From da94da82e8257d023bd99d7b5fc8105f9ff64064 Mon Sep 17 00:00:00 2001 From: Rohit Ghumare <48523873+rohitg00@users.noreply.github.com> Date: Tue, 10 Mar 2026 21:47:50 +0530 Subject: [PATCH 1/6] feat: add multi-tier eval engine (skillkit eval) 6-tier evaluation system for comprehensive skill assessment: - Tier 1: LLM quality scoring (G-Eval pattern, 6 dimensions) - Tier 2: Contradiction detection (formal rules + LLM semantic) - Tier 3: Behavioral security (code analysis + taint tracking + LLM) - Tier 4: Sandbox execution testing (Docker, graceful skip) - Tier 5: Dynamic marketplace benchmarks (percentile ranking) - Tier 6: Community signals (freshness, metadata, content health) Works without API keys (heuristic fallback for Tier 1, Tiers 5-6).

engine.ts filters score<0 tiers from overall average so Docker-less machines aren't penalized Duplicate fix: - Add score field to SandboxResult type; store gradeResult.score in each result; compute tier score from average of numeric scores instead of boolean pass rate Nitpick fixes: - Distinguish "Docker unavailable" from "No tests executed" in formatSandboxDetails - Tighten base64 obfuscation regex to require 4-char groups - Only push 'llm' to engines when LLM actually produced findings - Bound \s+ to \s{1,10} in dynamically constructed regexes in contradiction.ts to prevent catastrophic backtracking - Validate cache timestamp with Number.isFinite() in loadCache to reject corrupted cache files with NaN timestamps --- packages/core/src/eval/engine.ts | 5 ++- packages/core/src/eval/reporter.ts | 4 ++ .../src/eval/tiers/behavioral-security.ts | 37 +++++++++++++++---- packages/core/src/eval/tiers/contradiction.ts | 33 ++++++++++++++--- .../core/src/eval/tiers/dynamic-benchmark.ts | 4 +- packages/core/src/eval/tiers/sandbox.ts | 10 +++-- packages/core/src/eval/types.ts | 1 + 7 files changed, 74 insertions(+), 20 deletions(-) diff --git a/packages/core/src/eval/engine.ts b/packages/core/src/eval/engine.ts index 20f46b33..61e257e0 100644 --- a/packages/core/src/eval/engine.ts +++ b/packages/core/src/eval/engine.ts @@ -64,9 +64,10 @@ export class EvalEngine { const results = await Promise.all(tierPromises);
