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 | $0.00057 | $0.00607 |
| Opus 5 | $0.00028 | $0.00303 |
| Sonnet 5 | $0.00011 | $0.00121 |
| Haiku 4.5 | $0.00006 | $0.00061 |
Grade A, and why
dewey 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 7d 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.
What it actually says
Dewey — Classifier
Assigns taxonomy level (L1-L6) to each document, enforces required documents per project level.
Document Hierarchy (L1–L6)
| Level | Type | Examples |
|---|---|---|
| L1 | Contracts | contracts/openapi/*.yaml, contracts/asyncapi/*.yaml |
| L2 | Product Canon | docs/VISION.md, docs/PRD.md, docs/ROADMAP.md, docs/FEATURES.md |
| L3 | Engineering Canon | docs/ARCHITECTURE.md, docs/ADR/, docs/SAGA/, docs/TEST_CASES.md |
| L4 | Derived | docs/REFERENCE.md, docs/DEV_GUIDE.md, docs/STATUS.md |
| L5 | Artifacts | Generated files (API docs, changelogs, diagrams) |
| L6 | Auxiliary | README.md, CONTRIBUTING.md, LICENSE, templates |
What it does
- Classifies every document by type and level
- Determines project maturity level (L1-L3 based on required docs present)
- Validates required documents exist for detected level
Usage
# Via Chronos orchestrator
chronos --path . --preset standard
# Direct invocation
python -m chronos.agents.dewey --path .
Output Format
[warning] missing: Required L2 document missing — docs/ROADMAP.md
[info] classified: docs/ARCHITECTURE.md → L3 Engineering Canon
[info] project_level: L2 (Product Canon) — 3/4 required docs present
Required Documents per Level
| Level | Required |
|---|---|
| L1 | At least 1 contract file (OpenAPI/AsyncAPI/JSON Schema) |
| L2 | VISION.md, PRD.md, ROADMAP.md |
| L3 | ARCHITECTURE.md, ADR/ directory |

Integration
Loaded by Chronos as part of standard and full presets.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

dewey is a skill published in the GitHub repository bestdeejay-design/agent-skills (5 stars, last pushed 3d ago), licensed MIT. It adds 57 tokens to every session and 607 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 2026-09-03.

workflow
Use when a task is too large for turn-by-turn orchestration and should run through the big-task workflow lane: system-wide changes, large migrations, repo-wide audits, high-confidence verification, or tasks explicitly asking to run a workflow. Claude Code uses native dynamic workflows; Codex, OpenCode, and Grok use…
