What it does

Time Zone Planner is an agent skill from aipoch/medical-research-skills. Plan cross-time-zone meeting windows for distributed teams, providing region-by-region local time mappings and tradeoff analysis for scheduling decisions.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `POLISH_CHANGELOG.md`, `references/audit-reference.md` and `references/guidelines.md`).

The repository describes itself as: Hundreds of agent skills for medical research, including protocol design, data analysis, evidence insights, and academic writing. The licence is MIT.

Example prompts

  • “/time-zone-planner”

Requirements

  • Python 3

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Confirm the participant regions, meeting duration, preferred local-hour ranges, and any hard constraints.
  2. Check whether the request is for a quick overlap recommendation or a full tradeoff analysis.
  3. Use the packaged script for baseline scheduling output; for complex requests, provide a manual comparison table with stated assumptions.
  4. Return suggested meeting windows, region-by-region local times, and the tradeoffs behind the recommendation.
  5. If timezone details or availability constraints are missing, stop and request the minimum missing fields.

What it can do on your machine

Read from SKILL.md and the folder at commit 686e09d. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Time Zone Planner loads about 1.2k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 43 tokens; SKILL.md has 542 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~43
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

Time Zone Planner

Structured cross-time-zone meeting planning for distributed teams.

Quick Check

bash
python -m py_compile scripts/main.py
python scripts/main.py

When to Use

  • Use this skill when planning meeting windows across multiple regions or time zones.
  • Use this skill when comparing candidate windows and tradeoffs for distributed team scheduling.
  • Do not use this skill for calendar booking, live availability checking, or travel/legal decisions.

Workflow

  1. Confirm the participant regions, meeting duration, preferred local-hour ranges, and any hard constraints.
  2. Check whether the request is for a quick overlap recommendation or a full tradeoff analysis.
  3. Use the packaged script for baseline scheduling output; for complex requests, provide a manual comparison table with stated assumptions.
  4. Return suggested meeting windows, region-by-region local times, and the tradeoffs behind the recommendation.
  5. If timezone details or availability constraints are missing, stop and request the minimum missing fields.

Usage

text
python scripts/main.py
# Input: {"regions": ["US", "EU", "Asia"], "duration": 60}

Parameters

ParameterTypeRequiredDefaultDescription
regionslist[string]Yes—Region set, e.g. ["US/Eastern", "Europe/London", "Asia/Shanghai"]
durationintegerYes—Meeting duration in minutes
preferred_hoursobjectNo—Per-region preferred local hour ranges, e.g. {"US/Eastern": [9, 17]}

Region format: Use IANA timezone names (e.g., US/Eastern, Europe/London, Asia/Shanghai) for precise mapping. Short aliases like "US" or "EU" are accepted but will be mapped to a representative timezone with a note.

Region Alias Mapping

AliasMapped ToNote
USUS/EasternRepresentative only; specify sub-region for accuracy
EUEurope/LondonRepresentative only; specify country for accuracy
AsiaAsia/ShanghaiRepresentative only; specify city for accuracy

Output

  • Suggested meeting windows by region
  • Local-time mapping for each included region
  • DST assumption notes when applicable
  • Tradeoff summary for each candidate window

Scope Boundaries

  • This skill supports scheduling recommendations, not calendar booking.
  • This skill does not validate current DST status from live internet sources.
  • This skill does not decide business priority between teams without user-supplied rules.
  • Manual confirmation is required before sending invites.

Stress-Case Rules

For multi-constraint requests, always include these explicit blocks:

  1. Assumptions
  2. Hard Constraints
  3. Recommended Window
  4. Tradeoffs
  5. Risks and Manual Checks
Show full SKILL.md (217 more words)Show less

Error Handling

  • If required inputs are missing, state exactly which fields are missing and request only the minimum additional information.
  • If the task goes outside the documented scope, stop instead of guessing or silently widening the assignment.
  • If scripts/main.py fails, report the failure point, summarize what still can be completed safely, and provide a manual fallback.
  • Do not fabricate live calendar availability or confirmed participant agreement.

Input Validation

This skill accepts: a list of participant regions and a meeting duration for cross-timezone scheduling recommendations.

If the request does not involve cross-timezone meeting planning — for example, asking to book calendar events, check live availability, make travel arrangements, or provide legal scheduling advice — do not proceed with the workflow. Instead respond:

"time-zone-planner is designed to recommend meeting windows across time zones for distributed teams. Your request appears to be outside this scope. Please provide a region list and meeting duration, or use a more appropriate tool."

References

Response Template

Use the following fixed structure for non-trivial requests:

  1. Objective
  2. Inputs Received
  3. Assumptions
  4. Workflow
  5. Deliverable
  6. Risks and Limits
  7. Next Checks

If the request is simple, you may compress the structure, but still keep assumptions and limits explicit when they affect correctness.
