A command that checks an implementation against stated acceptance criteria, meaning the conditions that define whether the work is complete. It can report a pass or fail, a score, or category-based results.

Use it to run relevant tests, assess feature completion or quality, and produce an evaluation report with criterion-level results.

It turns a broad code review into a documented check against specific requirements and evidence.

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.

Model	Per session	Once invoked
Fable 5	$0.00005	$0.00445
Opus 5	$0.00003	$0.00222
Sonnet 5	$0.00001	$0.00089

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 2d 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.

Origin

This is a copy

100% identical to eval — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Eval Command

Evaluate implementation against acceptance criteria: $ARGUMENTS

Your Task

Run structured evaluation to verify the implementation meets requirements.

Evaluation Framework

Grader Types

Binary Grader - Pass/Fail
- Does it work? Yes/No
- Good for: feature completion, bug fixes
Scalar Grader - Score 0-100
- How well does it work?
- Good for: performance, quality metrics
Rubric Grader - Category scores
- Multiple dimensions evaluated
- Good for: comprehensive review

Evaluation Process

Step 1: Define Criteria

Acceptance Criteria:
1. [Criterion 1] - [weight]
2. [Criterion 2] - [weight]
3. [Criterion 3] - [weight]

Step 2: Run Tests

For each criterion:

Execute relevant test
Collect evidence
Score result

Step 3: Calculate Score

Final Score = Σ (criterion_score × weight) / total_weight

Step 4: Report

Evaluation Report

Overall: [PASS/FAIL] (Score: X/100)

Criterion Breakdown

Criterion	Score	Weight	Weighted
[Criterion 1]	X/10	30%	X
[Criterion 2]	X/10	40%	X
[Criterion 3]	X/10	30%	X

Evidence

Criterion 1: [Name]

Test: [what was tested]
Result: [outcome]
Evidence: [screenshot, log, output]

Recommendations

[If not passing, what needs to change]

Pass@K Metrics

For non-deterministic evaluations:

Run K times
Calculate pass rate
Report: "Pass@K = X/K"

TIP: Use eval for acceptance testing before marking features complete.

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.

eval is a command published in the GitHub repository tpavanipradeep/everything-claude-code (103 stars, last pushed 5mo ago), licensed MIT. It adds 5 tokens to every session and 445 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to eval, differing in 0 lines, and is treated as a copy.
