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 | $0.00036 | $0.02049 |
| Opus 5 | $0.00018 | $0.01025 |
| Sonnet 5 | $0.00007 | $0.00410 |
| Haiku 4.5 | $0.00004 | $0.00205 |
Grade D, and why
getting-started scanned grade D with 3 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 4d 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.
Strips warnings and disclaimersmediumAnti-refusal
Omitting safety caveats hides risk from the user and is a common jailbreak preamble.
- **Don't lecture about points/miles concepts.** Help them try one thing in the next 30 seconds. Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
**Don't ever offer to collect API keys via chat input.** If the user explicitly insists on pasting in chat, refuse politely and explain that the script is the safe path: keys typed into chat get retained in terminal scro Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 143 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Getting Started Skill
The user invoked this skill explicitly. Help them figure out what's already working, what they're missing, and what to actually try. Critically: do NOT prompt for API keys in chat. Pasting a key into a chat input puts it in terminal scrollback, the local Claude Code session log, and the Anthropic API logs. The toolkit ships a local script that prompts for keys with masked input and writes them straight to the user's shell rc, never going through chat.
Step 1: Detect what's already configured
First detect the user's platform via the Bash tool's environment. If bash is available (macOS, Linux, WSL, Git Bash on Windows), use the bash detection. If you're on native Windows PowerShell with no bash, use the PowerShell detection instead.
Don't print the values; only report SET vs MISSING.
Bash / Zsh (macOS / Linux / WSL / Git Bash)
Use printenv so the loop works in both bash and zsh (Claude Code's bash tool may use either):
for var in SEATS_AERO_API_KEY DUFFEL_API_KEY_LIVE IGNAV_API_KEY AWARDWALLET_API_KEY AWARDWALLET_USER_ID SERPAPI_API_KEY RAPIDAPI_KEY LITEAPI_API_KEY TRIPADVISOR_API_KEY ENTUR_CLIENT_NAME RESROBOT_API_KEY REJSEPLANEN_API_KEY; do
if [ -n "$(printenv "$var")" ]; then echo "SET: $var"; else echo "MISSING: $var"; fi
done
PowerShell (native Windows)
$keys = @('SEATS_AERO_API_KEY','DUFFEL_API_KEY_LIVE','IGNAV_API_KEY','AWARDWALLET_API_KEY','AWARDWALLET_USER_ID','SERPAPI_API_KEY','RAPIDAPI_KEY','LITEAPI_API_KEY','TRIPADVISOR_API_KEY','ENTUR_CLIENT_NAME','RESROBOT_API_KEY','REJSEPLANEN_API_KEY')
foreach ($k in $keys) {
$v = [Environment]::GetEnvironmentVariable($k)
if ([string]::IsNullOrEmpty($v)) { Write-Host "MISSING: $k" } else { Write-Host "SET: $k" }
}
Group the results:
Tier 1 (high-value, missing matters most): SEATS_AERO_API_KEY, DUFFEL_API_KEY_LIVE, IGNAV_API_KEY, AWARDWALLET_API_KEY + AWARDWALLET_USER_ID
Tier 2 (extra sources): SERPAPI_API_KEY, RAPIDAPI_KEY, LITEAPI_API_KEY, TRIPADVISOR_API_KEY
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.

getting-started is a skill published in the GitHub repository borski/travel-hacking-toolkit (650 stars, last pushed 3d ago), licensed MIT. It adds 36 tokens to every session and 2,049 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it D with 3 findings (strips warnings and disclaimers, harvests environment variables, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
