SkillRetBench

Dataset summary

SkillRetBench is a benchmark for query-to-skill retrieval: given a natural-language user request, systems must rank or select the correct procedural skill document(s) from a fixed library. The corpus is derived from a real-world production-style agent skill library (501 skills). The benchmark includes 1,250 queries with gold skill identifiers and optional distractors, spanning five evaluation settings (single skill, multi-skill composition, distractors, outdated/redundant, budget-constrained). Packaged baseline experiment results (BM25, dense, hybrid, LLM-style, and SADO-style runs) report standard IR metrics (Recall@k, nDCG@k, MRR, MAP) per setting.

SkillRetBench accompanies the SEFO framework (Self-Evolving Federated Orchestration) and targets research on skill-aware orchestration, large skill libraries, and retrieval under composition and noise.

Dataset structure

The release consists of three JSON artifacts (also listed in croissant.json):

File Description
skill_corpus.json Full skill index: metadata, corpus statistics, and the skills array (one object per skill).
skillretbench_queries.json Benchmark definition: meta (counts, seed, generator) and queries array.
baseline_results.json Aggregated baseline metrics: per-method, per-setting IR scores and a markdown summary table.

skill_corpus.json

  • meta: generated_at (ISO 8601), skills_root, output_path, skill_file_count.
  • statistics: total_skills, skills_per_category, description length stats, token_count_distribution, composition graph stats (skills_with_composition_references, total_composition_edges).
  • skills (array, length 501): each element includes:
    • skill_id (string, canonical id)
    • skill_name (string)
    • description (string, short routing description)
    • trigger_phrases (string array)
    • anti_triggers (string array)
    • korean_triggers (string array; may be empty)
    • category (string)
    • full_text (string, full SKILL.md-derived body)
    • token_count (integer)
    • composable_skills (string array; referenced skill ids)
    • parse_warnings (string array)

skillretbench_queries.json

  • meta: benchmark, generator, corpus_meta, total_queries (1250), counts_by_setting, rng_seed (42).
  • queries (array, length 1250): each element includes:
    • query_id (string, e.g. SS-0001)
    • setting (enum-like string): single_skill | multi_skill_composition | distractor | outdated_redundant | budget_constrained
    • query (string; English and/or Korean natural language)
    • gold_skills (string array; expected skill ids)
    • distractor_skills (string array)
    • budget_tokens (number or null)
    • difficulty (string, e.g. easy, medium)
    • source (string, e.g. trigger_paraphrase)

Query counts by setting

Setting Count
single_skill 400
multi_skill_composition 200
distractor 300
outdated_redundant 150
budget_constrained 200

baseline_results.json

  • timestamp, meta: corpus_skills, queries_total, queries_by_setting, dense_backend (e.g. jaccard_fallback).
  • baselines: nested object — top-level keys BM25, Dense, Hybrid, NaiveLLM, SADO. Under each method, keys match query setting names; each leaf holds metrics: recall@1, recall@3, recall@5, recall@10, ndcg@1, ndcg@3, ndcg@5, ndcg@10, mrr, map (floats).
  • summary_table: pre-rendered markdown table (macro-style summary over settings).

Note: As documented in the artifact, NaiveLLM and SADO entries may be simulated (no live API) for reproducible baselines; see project script run_baselines.py.

Supported tasks

  • skill-retrieval — Rank or classify skills given a query; evaluate with gold gold_skills and IR metrics.
  • information-retrieval — Same retrieval formulation; comparable to passage/tool retrieval with long procedural documents.

Languages

  • English — Majority of skill text and many queries.
  • Korean — Present in korean_triggers, many query strings, and mixed Korean/English skill descriptions.

Dataset creation

Sources

  • Skills were built from Cursor agent SKILL.md files under a single repository’s .cursor/skills tree (501 files), parsed into structured records plus full markdown bodies.
  • Queries were programmatically generated by app.sefo.benchmark.query_generator with fixed rng_seed: 42 for reproducibility.

Methodology (high level)

  1. Corpus build — Parse frontmatter and body; extract triggers, categories, composition edges, and token counts.
  2. Query generation — Instantiate templates and paraphrases aligned to skills and settings (single vs. multi-skill, distractors, outdated/redundant, token budget hints).
  3. Baselines — Run packaged retrievers/rankers (lexical, dense with configured fallback, hybrid, simulated LLM/SADO-style) and aggregate metrics per setting.

Considerations

Biases

  • Corpus domain — Skills reflect one organization’s automation stack (dev tooling, PM, trading, cloud, etc.); frequency and vocabulary are not uniformly representative of all industries or locales.
  • Authoring style — Descriptions follow a consistent “when to use / do not use” pattern; models may exploit format bias rather than deep semantics.
  • Query generation — Synthetic and template-driven queries may over- or under-represent realistic user phrasing compared to production logs.

Limitations

  • Scale — 501 skills is medium-scale vs. ecosystems with 10⁵+ tools; retrieval hardness may not transfer linearly.
  • Gold labels — Defined by benchmark construction rules; edge cases and valid alternative skill sets may exist.
  • Static snapshot — Skill text and ids are frozen for the benchmark revision tied to meta.generated_at in the JSON files.
  • Baseline simulation — Some methods are noted as simulated in-code; compare only under the same harness and seeds.
