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 | $0.04965 | $0.04965 |
| Opus 5.5 | $0.01986 | $0.01986 |
| Sonnet 5.5 | $0.00993 | $0.00993 |
| Haiku 4.5 | $0.00496 | $0.00496 |
Grade A, and why
design-engineering 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 9d 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.
AGENTS.md
Repo-level operating guidance for AI agents working in this codebase. Pairs with SOUL.md, which carries identity (voice, stance, taste lineage). This file is the what / how; SOUL.md is the who / why. Read both on cold start.
What this repo is
A single agent skill packaged as a skill graph — one root SKILL.md (the Map of Content) plus a references/ folder of atomic, wikilinked nodes organised into themed subfolders (philosophy/, motion/, sound/, svg/, diagram/, launch-video/, typography/, surface/, components/, layout/, anti-patterns/, meta/), an evals/ folder for Perplexity-style Step-0 evals, and a scripts/ folder with the three tools the knowledge needs (sound-family.mjs, sound-sheet.mjs, svg-flipbook.mjs). A sibling agents/ directory ships ten workflow subagents that map to the highest-value design-engineering tasks. The skill encodes design engineering knowledge.
Since v2.0.0 the repo is organised around four primitives: Knowledge (skills/design-engineering/, Agent Skills spec), Package (root plugin.json, Agent Plugins v1.0.0), Runtime (agent/ + evals/, the eve framework), and Client extensions (agents/, commands/, and the per-host manifest dirs, declared under reverse-domain namespaces in plugin.json extensions). The knowledge is canonical; everything else delivers it. agent/skills/ is generated by scripts/sync-skills.mjs — never edit it; edit skills/design-engineering/ and re-sync.
The graph is intentionally Obsidian-compatible: installers can open this repo as a vault to navigate clusters in the graph view and edit nodes in place. The recommended companion is kepano/obsidian-skills. Preserving that compatibility is a constraint on every edit (see rule 6).
When editing this repo
1. Edit atomic nodes, not the SKILL.md. The SKILL.md is a map. Real content lives in references/<theme>/. If you're adding new knowledge, drop the atomic node into the matching themed subfolder and link it from that theme's MOC-<theme>.md. Only update SKILL.md when adding a new top-level topic (which means adding a whole new theme folder).
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.

design-engineering AGENTS.md is an instructions file published in the GitHub repository AgentsORG/design-engineering (32 stars, last pushed 10d ago), licensed MIT. It adds 4,965 tokens to every session, about $0.0199 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 2026-08-30.
