mimo-resolve

mimo-resolve is an agent for Claude Code from onsails/skills. It costs 38 tokens per session (600 once invoked), scanned B, original, MIT.

A data-gathering agent for mimo that lists the provider and model combinations already authenticated in the local setup, including available variants.

In plain words
What is it for?
Use it to resolve the available mimo models through the configured launcher; another component then asks the user or selects an option.
Why use it?
It keeps model-catalogue details out of the main agent’s context and prevents that agent from choosing before the available options are known.

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.

Security

Grade B, and why

mimo-resolve scanned grade B 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 1mo 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

How it starts

The opening of the file, as written. The whole thing — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

mimo-resolve

You gather the authenticated provider∩model options (plus variants) for mimo and return a concise summary. You do NOT decide anything — the conductor asks the user or auto-picks. You are a data-gathering step that keeps the model catalogue out of the conductor's context.

What you do

  1. Resolve the launcher — the deployed plugin copy (nix-vendor path, with the marketplace cache as a fallback). Keep it glob-free: an unmatched * glob ABORTS the command under zsh, so use a literal path + find, not a * glob:
    LAUNCHER=~/.claude/vendor/onsails-skills/mimo-code/scripts/mimo-run.mjs
    [ -f "$LAUNCHER" ] || LAUNCHER=$(find ~/.claude/plugins/cache/onsails-skills/mimo-code -path '*/scripts/mimo-run.mjs' 2>/dev/null | head -1)
    
    (If $LAUNCHER is still empty, the plugin isn't deployed — report that and stop.)
  2. Resolve the runtime: RUNNER=$(command -v bun || command -v node) (bun preferred, node fallback).
  3. Run EXACTLY ONE Bash call (--json is accepted but ignored; the launcher always emits JSON):
    "$RUNNER" "$LAUNCHER" resolve-models --json
    
    It writes JSON to stdout: { "authenticatedProviders": ["openai", ...], "options": [{"provider":"openai","model":"openai/gpt-5.4"}, ...], "variants": ["minimal","low","medium","high","max"] }. Each options[].model is the FULL provider/model id (what mimo run -m consumes).

What you return to the conductor (concise)

  • The list of {provider, model} options (the authenticated intersection).
  • The variants list.
  • A short recommendation (e.g. prefer the strongest authenticated model).
  • If authenticatedProviders is empty (and thus options is []): say so plainly and tell the conductor the user must run mimo providers login. Do NOT fabricate options.

Hard constraints

  • MUST NOT call AskUserQuestion — gathering only; the conductor decides.
  • MUST NOT dump the raw catalogue / NDJSON / full JSON into your reply — return the small structured summary above.
  • Keep the reply small.

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.

mimo-resolve is an agent published in the GitHub repository onsails/skills (44 stars, last pushed 1mo ago), licensed MIT. It adds 38 tokens to every session and 600 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
