go-authcrunch: Skill for Codex

.codex/skills/sqlite-identity-store/SKILL.md

sqlite-identity-store is a skill for Codex from greenpau/go-authcrunch. It costs 49 tokens per session (1,562 once invoked), scanned A, original, Apache-2.0.

A pure-Go SQLite store for password-based user accounts. It handles account records, enrollment, password hashes, and identity evidence, but does not implement multi-factor authentication or profile features.

In plain words
What is it for?
Use it to provision accounts, connect an identity store to an authentication portal, support login checks, and run identity-related end-to-end tests.
Why use it?
It provides a local persistent place for login identities while keeping account creation and username and email normalization consistent. The database file is plaintext apart from bcrypt password hashes and must be kept private.

Skill for Codex

Written for Codex: agents/openai.yaml present.

This is greenpau/go-authcrunch's own configuration. It tells Codex how to work on go-authcrunch itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything go-authcrunch configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is make test TEST_DIR='./plugins/identity-stores/sqlite/... ./pkg/ids ./internal/tag'.

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

sqlite-identity-store 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 12d 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.

The opening of the file, as written. The whole thing — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SQLite Identity Store

plugins/identity-stores/sqlite implements ids.IdentityStore and the optional WithRefreshIdentity transaction capability. It reports kind sqlite, never local. Inject an open store into authn.PortalParameters.IdentityStores and select its name in PortalConfig.IdentityStores. Root hosts describe it through ids.NewExternalIdentityStoreConfig(name, "sqlite", realm, normalizedConfig), append that descriptor to Config.ExternalIdentityStores, and provide the open handle in ServerOptions.IdentityStores[name] to NewServerWithOptions. This preserves ordinary root assembly; built-in factories remain local/LDAP-only. The host owns the handle on success and on constructor failure, and closes it only after every sharing portal/root drains.

Descriptors contain name, actual kind, realm and a SHA-256 configuration digest; they contain no backend path, credentials or runtime handle. Normalize backend configuration through its parser/Validate before deriving the descriptor. Native JSON retains the descriptor but requires fresh runtime bindings after decoding. Root validation includes external names in default portal selection, disabled selection filtering and name/realm collision checks. Missing/extra bindings, misidentified or unconfigured handles, duplicate names and built-in kind impersonation fail before root resources are acquired.

The descriptor digest participates in persistent root compatibility. Root construction never attaches persistent state to an injected store or overrides its fresh proof epoch. Reopening SQLite invalidates restored refresh evidence; previously issued JWTs keep their configured lifetime. Changed backend identity or normalized configuration retires persisted authority through the root binding. Legacy local registry wiring, provider attachments and downstream OIDC local identity adapters do not accept this backend; profile credentials still require their independent capability. A password login integration does not grant those surfaces.

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.
