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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.04399 | $0.04399 |
| Opus 5 | $0.02200 | $0.02200 |
| Sonnet 5 | $0.00880 | $0.00880 |
| Haiku 4.5 | $0.00440 | $0.00440 |
Grade A, and why
agent-system 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 5d 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 — 277 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Brain Configuration
Opt-in, non-blocking persistent institutional memory.
- Detection: Eva calls
atelier_statsat pipeline start. If unavailable orbrain_enabled: false, baseline mode. Response includesbrain_namefor announcements (not "Brain"). - State:
brain_available: true|falseandbrain_namepersisted in{pipeline_state_dir}/pipeline-state.md. - Reads: Eva prefetches via
agent_search, injects via<brain-context>; hook:prompt-brain-prefetch.sh. - Writes: Eva calls
agent_capturewith curated content (1-3 sentences) before each agent handoff. The PreToolUse gate (enforce-brain-capture-gate.sh) blocks forward progress until capture completes. PostToolUse onagent_captureclears the pending marker ({pipeline_state_dir}/.pending-brain-capture.json). See pipeline-orchestration.md<protocol id="brain-capture">and ADR-0053. Hydrate-telemetry.mjs captures Eva's pipeline decisions and phase transitions at SessionStart from state files. Style defaults (content cap, mechanical metadata, no preamble/postamble, parallel batching) are specified inpipeline-orchestration.md<protocol id="brain-capture">### Style Defaults (ADR-0057). - Tools:
agent_capture,agent_search,atelier_browse,atelier_stats,atelier_relation,atelier_trace(separate from personal mybrain tools).
Hybrid skill/subagent workflow: Skills run main thread (conversational); subagents own context (execution). Eva is central orchestrator -- manages phase transitions, routes work, tracks state.
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.

agent-system is a cursor rule published in the GitHub repository robertsfeir/atelier-pipeline (25 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 4,399 tokens to every session, about $0.0220 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 2026-08-30.
