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 5.1 | $0.00106 | $0.00862 |
| Opus 5 | $0.00053 | $0.00431 |
| Sonnet 5 | $0.00021 | $0.00172 |
| Haiku 4.5 | $0.00011 | $0.00086 |
Grade A, and why
share-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.

Share Trip
Keywords

Overview
Everway separates two ideas: trip people (travelers on bookings — no account needed) and invites (view-only access to the trip for someone with an email address). Items also have visibility — shared with the trip, or private to whoever added them. This skill picks the right mechanism so "add my mum to the trip" doesn't accidentally email her a login.
Use this skill when: the user wants to add, remove, or look up people on a trip, share access, or change what others can see.
Workflow
Step 1: Understand which of the three they mean
| User says | Mechanism | Tools |
|---|---|---|
| "Add Sam as a traveler / put Sam on the flight" | Trip person | add_trip_person, set_item_people |
| "Let Sam see the trip / share the plan with Sam" | View-only invite (needs email) | invite_viewer |
| "Keep this booking just for me / share it with everyone" | Item visibility | set_item_visibility |
When someone should both travel and see the plan, do both — they're independent.
Step 2: Check the current state
Call list_trip_people (owner, guests, and travelers found in bookings) and list_invites (owner only: pending and accepted invites) before changing anything, to avoid duplicates and to answer "who's on this trip?" accurately.
Step 3: Make the change
Travelers: add_trip_person with displayName (email optional). Rename account-less travelers with rename_trip_person; remove with remove_trip_person (this also detaches them from all items). Owner only.
Attach people to bookings: set_item_people with person ids from list_trip_people — it replaces the list, so include existing ids you want to keep; pass [] to clear.
Invites: invite_viewer sends the email immediately — confirm the address before calling. Revoke pending or accepted invites with revoke_invite; guests who joined by invite are removed this way, not via remove_trip_person.
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.

share-trip is a skill published in the GitHub repository everway-ai/everway-mcp-server (1 stars, last pushed 1mo ago), licensed MIT. It adds 106 tokens to every session and 862 once invoked, about $0.0005 per session on Opus 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 2026-08-31.
