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 | $0.04298 | $0.04298 |
| Opus 5.5 | $0.01719 | $0.01719 |
| Sonnet 5.5 | $0.00860 | $0.00860 |
| Haiku 4.5 | $0.00430 | $0.00430 |
Grade A, and why
Tackl AGENTS.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 26d 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 — 331 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AGENTS.md
Guidance for AI coding agents working in a Tackl project. Tool-agnostic — read by Cursor, Claude Code, Copilot, Zed, Aider, Gemini CLI and any tool that supports the agents.md convention.
Human-facing docs live in docs/ and README.md; deep-dive
skills live in skills/ (see the end of this file).
The one rule that trips agents up most
Styles are SCSS CSS Modules — there is no CSS-in-JS. styled-components, Div, the
$pad/$mar props, theme getters (getBrand, getGap, …) and @tackl/type do not
exist — never import or recreate them. Write plain JSX tags and style them from the
component's styles.module.scss:
import s from './styles.module.scss';
<section className={s.jacket} data-pad>
<h1 className='t-displayL'>Heading</h1>
</section>
The only layout primitive is Col — a grid child with responsive spans. Pick the tag
with as; it accepts span props ($s…$uber) and every prop of that tag, fully typed:
import { Col } from '@waffl';
<Col as='article' $m='2/6' $l='3/9' className={s.card}>…</Col>
Children that don't need a narrower span don't need Col at all (see the grid section).
Span props only take effect when the Col is a direct child of a <Grid>; Col is a div
by default, so as='div' is never needed.
Imports & aliases
| Import | Use for | Never write |
|---|---|---|
import { breakpoints, mq, alpha, getVw } from '@tackl' |
JS breakpoints, colour/viewport utils | import { Div, getBrand, bp, Col } from '@tackl' (removed / moved) |
import s from './styles.module.scss' |
A component's styles | import * as S from './styles', import styled … |
import Grid, { Col } from '@waffl' |
The grid (default import) and its column (named) | import { Grid } from '@waffl', deep paths, import { Waffl } |
import { theme } from '@theme' |
Tokens in JS (GSAP, inline styles) — var() references |
Hard-coded token values |
import { cx } from '@utils/cx' |
Joining class names | Template-string juggling with undefined |
import { fetchContent, GET_HOME } from '@cms' |
CMS data | importing a CMS adapter folder directly |
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.

Tackl AGENTS.md is an instructions file published in the GitHub repository 12-Studio/Tackl (10 stars, last pushed 25d ago), licensed MIT. It adds 4,298 tokens to every session, about $0.0172 per session on Opus 5.5. 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.
