The repository describes itself as: SkillsBench evaluates how well skills work and how effective agents are at using them. The licence is Apache-2.0.
When your agent uses it
- Creating benchmark tasks
- Understanding repo structure
- Preparing PRs for task submission
Example prompts
- “/skillsbench”
Requirements
- Docker
What it can do on your machine
Read from SKILL.md and the folder at commit 9a1f4dd. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
uv
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
github.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skillsbench loads about 426 tokens when it runs. Until then it costs about 40 tokens; SKILL.md has 63 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Quick Workflow
# 1. Install and initialize a task
# v1.1 docs target BenchFlow 0.6.2; uv installs the current stable CLI.
uv tool install benchflow
bench tasks init <task-id>
# 2. Write files (see CONTRIBUTING.md for templates)
# 3. Validate
bench tasks check tasks/my-task
bench eval run --tasks-dir tasks/my-task --agent oracle --sandbox docker # Must pass 100%
# 4. Test with agent (with skills)
bench eval run --tasks-dir tasks/my-task --agent claude-agent-acp \
--model <model> --skill-mode with-skill \
--skills-dir tasks/my-task/environment/skills/
# 5. Test WITHOUT skills
bench eval run --tasks-dir tasks/my-task --agent claude-agent-acp \
--model <model> --skill-mode no-skill
# 6. Submit PR (see PR template)Task Requirements
- Realistic workflows people actually do
- Measurably easier with skills than without
task.mdprompt body andoracle/solve.shmust be human-authored- Deterministic, outcome-based verification
- Skills must be generalizable and reusable
