Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00000 | $0.00682 |
| Opus 5 | $0.00000 | $0.00341 |
| Sonnet 5 | $0.00000 | $0.00136 |
| Haiku 4.5 | $0.00000 | $0.00068 |
Grade A, and why
index 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.
How it starts
The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agents
Reference documentation for every application agent under
ts/packages/agents/**. Agents are the plugins the
dispatcher routes typed actions to. Each one
exports an instantiate(): AppAgent function and implements the AppAgent
interface from @typeagent/agent-sdk.
Use the left-hand navigation to browse agents. As with packages, each agent's
hand-written README is shown as its Overview page, and its
README.AUTOGEN.md companion (when present) appears as a secondary
Generated README page — see the doc-autogen guide.
Understand the patterns first
Before reading individual agents (or building one), read Agent patterns. Every agent follows one of nine patterns based on how it talks to external systems, whether it keeps state, and what output it produces:
| Pattern | When to use | Examples |
|---|---|---|
schema-grammar |
Bounded set of typed actions (default) | weather, photo, list |
external-api |
Authenticated REST / cloud API | calendar, email, player |
llm-streaming |
Agent calls an LLM, streams results | chat, greeting |
sub-agent-orchestrator |
API surface too large for one schema | desktop, code, browser |
websocket-bridge |
Automate a host app via a plugin | browser, code |
state-machine |
Multi-phase workflow with approval gates | onboarding, powershell |
native-platform |
OS / device APIs, no cloud | playerLocal, desktop |
view-ui |
Rich interactive web-view UI | turtle, montage, markdown |
command-handler |
Simple settings-style direct dispatch | settings, test |
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.

index is an agent published in the GitHub repository microsoft/TypeAgent (738 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 682 tokens. 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.
