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 | $0.02340 | $0.02340 |
| Opus 5 | $0.01170 | $0.01170 |
| Sonnet 5 | $0.00468 | $0.00468 |
| Haiku 4.5 | $0.00234 | $0.00234 |
Grade A, and why
log-file-metric-exporter 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 10d 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.

Project Overview
The log-file-metric-exporter is a Prometheus exporter that monitors Kubernetes pod log files and exports the log_logged_bytes_total counter metric. This allows comparison of bytes actually logged versus what log collectors (e.g., Fluentd, Vector) are able to collect during runtime.
Core Principles
- Security First: Default to HTTPS with TLS; authentication should be the norm, not optional
- Kubernetes Native: Assume pod log structure at
/var/log/pods/<namespace>_<podname>_<uuid>/<container>/ - Simplicity: Prefer sequential metric updates and straightforward logic over extreme performance
- Testability: All components should have unit tests; benchmarks for performance-critical paths
Architecture Summary
See ARCHITECTURE.md for detailed design decisions, tradeoffs, and implementation details.
Core Components
-
Main Entry Point (
cmd/main.go)- Parses command-line flags (directory, port, TLS, auth token)
- Sets up HTTPS with TLS certificates and configurable cipher suites
- Mounts Prometheus metrics endpoint with optional bearer token auth
- Spawns LogWatcher in a background goroutine
-
Log Watcher (
pkg/logwatch/watcher.go)- Watches directory (default:
/var/log/pods) for file size changes - Parses Kubernetes log paths with regex to extract labels: namespace, pod name, pod UUID, container name
- Maintains last-known file sizes; detects growth, truncation, and deletion
- Updates
log_logged_bytes_totalcounter on size changes - Runs 5 concurrent goroutines to process events
- Watches directory (default:
-
Symlink Notifier (
pkg/symnotify/symnotify.go)- Wraps
fsnotify.Watcherto handle Kubernetes symlinked log files - Auto-adds watches for symlink targets and directories
- Recursively watches subdirectories; re-targets on symlink changes
- Critical for correctness (without this, many events would be missed)
- Wraps
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.

log-file-metric-exporter AGENTS.md is an instructions file published in the GitHub repository ViaQ/log-file-metric-exporter (2 stars, last pushed 13d ago), licensed Apache-2.0. It adds 2,340 tokens to every session, about $0.0117 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.
