Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00114 | $0.01674 |
| Opus 5 | $0.00057 | $0.00837 |
| Sonnet 5 | $0.00023 | $0.00335 |
| Haiku 4.5 | $0.00011 | $0.00167 |
Grade A, and why
trip-planner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trip Planner
Overview
This skill turns a loose travel idea ("5 days in Tokyo, mid budget, love food and temples") into a concrete, day-by-day itinerary that is actually executable on the ground. It optimizes four competing dimensions at once:
- Logistics — geographic clustering, transit time, opening hours, reservations, jet lag.
- Budget — flights, lodging, food, activities, local transport, and a buffer.
- Pacing — anchors per day, rest, and travel-day recovery so the trip is enjoyable, not exhausting.
- Highlights — the destination's signature experiences matched to the traveler's stated interests.
Keywords: trip, travel, itinerary, vacation, holiday, road trip, day plan, sightseeing, budget travel, packing, honeymoon, family travel, city break, backpacking.
When to use vs. not
Use this for planning the shape of a trip: which days, which areas, what order, rough costs. This skill does not book anything or guarantee live prices/hours — always tell the user to verify hours, prices, and reservations against official sources near the travel date.
Inputs to gather first
Before planning, collect (ask only for what's missing — infer sensible defaults for the rest):
- Destination(s) and whether it's single-base or multi-city/road trip.
- Dates or duration (and travel season — drives weather, crowds, prices).
- Number of travelers and group type (solo, couple, family with kids' ages, friends, accessibility needs).
- Total budget and currency, plus what it includes (flights? lodging? just on-the-ground?).
- Interests (food, history, nature, nightlife, art, beaches, shopping, adventure).
- Pace preference (packed / balanced / relaxed) and any energy constraints.
- Home origin (for flight time/cost and jet lag) and dietary/mobility constraints.
If the user gives a one-liner, restate your assumptions in one short block and proceed — don't block on a full interview.
Workflow
Follow these steps in order. Each produces a visible artifact for the user.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

trip-planner is a skill published in the GitHub repository JayRHa/AgentSkills (4 stars, last pushed 1mo ago), licensed MIT. It adds 114 tokens to every session and 1,674 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
