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.

Security

Grade A, and why

brief 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 149 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Keep your brief current

Your user reads your brief through lemonaid brief show, the inbox's b key, or tmux's prefix+b. Keep Status: and ## Now current so they can tell whose move comes next. Read the whole brief before editing it: its goal, limits, and output still apply.

Find or create your brief

Run lemonaid brief show --self. Your brief is the file attached to your session, normally in ~/.lemons/brief/. If none is attached but an older .z/brief*.md in your place is clearly yours, move it into that folder with a dated name for the work and run lemonaid brief attach --self <file>.

If you have no brief, run lemonaid brief new --self "<what the work is>". It creates a dated file and attaches it to you. Give it a task title, ## Now, and a short ## Goal saying what done looks like. Leave out Parent: when nobody assigned the work. Keep any generated ID line unchanged.

Name the session for the work, with a short area and change, rather than the brief filename or a personal name: lemonaid inbox rename --self "<area and change>". A launch prompt should name the work first, then point to the brief.

Choose the status

Set Status: only when one of the words below applies, and leave it out otherwise. Without one, lemonaid shows your own state: active while you are mid-turn, idle between turns, and deaf or dead if a message sent to you would not be read. lemonaid brief status --self clear removes a status that no longer applies. Older briefs may say working or waiting; both read as no status, and setting either clears it.

Status: contains exactly one word. The reason goes in ## Now. Choose by whose move it is:

Status When to use it
running Nothing waits on your user and you are monitoring a named long process. Put the process and its session:window under ### Running.
review A teammate's approving review on GitHub comes next, rather than your user's or a lemon's. Name the teammate and PR under ### Needs <who>.
blocked Your user can act now: a decision, answer, review, trial, or text to post. Name the move under ### Needs <who>. Asking your user in your final message counts too.
alert Your user's move is needed and harm grows while it waits. Keep this rare; importance alone does not qualify. Say what is getting worse under ### Needs <who>.
merge Only your user's merge remains: reviewer approved, CI green, out of draft, and no conflicts. Check gh pr view <n> --json mergeable says MERGEABLE every time you set this.
approve You reviewed a teammate's PR and recommend your user's approval on GitHub. Name the PR and review doc under ### Needs <who>. A review of a lemon's PR sets no status while it waits on its author or merge.
done Your PR merged or closed, or your output was accepted, and no work or waiter remains.

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.
