sage-eval-gauge

sage-eval-gauge is a skill for Claude Code, Codex from MythicAgents/sage. It costs 108 tokens per session (8,666 once invoked), scanned A, original, GPL-3.0.

A repo-local toolkit for testing how well Sage, an AI system, performs on defined tasks. It uses checked ground-truth answers and includes a hill-climbing test phase.

In plain words
What is it for?
Use it to run Sage capability tests, validate an evaluation against reality, measure normal score variation, and compare bare-model and harness results.
Why use it?
It helps avoid misleading scores based only on matching words in an answer. It checks whether the evaluation actually reflects real capability and compares the system with and without its supporting harness.

Token cost

What 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.

Security

Grade A, and why

sage-eval-gauge 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 6d ago.

The scan reads SKILL.md. This mod also ships 39 executable files (scripts/accounting.py, scripts/bh_cypher.py, scripts/capture_composite_bridge.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

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.
