Write and review application code that satisfies the Singapore Government ICT&SS Policy Reform Application Security (AS) controls and allied Cryptography/Key Management (CK) controls. Use whenever writing new code, reviewing a diff, or auditing an existing codebase for a Singapore government agency project — especially anything touching input handling, database queries, authentication, passwords, sessions, secrets, crypto, HTTP security headers, file uploads, or error handling.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Secure coding for SG Government: AS + CK controls

The ICT&SS Policy Reform (IM8's successor) Cybersecurity Control Catalog contains 15
Application Security (AS) controls and 4 Cryptography/Key Management (CK) controls that
land directly in application code. This skill maps them to coding decisions so an agent
writing or reviewing code produces compliant output the first time, with control IDs the
agency's security team can trace to its System Security Plan (SSP).

Use this skill in three modes:

1. **Writing new code**: apply the scenario sections below as you write.
2. **Reviewing a diff**: run the review checklist against every changed file; flag
   violations with the control ID.
3. **Auditing a codebase**: sweep for each checklist row; report findings per control ID
   with file:line references.

## Source and currency

Control text in this skill and in [references/as-controls.md](references/as-controls.md)
is embedded from **info.standards.tech.gov.sg as of 2026-07-16**. The standards iterate
actively. For compliance-critical decisions (SSP evidence, audit responses, deviations),
verify against the live pages:

How to install

The exact contents, by fingerprint

mdr add kyleoliveiro/sg-gov-skills/sg-gov-secure-coding-as@sha256:32ab4ae54313a091

The line at the top of this page pins the label git:20261027.6f21efa, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
