Skill Eval Improve
Arenukvern/mcp_flutter
Improves Agent Skills via validate → rule-based eval cases → plugin-eval → prompt evals → bounded edits with held-out gates.
Validate the output of any installed skill against an assertion manifest — word counts, required patterns, forbidden phrases, required sections, source citation.

What it does
Aeon Skill Evals is an agent skill from BankrBot/skills. Validate the output of any installed skill against an assertion manifest — word counts, required patterns, forbidden phrases, required sections, source citation. Detects regressions by diffing vs prior runs (NEWFAIL / NEWPASS / CHRONIC / STABLEFAIL). Bootstrap mode generates a starter manifest from a skill's recent successful runs so manifests aren't written speculatively. Triggers: "evaluate this skill's output", "check skill X for regressions", "bootstrap evals for Y", "did this skill output pass quality gates".
Its SKILL.md is about 660 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `catalog.json`).
It sits in Testing & QA, covering Agent evaluation and testing, LLM evaluation and Quality gates. The repository describes itself as: Bankr Skills equip builders with plug-and-play tools to build more powerful agents.
When your agent uses it
- Tasks that involve Agent evaluation and testing
- Tasks that involve LLM evaluation
- Tasks that involve Quality gates
Example prompts
- “s recent successful runs so manifests aren”
- “evaluate this skill”
- “check skill X for regressions”
- “/aeon-skill-evals”
What it can do on your machine
Read from SKILL.md and the folder at commit dc47eed. 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 (its code samples are yaml).
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
Aeon Skill Evals loads about 660 tokens when it runs. Until then it costs about 135 tokens; SKILL.md has 199 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 199 words (~660 tokens).
“Quality net for installed skills. Each skill can declare an assertion manifest; outputs are checked against it; failing assertions surface regressions and route concrete fixes.”
