skill-selector

skill-selector is a skill for Claude Code, Codex from Momo2323-ui/claude-orchestra. It costs 106 tokens per session (6,781 once invoked), scanned A, original, MIT.

A selection method for choosing between several skills, MCPs, or connectors that could handle the same task. It compares the candidates against the task, the user’s preferences, and the task’s difficulty.

In plain words
What is it for?
Use it when several tools could handle work such as design, research, lead generation, or code review. It helps rank the options and identify when the choice is uncertain.
Why use it?
It avoids choosing tools randomly, by name, or simply because they are newer. It makes the choice consistent and explains why a particular tool was selected.

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 A, and why

skill-selector scanned grade A 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 12d 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.

Skill Selector — Picking Between Similar Skills Within an Orchestra

"An orchestra can hold many skills that do the same job in different ways. Check them all, try them when the task is complex, and ask the human when you're unsure."

This skill operationalizes that into a transparent scoring + announcement + learning loop.

The problem this solves

Most orchestras have multiple candidates for the same task:

Orchestra Example overlap
DESIGN frontend-design · ui-ux-pro-max · modern-web-design · web-design-engineer · taste-design · 21st.dev (magic)
RESEARCH search-agent · deep-research · market-research · firecrawl · brightdata-plugin · nimble
LEAD GEN Apollo · Apify · brightdata · search-agent · sales-outreach
BUILD code-reviewer · pr-review-toolkit · superpowers:requesting-code-review
CONTENT content-creator · copywriting · marketing-content-creator · book-co-author

Picking randomly = inconsistent quality. Picking by recency = staleness. Picking by name = bias.

This skill picks deterministically, explains why, and asks when uncertain.


When to invoke

  • Automatically: when more than ONE skill in the active orchestra's roster matches the task signal
  • Manually: when the user says "pick the right skill for X" or "which design skill should I use"
  • Inside orchestra-router: as a sub-step after orchestra activation, before player invocation

Skip when: only one skill in the orchestra matches the task (no choice to make), or the user has explicitly named a specific skill ("use ui-ux-pro-max").


The scoring algorithm

For each candidate skill in the target orchestra, compute a score 0–1:

score = (
    relevance_to_task        * 0.35   # how well the skill description matches the task
  + user_vision_alignment    * 0.25   # match against stated vision (e.g. "premium" → max-pro)
  + prior_preference_weight  * 0.20   # pulled from ~/.claude/projects/<x>/memory/feedback
  + complexity_fit           * 0.15   # task complexity vs skill's complexity-fit field
  + skill_freshness          * 0.05   # slight novelty boost for less-used skills
)

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.

skill-selector is a skill published in the GitHub repository Momo2323-ui/claude-orchestra (8 stars, last pushed 1mo ago), licensed MIT. It adds 106 tokens to every session and 6,781 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
