing code for release
  • ✅ Auditing existing code against policy requirements

Do NOT use for:

  • ❌ High-level SDLC planning (use secure-development-lifecycle)
  • ❌ Runtime security monitoring (use incident-response)
  • ❌ Architecture-level security design (use security-architecture-validation)

Policy Requirements

1. Static Application Security Testing (SAST)

Required Tools:

ToolPurposeCI IntegrationBlocking?
CodeQLSemantic code analysisGitHub ActionsYes — zero critical/high
SonarCloudCode quality + securityGitHub ActionsYes — quality gate
SpotBugsJava bug detectionMaven pluginAdvisory

CodeQL Configuration:

yaml
# .github/workflows/codeql.yml
- uses: github/codeql-action/analyze@v3
  with:
    languages: java
    queries: +security-extended

SonarCloud Quality Gate:

# Required passing conditions
- No new critical issues
- No new high security hotspots
- Coverage ≥ 80% on new code
- Duplication < 3% on new code

Developer Actions:

□ Run CodeQL locally before pushing: codeql database create --language=java
□ Check SonarCloud dashboard after PR creation
□ Address all critical/high findings before merge
□ Document false positives with justification
2. Dynamic Application Security Testing (DAST)

4. Code Signing and Integrity

Commit Signing:

bash
# All commits should be signed
git config --global commit.gpgsign true
git config --global user.signingkey <GPG-KEY-ID>

Artifact Integrity:

  • Maven builds produce checksums for all artifacts
  • Release artifacts are signed
  • Docker images use content trust
  • CloudFormation templates are versioned and checksummed
5. Secure Coding Standards

Mandatory Practices:

PracticeEnforcementTool
Input validationAll user inputsSpring Validation + custom
Output encodingAll rendered dataVaadin built-in + manual
Parameterized queriesAll database accessJPA/Hibernate
Error handlingNo info leakageCustom exception handlers
LoggingNo sensitive dataSLF4J + Logback
AuthenticationSpring SecurityFramework default
CSRF protectionAll state changesSpring Security

Banned Patterns:

java
// BANNED: String concatenation in queries
entityManager.createQuery("SELECT p FROM Person p WHERE p.id = " + id);

// BANNED: Logging sensitive data
log.info("User login: " + username + " password: " + password);

// BANNED: Disabling CSRF
http.csrf().disable(); // Only if explicitly justified and documented

// BANNED: Hardcoded credentials
private static final String API_KEY = "sk-1234567890";

Policy Compliance Verification

PR Review Checklist
□ CodeQL scan passes (zero critical/high alerts)
□ SonarCloud quality gate passes
□ OWASP Dependency Check passes (CVSS < 7)
□ No banned code patterns detected
□ Input validation present for all user inputs
□ Output encoding verified for rendered data
□ No secrets or credentials in code
□ Commit is signed (GPG or SSH)
□ Test coverage meets thresholds (80% line, 70% branch)
□ Security-relevant changes documented
Quarterly Audit Checklist
□ All dependencies updated to latest stable
□ No open critical/high Dependabot alerts
□ DAST scan completed and findings addressed
□ Security documentation current
□ ISMS controls verified
□ Threat model reviewed and updated
□ Access controls reviewed
