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 | $0.00661 | $0.00661 |
| Opus 5.5 | $0.00264 | $0.00264 |
| Sonnet 5.5 | $0.00132 | $0.00132 |
| Haiku 4.5 | $0.00066 | $0.00066 |
Grade A, and why
sage 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 — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SAGE MANAGED BLOCK START
SAGE Integration - MANDATORY
When a user asks for any coding, repo, file, debugging, documentation, or project task, start through SAGE automatically. The user should not need to type sage.
First actions for normal repo work:
- Use native file/search/edit tools normally.
- Route every terminal command through the PyPI SAGE wrapper:
sage run -- <command>. - For multi-line file writes/appends, use native Write/Edit tools. Do not use shell heredocs through
sage run; heredocs are shell-specific and can fail through wrappers/monitors.
Route every shell command through SAGE. Do not run bare terminal commands.
Allowed wrapper:
sage run -- <command>
Rules:
- Python:
sage run -- python script.py - Packages:
sage run -- npm install - Tests:
sage run -- pytest - If the wrapper fails before the target command starts, stop and report the wrapper failure.
Why:
- Tracks local command history for the user
- Compresses noisy output before it reaches AI context
- Captures safe proof metrics for token savings and ML prediction
- Keeps raw commands and output local unless the user enables higher telemetry
Examples:
- Wrong:
python test.py - Correct:
sage run -- python test.py - Wrong:
git status - Correct:
sage run -- git status
Example user request:
- User: "Please help me with my general book in this folder"
- Correct agent start: inspect/read/edit files with available native tools, then use
sage run -- <command>only when a terminal command is needed. - Wrong agent start: bare
python,git,npm,ls, or other terminal commands without SAGE.
Any spawned subagent must be given the same SAGE shell-wrapper requirement in its prompt.
SAGE MANAGED BLOCK END
SAGE Repository Instructions
Mandatory Shell Wrapper
SAGE is installed in this repository. Route every shell command through the PyPI SAGE wrapper:
sage run -- <command>
Examples:
sage run -- git status
sage run -- python -m pytest
sage run -- npm install
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.

sage AGENTS.md is an instructions file published in the GitHub repository PsYcGoD/sage (11 stars, last pushed 16d ago), licensed MIT. It adds 661 tokens to every session, about $0.0026 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.
