What it does
Self Verification is an agent skill from A-EVO-Lab/a-evolve. Verification patterns to confirm task completion before submitting. Read this before calling submit().
Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: The official repository of "Position: Agentic Evolution is the Path to Evolving LLMs".
Example prompts
- “/self-verification”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
- Re-read Requirements
- Verify Each Requirement
- Check Your Assumptions
- Common Pitfalls
What it can do on your machine
Read from SKILL.md and the folder at commit 18ba996. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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
Self Verification loads about 365 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 188 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 188 words (~365 tokens).
“Before calling submit(), systematically verify your solution:”
