Skillware-Bench

Benchmark Overview

Skillware-Bench evaluates models across an empirical 16-layer Progressive Tiered Ablation Benchmark (4 real-world crucibles x 4 progressive difficulty tiers = 16 layers, 32 evaluated conditions per model). It contrasts unconditioned code generation (Vanilla Baseline) against governed skill execution (Skillware Equipped).

Across the complete 23-model evaluation roster (spanning 11 sovereign and commercial model families), the benchmark comprises 368 total layers and 736 live experimental test conditions.

Figure 25 — Capability Compression Heatmap Across the 23-Model Fleet

Figure 25. Capability compression heatmap across all 23 evaluated models and 4 enterprise crucibles (736 live experimental conditions). Cells display exact empirical pass rate lift (Δ percentage points) when equipping baseline models with Skillware execution manifests. Across the fleet, Skillware produces a +10.1% grand aggregate pass lift (from 81.5% to 91.6% fleet success, 337/368 vs 300/368 tasks passed). Uplift is heavily concentrated in complex multi-step stateful workflows: Office Mail achieves a fleet lift of +22.8% (68.5% → 91.3%), and Companies House records +12.0% (75.0% → 87.0%). Compact open-weight models achieve the largest single gains—most notably Meta Llama 4 Maverick (+56.2% lift, from 37.5% to 93.8% across 16 tasks)—effectively closing the capability gap with unassisted frontier models at a fraction of inference cost. Models are sorted by Grand Mean lift descending, then vanilla baseline.

Table 7 — Four-Axis Master Operational Summary

Table 7. Four-axis master benchmark summary across 12 representative frontier and sovereign architectures (384 live conditions). Models are sorted by Skillware Accuracy descending within capability tiers. Pass lift reflects delta percentage points over unassisted Vanilla baselines. Token reduction captures total prompt and completion token savings. Speedup denotes wall-clock runtime acceleration. Code Debugging Eliminated denotes total elimination of ad-hoc bash and python script repair loops (464 loops fleet-wide in Vanilla vs 0 in Skillware).

Key Empirical Findings

1. Small Sovereign Models + Skillware Match or Outperform Frontier LLMs Alone: Compact open-weight models (e.g. Qwen 3.6 35B, Gemma 4 31B, Nemotron 3.5 Lightning) equipped with deterministic skills consistently achieve higher pass rates (14-16/16) and lower latency than unassisted frontier APIs operating in Vanilla mode (e.g. Claude Sonnet 5, GPT-6 Luna, Grok 4.7). See Frontiers vs Small Models Deep-Dive.

Figure 12. The cost–capability frontier across eight representative models from the benchmark fleet. Each dashed trajectory connects a model from its Vanilla baseline (ochre) to its Skillware equipped operating point (emerald green). The Skillware frontier dominates the Vanilla fleet everywhere, shifting up (higher accuracy across 16 benchmark layers) and to the left (lower operational token cost per task).

2. Elimination of the Base64 MIME Attachment Failure Trap: Across nearly all frontier models in Vanilla mode, extracting binary email attachments caused catastrophic failures, triggering 5 to 11 debug attempts and burning tens of thousands of tokens. Skillware resolved attachments in 2 to 3 turns without executing any workspace scripts. See Behavioral Contracts Analysis.

Figure 11. Latency anatomy of a complex reference workflow (Office Mail Tier 2). JIT context excision shrinks prefill latency from 4.1 s to 0.7 s, compact model routing shortens decode from 6.2 s to 3.4 s, and deterministic host validation eliminates speculative error loops: end-to-end median latency falls from 14.2 s to 6.3 s (−55.6%). Time to first token (TTFT) collapses from 1.9 s to 0.4 s.

3. 100% Code Debugging Overhead Eliminated: Vanilla models spent 464 iterations debugging raw Python scripts across the benchmark. Skillware completely eliminated this burden, reducing debugging iterations to zero. See Token Economics Deep-Dive.

Governed Execution via Skillware

Skillware (arpahls/skillware) is the open runtime framework for modular, self-contained AI agent skills. It replaces unstructured, unconditioned code synthesis and prompt-injected manuals with typed OpenAPI/JSON schemas, deterministic JIT execution handlers, runtime capability boundaries, and strict constitutional safety gates.

Cryptographic Receipts via AURA

Every benchmark evaluation produces a verified cryptographic receipt anchored via the AURA attestation spine. Receipts contain a SHA-256 causal DAG hash over all executed turns, tool invocations, token metrics, and scoring outputs to ensure tamper-evident verification.

The complete canonical execution reports for all 23 evaluated models are tracked in benchmarks/reports/. Verify any model's receipt instantly without API keys:
