Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00200 | $0.03247 |
| Opus 5 | $0.00100 | $0.01623 |
| Sonnet 5 | $0.00040 | $0.00649 |
| Haiku 4.5 | $0.00020 | $0.00325 |
Grade A, and why
singpass 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 10d 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 — 209 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Singpass: citizen login and Myinfo (v5) on FAPI 2.0
Singpass is Singapore's national digital identity — an OpenID Connect provider, authorization-code flow only, relying parties must be confidential clients. Two products ride on one API and one onboarding portal:
- Singpass Login — authentication only. The flow ends at the ID token.
- Singpass Myinfo (v5) — Login plus consented retrieval of government-verified
person data from the
/userinfoendpoint. Every Singpass user automatically has a Myinfo profile.
The current API is fully OIDC + FAPI 2.0 compliant (new apps are FAPI 2.0 by default since Feb 2026; all Singpass APIs must be FAPI 2.0-compliant by 31 Dec 2026). Use a certified OIDC relying-party library (openid.net certified list) rather than hand-rolling — Singpass says so explicitly, and the library gets PAR, PKCE, DPoP, and claim validation right for free. If you are maintaining a Myinfo v3/v4 integration or a pre-FAPI Login flow, read singpass-legacy — different endpoints, different crypto, hard deadlines.
The single most important identity fact: the ID token sub is a UUID, never the
NRIC. NRIC/FIN arrives only if you request the justification-gated user.identity
scope (sub_attributes.identity_number) or the uinfin Myinfo scope. Key your user
records on the UUID; the PDPC NRIC advisory guidelines apply the moment you store
NRIC instead.

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

singpass is a skill published in the GitHub repository kyleoliveiro/sg-gov-skills (16 stars, last pushed 1mo ago), licensed MIT. It adds 200 tokens to every session and 3,247 once invoked, about $0.0010 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.
