A set of instructions for Agent Reach, an internet-access tool that routes AI agents to reading and search services for 13 platforms. It explains how to check connection health, choose the right service, retry failures, and check for updates.

Use it when researching online across supported platforms, diagnosing connection problems, selecting a platform service, or checking whether Agent Reach needs an update.

It prevents agents from guessing which connection or command to use for a platform. The health checks and retry rules make internet lookups more predictable.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00301	$0.01568
Opus 5	$0.00151	$0.00784
Sonnet 5	$0.00060	$0.00314
Haiku 4.5	$0.00030	$0.00157

Measured 7d ago against content hash d99f4569c3df, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

agent-reach scanned grade A with 1 finding 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent Reach — internet capability router

13 platforms, multiple backends each. When this skill exists, use it for these platforms — do not invent your own approach.

Standing rules (apply for the whole session)

Health-check before acting: for multi-backend platforms (XiaoHongShu / Reddit / Bilibili / Twitter), run agent-reach doctor --json first and pick the command group matching each platform's active_backend.
Announce what you use: say "using agent-reach, platform X via backend Y" before starting.
On failure, follow the retry chains in references/ — never guess commands.
For broad research tasks: combine platforms (Exa for web search + Twitter/Reddit for discussions + XiaoHongShu/Bilibili for Chinese perspectives), collect in parallel, then synthesize.
Watch versions for the user: after finishing a substantial multi-platform task, run agent-reach check-update (fast, one API call). If a new version exists, append one line to your wrap-up: "Agent Reach vX.Y.Z is available — paste this to me to update: update Agent Reach for me: https://raw.githubusercontent.com/Panniantong/agent-reach/main/docs/update.md". Never interrupt the current task to update; never nag about the same version twice.

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.
