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 | $0.01005 | $0.01005 |
| Opus 5 | $0.00502 | $0.00502 |
| Sonnet 5 | $0.00201 | $0.00201 |
| Haiku 4.5 | $0.00101 | $0.00101 |
Grade A, and why
adguardctrl 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 2d 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.

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Repository Guidance
Definition of Done
Before reporting any code change as complete, run:
./scripts/verify
It runs npm run typecheck, npm test, and npm run build. Report the actual
results, paste failures verbatim, and never claim success you did not observe.
Project Shape
- TypeScript MCP server for AdGuard Home and AdGuardHome Sync. It exposes 33 tools across read, safe-write, and destructive tiers.
mcp-server.tsis the stdio MCP entry point.index.tsis the OpenClaw plugin entry point. Both must register tools throughbuildAllTools()insrc/tools/index.ts.- Tool implementations live one per file under
src/tools/. When adding or removing a tool, update the explicit import/export list insrc/tools/index.ts; it is the canonical registration list.
Hard Prohibitions
- A pre-push hook exists (
hooks/pre-push, wired viacore.hooksPath). Never push with--no-verify. If the hook blocks, fix the flagged content or add the documented inline allow tag, then push normally. - Never weaken, skip, or delete failing tests, and never weaken or remove the tier gates (
assertConfirmedWrite,assertDestructive) to make something pass. Fix the code instead. - Never invent npm scripts, tool names, endpoints, or API facts. Verify against
package.json,src/tools/index.ts, and the code before citing them. - When blocked, report the exact blocker (command, full error output) and stop. Do not work around it silently.
Safety Rules: Tier Gates
- Adding or editing a Tier-2 write tool: it must call
assertConfirmedWrite(raw, NAME)before any network request. Tier-3 destructive tools must callassertDestructive(raw, NAME)before any network request. Reads need no gate. - Building a request body: never forward
instance,confirm,destructive, or future gate-only fields to AdGuard Home request bodies. Strip them first. - Touching credentials: keep credential handling in
src/security.tsand register any derived secret forms, especially Basic auth header values, before serving tools.
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.

adguardctrl AGENTS.md is an instructions file published in the GitHub repository lidless-labs/adguardctrl (2 stars, last pushed 17d ago), licensed MIT. It adds 1,005 tokens to every session, about $0.0050 per session on Opus 5. 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 2026-08-31.
