A tool-evaluation procedure that examines a third-party product, tool, or library from one URL and assesses whether it belongs in a coding workflow or current repository.

Evaluating a tool for use as a command-line program, MCP server, skill, or configuration file, and identifying features or code that could be reused.

It helps separate tools worth adopting from useful parts of their features or code before they are added.

evaluate — Skill for Claude Code by iamneilroberts/claude-skills

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add iamneilroberts/claude-skills --skill evaluate

Per session 297 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

When invoked 2,229 The whole file, excluding the scripts and references it only reads on demand.

Security scan C 1 finding. A grade says what 26 rules found in the file — not that it is safe.

Origin unknown No closer match found in the catalogue.

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 5.1	$0.00297	$0.02229
Opus 5.5	$0.00119	$0.00892
Sonnet 5.5	$0.00059	$0.00446
Haiku 4.5	$0.00030	$0.00223

Security

Grade C, and why

evaluate scanned grade C with 1 finding 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.

The scan reads SKILL.md. This mod also ships 1 executable file (survey.sh), 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

- **Clean up (optional)** — `rm -rf /tmp/evaluate/<slug>` once the report is written,

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
