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.
npx agentmods add instructions/sledmonkey/getflightplan/claude-mdgit clone --depth 1 https://github.com/sledmonkey/getflightplanWhat 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 | $0.01109 | $0.01109 |
| Opus 5 | $0.00554 | $0.00554 |
| Sonnet 5 | $0.00222 | $0.00222 |
| Haiku 4.5 | $0.00111 | $0.00111 |
Grade A, and why
getflightplan CLAUDE.md 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 yesterday.
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.
This is a copy
100% identical to getflightplan AGENTS.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Intent registry
This repo participates in the team intent registry (MCP server: flightplan).
- Before starting non-trivial work, call
post_intent. The test: will the work change behavior, defaults, or contracts another agent would encounter — or, for pure investigation, would the findings save the next agent an hour? Yes to either → post; Q&A and typo-level fixes, no. Send a one-paragraph summary (what + why),kind(build, orexplore/spikefor throwaway investigation), andtouchesglobs for the areas you expect to change. Keep the returned id for later. Forrepo, usegetflightplan(pinned in.flightplan.toml; do not derive it) — every agent on this repo must use the same name or collision checks silently miss each other. The response may includecontext: recent completed work relevant to your task — read those outcomes before starting; the surprises and dead ends in them are load-bearing. - If the response includes overlaps at level
warn, check what the overlap is before pausing. Two cases need no confirmation — mention the overlap and keep going: the overlapping intent is the very work you were asked to act on (reviewing it, verifying it, following up on it), or your task is read-only. Otherwise, tell your user who is doing what and which globs collide, and ask how to proceed before continuing.fyi/nudgelevels: mention briefly and keep going. - If the work changes shape or runs long, call
update_intent: revise the summary/touches when scope grows (collision checks run against them — stale globs miss real collisions), or call with just the id to renew the TTL on work spanning more than a day. The response includes freshoverlaps— the same collision check as posting, glob-based — and awarnthere gets the same treatment as awarnat post time. - When the work finishes or is abandoned — including when the session is
wrapping up — call
complete_intentwith a one-paragraph outcome: what actually changed, anything surprising, approaches tried and rejected, anything deliberately left in place. If awarnoverlap changed how the work went (coordinated, narrowed scope, proceeded anyway), say which. Attach the git facts you already know:filesactually changed (git diff --name-only),commitscreated, anduncommitted: trueif any of the work is not yet committed — that flag is what lets other agents' collision checks warn loudly instead of quietly. Completing an intent ends the slice, not the session: follow-up work after a complete that changes behavior, defaults, or contracts gets a fresh post — "same session" doesn't exempt it. - When you learn declared-uncommitted work has landed, call
mark_intent_landedwith that intent's id (and the commit SHAs if you know them): until someone says so, the registry keeps warning everyone who touches those paths. - Re-check for collisions whenever your picture of in-flight work may be
stale — posting checks once, and it goes stale over a long session.
Re-check moments: a file changed between your read and your edit, or an Edit
fails on text you just read — someone's work landed under you; before editing
a shared doc or artifact you didn't create this session; when resuming after
a handoff from another agent; and before touching files named in an earlier
warn. The cheapest re-check isupdate_intentwith just your intent id (renews the TTL, returns freshoverlaps); uselist_intents(passoverlapsglobs, plussummaryfor a semantic check, orq/sincefor history) when you have no open intent or are scoping new work. - When a decision gets resolved in conversation (an approach chosen, an
alternative rejected, a direction set), record it the moment it settles:
post_intentwithkind: "decision", the question as the summary, and the resolution inoutcome— what was decided, what was rejected, and why. One call; no touches, no completion later. Decisions never collide and become searchable team memory. Decisions are also the correction mechanism: completed outcomes are immutable, so if one later proves wrong, post a decision citing what actually held. - The registry is advisory and must never block work: if its tools are missing
or error, proceed with the work, and tell your user once that they can run
uvx getflightplan install(see getflightplan.com) to join this repo's registry.
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.
