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.

SkillSpector: 4 findings, 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 →

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 | $0.00044 | $0.02644 |
| Opus 5.5 | $0.00018 | $0.01058 |
| Sonnet 5.5 | $0.00009 | $0.00529 |
| Haiku 4.5 | $0.00004 | $0.00264 |
Grade A, and why
chase-travel 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 — 213 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Chase Travel Portal Search
Search the Chase Ultimate Rewards travel portal for flights and hotels via Patchright. Returns cash prices, UR points pricing, Points Boost offers, and Chase Edit hotel benefits.
Requires Patchright (undetected Playwright fork). Chase blocks standard Playwright and agent-browser.
Must run headed (headless=False). Chase detects headless browsers. On macOS, a Chrome window briefly appears. For background operation, use Docker.
Prerequisites
pip install patchright && patchright install chromium
Or use Docker (no local install needed):
docker pull ghcr.io/borski/chase-travel:latest
# or build locally:
docker build -t chase-travel skills/chase-travel/
When to Use
- Compare UR portal pricing against cash and award prices
- Check Points Boost offers (1.5x to 2.0x cpp on select bookings)
- Find Chase Edit hotels with $100 property credit + daily breakfast
- Compare pay-with-points vs transfer-to-airline value
When NOT to Use
- Completing purchases. Find flights and hotels only. Do not book.
- Non-Chase cards. This skill requires a Sapphire Reserve or Sapphire Preferred card.
Card Selection
The script automatically selects the Sapphire Reserve card from the account selector (dynamic Points Boost pricing on travel; ~1.5-2.0 cpp typical on CSR but not a guaranteed floor; Edit hotels). Falls back to Sapphire Preferred if no Reserve found. Only these cards show Edit hotel benefits and travel portal pricing.

What ships with it
4 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.

chase-travel is a skill published in the GitHub repository borski/travel-hacking-toolkit (774 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 2,644 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.
