go-authcrunch: Skill for Codex

.codex/skills/documents-app-integration/SKILL.md

documents-app-integration is a skill for Codex from greenpau/go-authcrunch. It costs 44 tokens per session (3,755 once invoked), scanned A, original, Apache-2.0.

A frontend skill for connecting a separate React application to encrypted document storage. React is a JavaScript library for building user interfaces; the skill covers browser encryption, transfers, sharing, recovery, and session handling.

In plain words
What is it for?
It is for implementing and testing document upload, download, sharing, revocation, account switching, and recovery flows in a React app.
Why use it?
It helps keep the web interface aligned with the server's encryption protocol without assuming that the backend or production assets already exist.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: mentions AGENTS.md.

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 →

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

documents-app-integration 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 9d 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.

Documents React Integration

This skill is intended for the external React application's agent to read from its AuthCrunch library checkout. Keep implementation in the task's authorized repository; reading this skill does not authorize edits to sibling checkouts. For an app-local AGENTS.md, add a route pointing to this skill at the actual library checkout location. Do not copy a machine-specific path into the app's source. The File Vault bundle now ships under pkg/authn/ui/documents and is served at <portal>/documents/ when Documents is enabled; its React source remains in the separately maintained UI repository.

Read the crypto/wire contract and use the portable crypto.mjs module. Vendor a reviewed version into the frontend's source or bundle it via an explicit build dependency. It is plain ESM using native Web Crypto with no third-party runtime dependencies. It is not currently served by a production asset route. Preserve the protocol and test against the interoperability vector. Use the shared Mermaid sequences and design rationale to follow enrollment/unlock, encrypted upload/download, sharing, revocation and reset. They distinguish local crypto and required React UX from implemented server behavior, and explain retries, key context and account-switch protection. Keep these sequences and the protocol aligned when changing a client workflow.

The OpenAPI source describes the API. Its rendered /#tag/documents catalogue documents every operation's fields, request/response messages, state transitions and retry behavior. Every operation has its own method/resource path, expected response schema, parameter/body examples and native Test Request console. No plaintext-upload endpoint, username-directory endpoint or public share link exists. The manager application and profile application are separate products.

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.
