What is agent-wiki AGENTS.md?

A project documentation standard and service for keeping one agent-readable AGENTS.md wiki per project. It includes rules, an indexer, a read-only web interface, and an API.

Use it to define AGENTS.md files, build searchable project and topic indexes, validate documentation, and browse project links, backlinks, and raw documents.

It gives coding agents a consistent place to learn a project's purpose, architecture, deployment details, and known problems. Indexing and validation make those documents easier to search and check.

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	$0.04177	$0.04177
Opus 5.5	$0.01671	$0.01671
Sonnet 5.5	$0.00835	$0.00835
Haiku 4.5	$0.00418	$0.00418

Security

Grade B, and why

agent-wiki AGENTS.md scanned grade B 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 1mo 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

**Production updates:** `git pull && (cd service && npm install && npm run build) && (cd ui && npm install && npm run build) && sudo systemctl restart agent-wiki`.

AGENTS.md — agent-wiki

What This Is

A documentation standard and supporting service for per-project agent-readable wikis. Each project in your workspace gets a single AGENTS.md describing intent, architecture, deployment, gotchas, and cross-project links. This repo defines the spec, hosts cross-cutting topics, and runs a small read-only browser/API.

Status

Spec + indexer + server + UI + sweeper. All pieces working:

Spec defined (spec/schema.md), template (spec/template.md), topics tier rules (spec/topics.md).
Indexer parses frontmatter + sections + links, validates, writes index/{projects,topics,backlinks,search,validation}.json. Also writes generated backlinks footers back into source AGENTS.md files (write_backlinks.ts).
Read-only HTTP API in service/src/server/ with Google OAuth (allowlist) + file-based sessions, mounted at PATH_PREFIX (default /wiki). JSON endpoints for projects, topics, search, validation, raw doc bodies.
React + Vite UI in ui/, served by the Express process from ui/dist/. Pages: Home, Project, Topic, Search, Validation, Login. Markdown rendered with react-markdown + remark-gfm; cross-doc links rewritten to in-app routes.
Sweeper service in service/src/sweeper/: gathers per-project git activity since last_updated, calls the Claude API (streaming, 32k max_tokens, string-aware brace-counter parser), applies section-level patches, updates frontmatter. CLI supports per-project runs, --all fan-out, and --dry-run. Sweeper auth supports both ANTHROPIC_API_KEY and the Claude Code CLI's own credentials.
Optional automation: on Linux, a daily user-mode systemd timer (agent-wiki-sweeper.timer) runs sweeper --all && indexer build; on macOS, an equivalent LaunchAgent (agent-wiki-sweeper.plist) does the same. A Claude Code Stop-hook (deploy/sweep-on-stop.sh) fires per-project sweeps async, debounced to 60 min/project, and is portable across both OSes.

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.
