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.

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 | $0.00036 | $0.00677 |
| Opus 5.5 | $0.00014 | $0.00271 |
| Sonnet 5.5 | $0.00007 | $0.00135 |
| Haiku 4.5 | $0.00004 | $0.00068 |
Grade A, and why
update-email-templates 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 2mo 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.

Update Email Templates
Follow this workflow whenever updating email templates.
Scope Rules
- Only edit source template files:
resources/authgear/templates/en/messages/*.txt.gotemplateresources/authgear/templates/en/messages/*.mjml.gotemplate
- Do not edit generated template files directly:
resources/authgear/templates/en/messages/*.txtresources/authgear/templates/en/messages/*.mjml
- In
*.txt.gotemplateand*.mjml.gotemplate, use translations from:resources/authgear/templates/en/messages/translation.json
- Always edit English templates only at source stage.
- Do not manually update non-
enlocales in source-edit commits.
- Do not manually update non-
- Email subject translations are defined in:
resources/authgear/templates/en/translation.json
Workflow
- Edit source templates first:
resources/authgear/templates/en/messages/*.txt.gotemplateresources/authgear/templates/en/messages/*.mjml.gotemplateresources/authgear/templates/en/messages/translation.json(body/content translations)resources/authgear/templates/en/translation.json(subject translations)
- Generate
.mjmlfrom.mjml.gotemplate:go run ./scripts/generatemjml/main.go -i resources/authgear/templates
- Commit source edits and generated
.mjmlin one commit. - Before regenerating non-English translations, delete the changed keys from all non-
enlocale files so the generator knows to recreate them:- For
en/messages/translation.jsonchanges, delete the top-level key (e.g.UsageAlert, notUsageAlert.Alert.Title) from all non-enmessages/translation.jsonfiles:make templates-translation-json-del-key KEY=<TopLevelKey>
- For
en/translation.jsonsubject changes, delete the changed key from all non-entranslation.jsonfiles:make translation-json-del-key KEY=<key>
- Run once per changed top-level key.
- For
- In a separate commit, generate non-English translations:
make -C scripts/python generate-translations- Requires being logged in to Claude:
claude login - If not logged in, stop and ask the user to run
claude loginfirst.
- Finally, generate HTML emails:
make html-email
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.
