At a glance

Save flight searches, itineraries, and booked trips to the trips/logs/ directory for future reference.

  • The user asks to log a trip
  • SKILL.md covers File Naming, Document Structure, Status Lifecycle and Reading Past Trips, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Look up past searches

What it does

Trip Log is an agent skill from borski/travel-hacking-toolkit. Save flight searches, itineraries, and booked trips to the trips/logs/ directory for future reference. OPT-IN — use when the user asks to log a trip or look up past searches, or on every search only if the user has said they want automatic logging. Also use to update status when a trip is booked or completed.

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: AI-powered travel hacking and search with cash, points, miles, and award flights. Drop-in skills and MCP servers for Claude, Codex, and OpenCode. The licence is MIT.

When your agent uses it

  • The user asks to log a trip
  • Look up past searches
  • On every search only if the user has said they want automatic logging
  • Update status when a trip is booked

Example prompts

  • “/trip-log”

What it can do on your machine

Read from SKILL.md and the folder at commit db82131. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown and bash).

    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

Trip Log loads about 1.2k tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~80
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:150
    - Do not store `.env` values or account numbers in trip logs.

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); files beside SKILL.md are not scanned.

Trip Log Skill

Save and retrieve flight searches, award analyses, and booked itineraries from trips/logs/. Past entries are a reference library — pull them when planning connected trips, checking what was already searched, or reviewing what was booked and why.

This skill is opt-in. Create entries when the user asks ("log this trip", "save this search"), or automatically only if the user has said they want every search logged. Don't append logging to searches uninvited.

File Naming

trips/logs/YYYY-MM-DD_ORIGIN-DEST_short-label.md
  • YYYY-MM-DD — date the search was run
  • ORIGIN-DEST — airport codes. Multiple destinations: SFO-NRT-HND-SFO
  • short-label — 2–4 word slug describing the trip purpose

Examples:

trips/logs/2026-08-11_SFO-CDG_paris-anniversary.md
trips/logs/2026-07-01_JFK-NRT_japan-ana-first.md
trips/logs/2026-09-02_SFO-OSL_oslo-work-trip-booked.md

Document Structure

Every trip log file uses this structure. Sections marked required must always be present. Others only when relevant.

markdown
---
date_searched: YYYY-MM-DD          # required
origin: XXX                        # required

travel_dates: YYYY-MM-DD to YYYY-MM-DD  # required

tags: [tag1, tag2]                 # freeform

Status Lifecycle

Update the frontmatter status field as the trip progresses:

StatusMeaning
researchedSearch run, no booking yet
bookedAward or cash ticket purchased. Fill in booked_option. Add a ## ✅ BOOKED section at the top.
completedTrip happened. Optionally add notes on actual experience.
cancelledBooking cancelled. Note refund/redeposit outcome.

Reading Past Trips

To surface relevant history, grep the trips/ directory:

bash
# Find all researched (unbooked) trips
grep -l "status: researched" trips/logs/*.md

# Find all trips from a specific origin
grep -l "origin: SFO" trips/logs/*.md

# Find trips tagged with a keyword
grep -rl "anniversary" trips/logs/

# List all trips with their status
grep -h "^status:" trips/logs/*.md

When to Create an Entry

  • When the user asks — "log this", "save this search", "add this to my trips".
  • When a booking is made and the trip is already logged — update status and add the booked section.
  • For booked itineraries that predate the log — backfill with what you know. Set status: booked or status: completed.
  • After every search, only if the user has opted in to automatic logging.

Notes

  • Files live in trips/logs/, which is gitignored — local only, never pushed upstream.
  • Snapshot the user's balances in the frontmatter at search time (from AwardWallet if configured, or whatever the user shares).
  • Do not store .env values or account numbers in trip logs.
