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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00094 | $0.00838 |
| Opus 5 | $0.00047 | $0.00419 |
| Sonnet 5 | $0.00019 | $0.00168 |
| Haiku 4.5 | $0.00009 | $0.00084 |
Grade A, and why
omd-slim 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.
What it actually says
/omd-slim — 精益审计(先债后瘦)
两步:先把已知欠账(你主动留的 ponytail: 捷径)收成台账,再让车队找你没意识到的过度工程。两者不同——债是你故意留的,过度工程是意外长出来的。
Pass 0 — debt 台账(先记已知债)
跑 bun run scripts/omd-debt.ts [--paths "src,scripts"]:纯 grep 扫全仓 // ponytail: <天花板>, <升级触发> 标记,收成 ledger(缺升级触发的标 - = rot 风险)。零 LLM。让"以后再说"不烂成"永远不说"。这是已知债的账,不判对错,只收拢。
Pass 1+2 — 过度工程专审(经 dag_slim)
调 omd MCP dag_slim(可能带 mcp__omd__ 前缀;未加载先 ToolSearch "dag_slim"),scope 可选收窄。异步三段式:dag_slim(scope?) → dag_status 轮询 → dag_result 取报告路径自己 Read。车队按 global-first 两遍法(系统级先跑,-50% 在这):
Pass 1 — global(系统级):跨文件找 —
dedup:同一逻辑手写在 N 处 → 一个共享 util(最大赢面)collapse:一个概念的并行实现 → 合并成一个layer:没人需要的整层/包装/间接 → 删掉这层couple:局部"最小"选择造成的耦合/重复 → 全局一致的替代
Pass 2 — local(逐 hunk):delete: 死代码/用不上的灵活性 · stdlib: 标准库/Bun 已有 · native: 平台已有(CSS/DB 约束)· yagni: 单实现的抽象/无人设的配置 · shrink: 同逻辑更少行。
格式:L<行>: <tag> <what>. <replacement>.
不要 flag(不是膨胀)
文档化的 ponytail:/DEFER、契约面、刻意留的扩展缝 = 规划非投机,别 yagni/delete;前端体验代码(动效/状态/层级)= 交付物非灵活性,别删。
转述纪律
每条删除建议给"删了它谁受损"的反证——确认无真实调用方 + 无近期演进信号才建议删。报告是候选,动手前自己核实引用面,别凭车队一句话砍代码。
与既有 skill 的边界
- omd-slim = 只找过度工程 + 记已知债,只删不加。找 bug/正确性 → /omd-review;扫安全 → /omd-audit;架构浅模块加厚(是"加"不是"删") → /omd-deepen。
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.
- 12d ago First seen · 35 lines · 94 tokens per session scan A d89e1d4cf6d7
omd-slim is a skill published in the GitHub repository AbyssCN/oh-my-dag (39 stars, last pushed yesterday), licensed MIT. It adds 94 tokens to every session and 838 once invoked, about $0.0005 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.

optimization
Use when improving performance, latency, throughput, memory usage, or general efficiency. Start by defining target metrics, measuring comprehensively, attributing bottlenecks, validating with static analysis, and prioritizing macro-optimizations before micro-optimizations.
smiles-validation
Strict SMILES validation, structural comparison, and modification verification. Catches invalid LLM-generated molecules.
neuron-debugger
Debug and monitor Neuron AI applications with Inspector APM, event observability, logging, and performance analysis. Use this skill whenever the user mentions debugging, monitoring, observability, performance analysis, tracing, Inspector, or needs to understand why an agent is behaving a certain way. Also trigger for…
code-search
Search a codebase efficiently with ripgrep regular expressions, file globs, and git history search. Use to locate symbols, usages, and definitions instead of reading whole files.
agent-identity
Verify an agent's live address and billing account before sharing a chat link, diagnosing a deploy mismatch, or deciding why two hosts share an identity.
data-fetching
Use when implementing or debugging ANY network request, API call, or data fetching. Covers fetch API, axios, React Query, SWR, error handling, caching strategies, offline support.
