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 | $0.00063 | $0.01366 |
| Opus 5 | $0.00032 | $0.00683 |
| Sonnet 5 | $0.00013 | $0.00273 |
| Haiku 4.5 | $0.00006 | $0.00137 |
Grade A, and why
size-cards 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.
How it starts
The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Size cards
You size planning-board cards for a team lead: read each card, decide what it weighs by the rubric below, show the lead the table, and write the sizes back with update_card. The board sums sizes as points (S=1, M=2, L=4, XL=8) against each person's weekly capacity, so consistency matters more than precision: the same shape of card must always get the same size.
Sizing happens AFTER the fact, in a pass like this one — not card by card as work is planned. A card nobody has sized is not invisible meanwhile: the board weighs it as M, the middle of its own record. So the value of a pass is in the cards that are NOT M — the ones that would otherwise be under- or over-counted — and a card you would call M is a card the board already has right.
This is judgement work, card by card. Never derive a size from the length of the description, the team, or the kind of card by a rule; never write code that assigns sizes. Read the card and decide.
Procedure
- Find the cards. Use the aeman MCP
list_cards:- a team:
list_cards view=team team=<key>— read the keys fromget_board(metadata.teams;""is the no-team group); - a person:
list_cards view=me user=<login>; - a week on the Triage board:
list_cards view=triage team=<key>, then keep the cards whosestatus.triageWeekis the Monday asked for; - the whole backlog of a team:
list_cards view=backlog team=<key>. Keep the cards with nospec.size, unless the lead asked to re-size everything. Skip review cards (spec.reviewOfset) — a review is S by definition and the board already weighs an unsized one as S, so a pass over them changes nothing — and skip process turns (spec.taskset) unless asked: a turn is planned work of its process and is normally S or M.
- a team:
- Read what you need. The listing is the board's row shape: title, team, zone, assignees, kind. When a title alone does not say what the work is, call
get_cardfor the description — but do not open every card: a one-line card with no description is almost always S, and the rubric says so. - Size every card by the rubric. Write one line per card for the lead:
uid — title — size — why, where why names the concrete deliverable in the card's own words (at most twelve words). Cards you are unsure about, mark with?and say what would decide it. - Show the table and STOP. Do not write anything until the lead has read it and said which sizes stand. They may change some; their word wins.
- Write the sizes the lead confirmed:
update_card uid=<uid> size=<S|M|L|XL>, one call per card. Report how many were written and the points total per 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.

size-cards is a skill published in the GitHub repository aenix-io/aeman (31 stars, last pushed today), licensed Apache-2.0. It adds 63 tokens to every session and 1,366 once invoked, about $0.0003 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 2026-09-09.
