peerd CLAUDE.md

peerd CLAUDE.md is an instructions file for coding agents from NotASithLord/peerd. It costs 8,917 tokens per session, scanned A, a copy of peerd AGENTS.md, Apache-2.0.

A project instruction file for peerd, a browser extension that runs an AI agent in the user's browser and can control browser pages and sandboxed shell commands. It describes the project's five modules, technologies, and required reading order.

In plain words
What is it for?
Use it when working on peerd's model adapters, browser extension code, sandbox, user interface, or related project structure.
Why use it?
It gives coding agents the context and conventions needed to modify an experimental browser extension safely and consistently.

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

peerd CLAUDE.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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 560 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md — peerd

Persistent project context for Claude Code. Read this first on every session. Equivalent to OpenCode's AGENTS.md pattern.


What peerd is

A browser-native AI agent harness, shipped as a Chrome/Firefox extension. The agent runs entirely in the user's browser. It talks to a model API directly (BYOK — bring your own key), drives the browser's tabs and DOM, and can run shell commands in a sandboxed Linux VM compiled to WebAssembly. No backend, no telemetry, no account.

peerd is 0.x — experimental beta (breaking changes likely; no "V1" commitment — versions stay 0.x until the surface stabilizes). The initial feature buildout is complete and integrated; current work is store-readiness polish and field hardening. Stack: Manifest V3, Chrome and Firefox (via webextension-polyfill), vanilla JS, no build step.


The codebase is five modules

Each maps to one letter and color in the brand wordmark:

Letter Color Module Role
p cyan peerd-provider/ Model adapters (Anthropic, OpenRouter, OpenAI, Z.ai GLM, and keyless Ollama shipped; local WebGPU gated on the resident engine — registry.js is the live list)
e red peerd-egress/ Security: vault, allowlist (safeFetch), denylist, audit
e amber peerd-engine/ Execution instances — Sandboxes. Three kinds run in their own visible tab: WebVMs (CheerpX Linux), Notebooks (sealed JS worker + OPFS), Apps (opaque-origin iframe). A fourth, the headless worker (script), runs the Notebook's sealed worker offscreen with no tab — the agent's own quick compute. The sandbox is the isolate; a tab is one way to host it (taxonomy in the peerd-engine/ code).
r green peerd-runtime/ Agent loop, tools + per-environment actors (message_actor), sessions, profiles, skills, memory, permissions (Plan/Act), review, goal mode (autonomous loop), composer, cost, transfer, voice, clock, web tool policy
d magenta peerd-distributed/ The dweb. An always-on P2P base network (offscreen mesh + DHT + gossip), did:key identity, signed content addressing, the dwapp bridge, and a peer-to-peer app store that users AND the agent build, share, and run dwapps on. Chrome preview only until Firefox has a mesh host.

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.
