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 | $0.00757 | $0.00757 |
| Opus 5.5 | $0.00303 | $0.00303 |
| Sonnet 5.5 | $0.00151 | $0.00151 |
| Haiku 4.5 | $0.00076 | $0.00076 |
Grade A, and why
agent-insights 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Insights Backend
Rust backend API for scanning and aggregating AI agent usage data.
Features
- Scans local agent directories (Claude, Gemini, Codex)
- Parses JSON/JSONL session files
- Aggregates data by date for heatmap visualization
- RESTful API with CORS support

Implementation Details
Claude Scanner
- Location:
~/.claude/projects/ - Format: JSONL (newline-delimited JSON)
- Extracts: session_id, token usage (input/output/cached)
- Pattern: One event per line
Gemini Scanner
- Location:
~/.gemini/tmp/{hash}/chats/ - Format: JSON
- Extracts: session_id, token usage
- Pattern: Multiple chat files per session
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.

agent-insights AGENTS.md is an instructions file published in the GitHub repository milisp/agent-insights (3 stars, last pushed 13d ago), licensed MIT. It adds 757 tokens to every session, about $0.0030 per session on Opus 5.5. 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.
