ssp-navigator

ssp-navigator is a skill for Claude Code, Codex from kyleoliveiro/sg-gov-skills. It costs 144 tokens per session (3,541 once invoked), scanned A, original, MIT.

A guide that selects the Singapore Government System Security Plan (SSP) or plans required for a system. An SSP is a documented set of security controls; the guide also considers profiles for generative AI and digital services.

In plain words
What is it for?
Use it when building or reviewing a Singapore government system to identify its control baseline, adjust the controls, approve remaining risks, and prepare the required lifecycle and repository steps.
Why use it?
Choosing the right SSP early shows which security requirements apply and can reveal architecture constraints such as data location, logging, and domain registration.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ssp-navigator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 283 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SSP Navigator

Map a system's characteristics to the correct System Security Plan(s) from the Singapore Government's ICT&SS Policy Reform (the successor to IM8), then report the control baseline and the lifecycle steps the team must complete.

An SSP is the implementable control set for one system. Agencies pick one of 8 published SSP templates by system characteristics, tailor it, get residual risk approved, and submit it to a whole-of-government repository. Getting the SSP selection right up front matters because it determines which controls are mandatory (Level 0), which are default hygiene (Level 1), and which are optional best practice (Level 2) — and because several Level 0 controls (data residency, central logging, domain registration) constrain architecture decisions that are expensive to reverse.

Source and currency

Content embedded from info.standards.tech.gov.sg as of 2026-07-16 (source pages last updated March–May 2026). The standards are actively iterating: when making compliance-critical decisions, verify against the live pages before relying on embedded figures.

Source URLs:

Machine-readable OSCAL: https://github.com/GovtechSG/tech-standards — MIT-licensed OSCAL 1.1.2 JSON, but it lags the website (catalog version 2025.05.13; no Gen-AI, DSS, high-risk, or sandbox profiles). The site is authoritative.

Step 1 — Gather the classification inputs

Ask for (or determine from project context) all six inputs before selecting anything. Partial answers produce wrong baselines — e.g. missing the GenAI usage means missing four mandatory controls.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ssp-navigator is a skill published in the GitHub repository kyleoliveiro/sg-gov-skills (16 stars, last pushed 1mo ago), licensed MIT. It adds 144 tokens to every session and 3,541 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
