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.
npx agentmods add instructions/freyr/traefik/claude-mdgit clone --depth 1 https://github.com/freyr/traefikWhat 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 | $0.00559 | $0.00559 |
| Opus 5 | $0.00280 | $0.00280 |
| Sonnet 5 | $0.00112 | $0.00112 |
| Haiku 4.5 | $0.00056 | $0.00056 |
Grade B, and why
traefik CLAUDE.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 3d 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.
- **TFK001**: First-time setup requires `sudo make create` — installs loopback alias LaunchDaemon on macOS. How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Traefik
Local development reverse proxy routing HTTPS for *.example.dev via loopback alias 172.16.123.1.
Critical Rules
- TFK001: First-time setup requires
sudo make create— installs loopback alias LaunchDaemon on macOS. - TFK002: Services must opt in with
traefik.enable=truelabel —exposedByDefaultis false. - TFK003: SSL key must have
644permissions — Docker container needs read access. - TFK004: Use
fullchain.pem(notcert.pem) — includes intermediate certificates.
Quick Start
# One-time setup (requires sudo on macOS)
sudo make create # Loopback alias + network + start Traefik
# Daily operations
make start # Start Traefik
make stop # Stop Traefik
make destroy # Remove everything
make # Show help
Certificate Management
make setup-certs # Copy Let's Encrypt certs to Traefik
make install-renew-hook # Post-renewal hook
make setup-auto-renewal # Automatic renewal (macOS LaunchDaemon)
make test-renewal # Dry-run renewal test
Service Discovery
Add these Docker labels to expose a service:
labels:
traefik.enable: true
traefik.http.routers.<service>.tls: true
traefik.http.routers.<service>.entrypoints: websecure
traefik.http.routers.<service>.rule: "Host(`subdomain.example.dev`)"
Architecture
- Traffic flow: Client → 172.16.123.1:443 → Traefik → containers on
localDocker network - Static config:
traefik.toml(entrypoints, providers) - TLS config:
configs/certs.toml+ssl/directory - Auto HTTP→HTTPS redirect; dashboard at
https://traefik.example.dev - Platform setup: macOS (LaunchDaemon), Linux (systemd), Windows (manual)

Boundaries
NEVER:
- Commit SSL private keys to git
- Modify loopback alias config without testing connectivity afterward
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.

traefik CLAUDE.md is an instructions file published in the GitHub repository freyr/traefik (2 stars, last pushed 6mo ago), licensed MIT. It adds 559 tokens to every session, about $0.0028 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
