eval

eval is a skill for Claude Code from jame581/LogseqBrain. It costs 50 tokens per session (457 once invoked), scanned A, original, MIT.

A procedure for running the Logseq-brain evaluation suite in a Linux environment. The suite checks committed files, with free checks available and paid full or single-case evaluations requiring confirmation.

In plain words
What is it for?
It is for checking evaluation setup, running selected cases, and running the full evaluation after approval.
Why use it?
It keeps evaluations in the required environment and prevents an unexpected paid run or a misleading result from uncommitted files.

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

eval 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 today.

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 it actually says

Run the eval suite

evals/README.md is the source of truth. Read it before running anything the first time in a session.

Hard rules

  • Run it only through WSL2 as the logseq-eval user: wsl -d FedoraLinux-44 -u logseq-eval sh /mnt/d/AI/logseq-brain/tools/eval/run.sh …. Never run it on native Windows, and never as the Docker-linked user.
  • It evaluates committed files only. If git status shows uncommitted changes to plugin/, say that they won't be evaluated.
  • Run it through PowerShell, or through Bash with single quotes. wsl.exe heredocs halve backslashes.

Modes

Ask Command args Cost
default / "check" --check free: case schema and tool grants
harness self-test run sh tools/eval/test.sh locally free
one case --case <name> paid, a fraction of a full run
full (no args) paid, ≈ $4–7 of plan usage

Always run --check first. Before any paid mode, state the estimated cost and wait for a yes.

Reading the result

  • Exit 0 means every case passed and the canary is clean. A usage-limit error is not a failure; rerun after the limit resets.
  • A failed case may be rerun once with --case <name>. A pass on the rerun counts as a flake, and a second failure is a real failure.
  • Report per-case pass/fail, both canary lines, and the load-digest and save-basic tool-call figures. Reports land in evals/results/, which is gitignored.
Changes

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.
