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

atelier 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 12d 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.

Atelier — design intelligence (El DT)

Router unificado. Upstream: Impeccable vendoreado vía tools/atelier/.

DT session gate (El DT)

Before writing files in the repo:

  1. Read vitals/ops/session.yaml. If missing or operator.id empty → stop and ask the user to run /yo.
  2. Design context canonical path: .agents/design-context.md (not separate PRODUCT.md/DESIGN.md unless exporting).

DT context loader

Run once per session (not per sub-command):

node tools/atelier/generated/scripts/context.adapter.mjs

Optional target for monorepos:

node tools/atelier/generated/scripts/context.adapter.mjs --target <path>
  • If output reports NO_DESIGN_CONTEXT, stop and follow tools/atelier/generated/references/init.md.
  • Imports .agents/product-marketing.md when present (see design-context skill).
  • UPDATE_AVAILABLE: offer /atelier actualizar (DT maintainer sync), then continue.

Register references (DT paths)

Register File
Brand (marketing, landing, portfolio) tools/atelier/generated/references/brand.md
Product (app, dashboard, tool) tools/atelier/generated/references/product.md

Map register from design-context sections — do not create duplicate PRODUCT.md/DESIGN.md.

DT-native subcommands

Command Action
/atelier select [brief] ruby scripts/dt-design-select.rb "brief" + skill design-selector
/atelier read skill design-read — V/M/D dials

When building surfaces, load one tactical guide: .cursor/skills/design/{skill}/GUIDE.md (see table).

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.
