Authgear is an open-source identity and authentication service that provides login, account management, multi-factor authentication, passkeys, and single sign-on for applications. SaaS and mobile-app developers can run it themselves or use Authgear Cloud to manage consumer and enterprise user access. The catalogue entries relate to operating and configuring Authgear's authentication workflows.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.00337 |
| Opus 5.5 | $0.00006 | $0.00135 |
| Sonnet 5.5 | $0.00003 | $0.00067 |
| Haiku 4.5 | $0.00001 | $0.00034 |
Grade A, and why
update-go-version 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 yesterday.
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.
What it actually says
Use this skill when the Go version changes.
Files to update

Workflow
- Update the version in every file above.
- Use
nix store prefetch-fileto refresh the hash inflake.nix. - Run
make go-mod-tidy. - Run
make once/Dockerfile. - Grep the repo for the old version to catch any file missing from the list above, and update or consciously skip each hit:
grep -rnF '<old version>' --exclude-dir=node_modules --exclude-dir=.git --exclude=package-lock.json --exclude=go.sum .Also grep for other1.26.xpatch versions (docs,.codebox.conf, skills) that may have drifted earlier. - Verify the repo still builds if the version bump changed tool behavior.
Notes
- Keep the version updates consistent across all Go modules.
- Do not leave one module on the old version; that creates hard-to-debug drift.
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.

update-go-version is a skill published in the GitHub repository authgear/authgear-server (2,133 stars, last pushed yesterday), licensed Apache-2.0. It adds 14 tokens to every session and 337 once invoked, about $0.0001 per session on Opus 5.5. 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.
