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 | $0.06187 | $0.06187 |
| Opus 5 | $0.03093 | $0.03093 |
| Sonnet 5 | $0.01237 | $0.01237 |
| Haiku 4.5 | $0.00619 | $0.00619 |
Grade A, and why
refd 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 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 — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI coding agents working in this repository.
CLAUDE.md is the Claude Code twin of this file — apply any change to both.
What this is
refd (refd.ai) — open-source AI search monitoring. Each workspace tracks one brand's visibility, mentions, citations, and rank across AI answer surfaces: ChatGPT, Perplexity, Gemini, Google AI Mode (BrightData dataset scrapers), and Google AI Overviews (BrightData SERP API). BrightData is the only data provider. Available hosted (refd.ai) or self-hosted; born tracking mrmr, since generalized. Public copy never pairs "refd" with "aeo".
Reference docs: docs/DESIGN.md (design system — all UI work follows it), docs/METRICS.md (scoring and aggregation contract), and docs/mcp.md (remote MCP and OAuth usage).
Monorepo layout
Bun workspaces (apps/*, packages/*) — three independently deployed Cloudflare Workers plus a shared package (docs/plan-three-worker.md).
apps/api(@refd/api,api.refd.ai) — the Worker: Hono API, OAuth, MCP, cron trigger, queue consumer, every binding (D1, R2, KV, Queues, AI, Browser, rate limits), and secrets (apps/api/.dev.varslocally). The only Worker that declares bindings, cron, or queue consumers — CI enforces this viascripts/check-worker-topology.sh.apps/dashboard(@refd/dashboard,dash.refd.ai) — the React + Vite SPA as an assets-only Worker (@/*→src/*).noindex, with its ownpublic/robots.txt+public/_headers(CSP allowsapi.refd.ai) and no landing route. It calls the API cross-origin, so its client builds absolute URLs fromVITE_API_ORIGINand sendscredentials: 'include'.apps/web(@refd/web,refd.ai) — the public site: a static Astro build fronted by a tiny Worker (src/worker.ts) that does homepage Markdown negotiation over the assets. Owns the indexable SEO assets (apps/web/public/),@astrojs/sitemap, JSON-LD, and the static 404. Pure.astro(Biome-excluded;astro checkcan't run on the repo's TS 7, soastro buildvalidates the templates); CTAs link todash.refd.ai.packages/core(@refd/core) — runtime-neutral code shared across Workers (config,surfaces,mentions,workspaces,site-metadata,blocks,metric-copy,glossary,public-pages), imported via subpaths like@refd/core/config. No build step; consumers bundle the TS source.
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.
