Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 229 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
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 5.1 | $0.00051 | $0.04904 |
| Opus 5.5 | $0.00020 | $0.01962 |
| Sonnet 5.5 | $0.00010 | $0.00981 |
| Haiku 4.5 | $0.00005 | $0.00490 |
Grade A, and why
round-the-world 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 1mo ago.
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 — 306 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Round the World, Circle Pacific, and Distance-Based Awards
The RTW universe is collapsing. Four programs ended in the last 18 months: ANA Star RTW (June 2025), Singapore KrisFlyer Star RTW (May 2024), SkyTeam Go Round (2024-25), Singapore KrisFlyer Pacific Circle (likely 2024-25). What's left is concentrated in Star Alliance, oneworld, and a few regional distance-based programs.
This skill provides:
- Comprehensive coverage of every active RTW and Circle product
- Historical charts for discontinued programs (so the agent doesn't get fooled by stale blog posts)
- Distance-based regional alternatives that often beat RTW pricing for shorter trips
- Decision rules for picking the right product
Data file: data/rtw-awards.json. Contains 17 programs with confidence markers (VERIFIED / LIKELY) and primary-source citations.
Distance helper: scripts/calc_distance.py (haversine, supports cumulative multi-segment routes, with built-in distance-band lookups for Star Alliance / Qantas / oneworld Global Explorer).
Quick Decision Tree
Want to actually circle the globe?
└→ Want to pay cash? → oneworld Explorer (3-6 continents, online bookable; LIKELY ~$3.6K-$6.9K economy per Upgraded Points 2026; verify on rtw.oneworld.com)
└→ Want to use miles?
├→ Star Alliance RTW (online bookable; Special Business 26k-mile distance band, USD price varies by routing/origin, historically a strong J value)
├→ Lufthansa M&M (fixed 195k Y / 400k J / 540k F miles, phone only)
└→ Qantas oneworld Classic Reward RTW (35k mi cap, 132,400/318,000 Y/J pts)
Want to circle the Pacific Rim only?
├→ Star Alliance Circle Pacific (online via member; 22k or 26k mi)
└→ oneworld Circle Pacific (travel agent only)
Want a multi-carrier oneworld trip but not full RTW?
├→ Cathay Asia Miles oneworld multi-carrier (13 distance bands; cheapest J at 60k mi <1000mi)
├→ JAL Mileage Bank multi-carrier (10 bands; sweet spot 25k Y / 48k J <4000mi)
└→ Qantas oneworld Classic (separate from its RTW config)
Just want regional flights cheap?
├→ Aeroplan distance-based (NA: 6k Y starting <500mi; Atlantic: 32.5k Y starting <4000mi)
└→ Iberia Plus Avios (intra-Europe: 3,500 Y under 650mi off-peak)
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.
- 1mo ago First seen · 306 lines · 51 tokens per session scan A 9ba6c9d11521
round-the-world is a skill published in the GitHub repository borski/travel-hacking-toolkit (710 stars, last pushed 6d ago), licensed MIT. It adds 51 tokens to every session and 4,904 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
