What is finance-trip?

A workflow for finding, reviewing, and tagging financial transactions connected to a specific trip. It can also identify charges that appeared after the trip and summarize the trip's spending.

Use it to total spending for a trip, find transactions from a travel date range, identify late charges, and apply a confirmed trip tag.

It gathers likely trip-related purchases from dates, places, and merchant details, while requiring confirmation before changing transaction data. This helps catch late-posting charges without silently modifying records.

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 Rogue Agent · line 28
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

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	$0.00054	$0.02359
Opus 5	$0.00027	$0.01179
Sonnet 5	$0.00011	$0.00472
Haiku 4.5	$0.00005	$0.00236

Security

Grade A, and why

finance-trip 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 12d 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.

Finance Trip

When to use

The user wants to tag travel transactions for a trip
The user asks "how much did I spend in [place]?"
The user wants to find late-posting charges from a recent trip

Do NOT use if

The "trip" isn't a discrete date range (it's general spending in a category) → use /finance-pulse
The user wants Amazon-specific reconciliation → use /amazon-sync

Track trip expenses by finding transactions in a date range, using location and merchant data to suggest which ones belong to the trip, and tagging confirmed ones. Can re-run to catch stragglers.

Guardrails

Stage writes as a draft. Before any create_tag or update_transaction call (including tag adds via tag_ids), show the user the proposed change (new tag name, or which transactions get which tags) and wait for explicit confirmation. The "Definitely trip" batch-approval flow (Phase 3) is the carve-out — the batch must still be presented first, but per-item confirmation isn't required after the batch is approved in the same turn.
Confirmation is per-turn. A previous "go ahead" does not authorize subsequent batches. Each new batch of writes requires its own confirmation in the same turn.

Phase 1 — Scope the Trip

Read the user profile at ~/.claude/copilot-money/user-profile.md. If the file doesn't exist: run mkdir -p ~/.claude/copilot-money, then copy skills/user-profile.template.md (relative to the copilot-money-mcp repo root) to the profile path. First-time bootstrap may require CWD = repo root for the template read. Check Trip Tracking preferences and any existing trips.
Get trip parameters. Ask the user or infer from context:
- Trip name: e.g., "French Polynesia", "Whistler Weekend"
- Date range: start and end date. If the user says "my Tahiti trip" and you know dates from prior conversation or tagged transactions, use those.
- Location hint: country, city, or region (optional — helps filter)
Check for existing trip tag. Use get_transactions with tag filter to see if a tag already exists for this trip. If it does, this is a re-run to find stragglers — note which transactions are already tagged.

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.
