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

TyporAi AGENTS.md 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.

What it actually says

TyporAi contributor guide

TyporAi is a Typora sidebar plugin with four providers: Claude, Codex, OpenCode, and API. The shared chat feature owns presentation and provider-neutral contracts; each provider owns runtime protocol, settings reconciliation, history, and provider-specific workspace services.

Provider boundaries

  • Claude, Codex, and OpenCode are CLI providers. Their native capabilities must be declared in ProviderCapabilities and gated in the UI.
  • API is text-only. It may receive text from the active document and selection, but it must not expose or execute tools, MCP, commands, skills, subagents, plan mode, or filesystem operations.
  • Use provider-capability-matrix.md as the contract before changing provider behavior.

Terminology and storage

Use workspace and document in new user-facing and core code. Compatibility aliases may remain only while callers migrate. New TyporAi data writes to .typorai; .claude remains valid for Claude CLI-native configuration and read-only migration.

Settings and testing

Provider settings must provide clear save/error/restart semantics and preserve the mutual exclusion of CLI providers. Tests mirror src/ below tests/. Before submitting changes run:

npm run typecheck
npm run lint
npm run test
npm run build

The detailed inventories and allowlist live in docs/.

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.
