Core Capability88 / 100 — 8 Categories

Functional Suitability
Region Alias Mapping section added with IANA timezone mapping table. preferred_hours parameter added. Covers overlap recommendations, local-time mapping, DST notes, and tradeoff analysis.
12 / 12
100%
Reliability
Region alias normalization now documented. Error handling documented; missing-field prompts present; DST limitation explicitly noted.
11 / 12
92%
Performance & Context
References directory present with guidelines.md and audit-reference.md; good progressive disclosure.
7 / 8
88%
Agent Usability
Workflow clear; Region Alias Mapping table provides clear normalization guidance. Stress-case rules defined; feedback design good.
14 / 16

Human Usability
Description is highly discoverable for distributed team coordinators; forgiveness improved — region aliases now documented.

Security
No credentials required; input validation present; no sensitive data exposure risk.

Maintainability
Clean structure with references/ directory; Region Alias Mapping table makes normalization rules easy to update.

Agent-Specific
Trigger precision good; progressive disclosure via references/; composability still limited — no structured output schema; idempotency strong for pure scheduling logic.

Find meeting window for US, EU, and Asia teams, 60-minute duration

Region aliases (US, EU, Asia) now mapped to representative IANA timezones with notes. preferred_hours parameter available for per-region constraints.

Basic 37/40|Specialized 53/60|Total 90/100
✅A1Output provides suggested meeting windows with region-by-region local times
✅A2Output includes DST assumption notes
✅A3Output includes tradeoff summary for each candidate window
✅A4Output does not fabricate live calendar availability

Variant A✅ Pass
Compare two candidate windows for a US-Australia team with hard constraints

Output completed successfully; compare two candidate windows for a us-australia team with hard constraints case handled within expected scope.

Basic 36/40|Specialized 51/60|Total 87/100
✅A1Output correctly maps candidate windows to local times for both regions
✅A2Output respects the stated hard constraints in the tradeoff analysis
✅A3Output notes that manual confirmation is required before sending invites
✅A4Output does not exceed scope by booking calendar events
Pass rate: 4 / 4

Edge✅ Pass
Request to book a calendar event and send invites automatically

Output completed successfully; request to book a calendar event and send invites automatically case handled within expected scope.

Basic 36/40|Specialized 52/60|Total 88/100
✅A1Skill refuses to book calendar events or send invites
✅A2Refusal message references the correct scope boundary
✅A3No fabricated calendar booking confirmation is produced
✅A4Output stays within the defined scope of scheduling recommendations

Key Strengths

  • Region Alias Mapping section with IANA timezone table resolves the v1 ambiguity gap — US/EU/Asia aliases now explicitly documented
  • preferred_hours parameter added for per-region scheduling constraints, expanding the skill's practical utility
  • Clean two-parameter input model (regions + duration) is minimal and immediately usable
  • Explicit DST limitation in Scope Boundaries prevents false confidence in time calculations
