What This Report Answers
The three-tier evaluation checks whether the skill:
- is safe to use;
- produces correct answers;
- is discovered and activated when needed;
- helps the agent complete the user's goal and expected workflow; and
- avoids wasted skill and tool usage.
Results at a Glance
| Measure | Claude Code (Baseline → Skill Uplift) | Codex (Baseline → Skill Uplift) |
|---|---|---|
| Overall | 63% → 83% (+20 points) | 65% → 82% (+18 points) |
| Security | 71% → 86% (+14 points) | 71% → 79% (+7 points) |
| Correctness | 86% → 89% (+3 points) | 94% → 94% (±0 points) |
| Discoverability | 41% → 78% (+37 points) | 40% → 69% (+29 points) |
| Effectiveness | 91% → 97% (+6 points) | 93% → 98% (+5 points) |
| Efficiency | 25% → 64% (+39 points) | 24% → 72% (+48 points) |
How to read this table: baseline is the same task attempted without the target skill. Uplift is skill score - baseline score, shown in percentage points.
Example: 47% → 92% (+45 points) means the skill-assisted run scored 92%, 45 percentage points above its 47% no-skill baseline.

Scoring Methodology
<details> <summary>Show dimension definitions, source signals, and thresholds</summary>| Dimension | Question | Scored signals |
|---|---|---|
| Security | Is it safe to use? | security (100%) |
| Correctness | Is the answer correct? | accuracy (100%) |
| Discoverability | Was the right skill loaded when needed? | skill_execution (100%) |
| Effectiveness | Did the skill help complete the task? | goal_accuracy (50%) + behavior_check (50%) |
| Efficiency | Did it avoid wasted tool or skill usage? | skill_efficiency (100%) |
- Dimension bands: PASS at 50% or above; NEUTRAL from 40% to below 50%; FAIL below 40%.
- Overall Tier 3 lift: PASS at +5 points or more; FAIL at -10 points or less; values between those bands are NEUTRAL.
- Overall verdict: PASS only when every configured dimension passes for at least one supported agent. Lift is reported as diagnostic evidence and does not override this gate.
- The 50% attempt pass threshold is a separate per-task gate; it is not the dimension pass threshold.
- Effectiveness is the equal-weight mean of goal completion (
goal_accuracy) and expected workflow adherence (behavior_check). - Token efficiency is a separate report-only signal. It does not change a dimension score or the overall verdict.
Signals present in this run:
security(Security): unsafe operations, secret leakage, and unauthorized access.skill_execution(Skill Execution): whether the expected skill was found and executed.skill_efficiency(Efficiency): routing quality, workspace-aware skill reads, and productive tool use.accuracy(Accuracy): final-answer correctness against the reference answer.goal_accuracy(Goal Accuracy): whether the user's goal was achieved.behavior_check(Behavior Check): whether the expected workflow behavior was followed.
