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 | $0.00079 | $0.00504 |
| Opus 5 | $0.00039 | $0.00252 |
| Sonnet 5 | $0.00016 | $0.00101 |
| Haiku 4.5 | $0.00008 | $0.00050 |
Grade A, and why
lite 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 2d 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
lite
和 build 同一套裁决纪律，只是没有前置文档：契约就是"这一个改动本身"。
判定与提醒
不动产品定义（不改 PD / TD / AC 语义）的改动走 lite。若发现改动实际会改变产品语义、
领域边界或长期技术约束，提醒一次并给出理由，建议走 design → build；
用户确认后仍可继续 lite，不强制拦截——但收尾时如实标注该风险。
永远不按预计工时判定。
做法（TDD 验收）
- 先为目标行为写出会失败的测试（bug 修复先复现失败），确认 RED 再实现。
- 行为已被既有 AC 覆盖时直接复用已锁的 Case，不新写第二份口径； 纯文案 / 静态样式 / 文档 / 注释等无运行时语义的改动，用对应的静态或 轻量真实入口 before/after 检查，不跑整条旅程。
- 转绿后跑受影响范围的回归（棘轮：已绿的不许变红）；触碰主链路时补跑 Core-Case。
- 收尾交付：diff、命令与退出码、before/after 证据；止步于哪一级验证，直说。
边界
- 不产生任何 feature 工件（brief / definition / 计划 / 报告），不派子代理。
- 不许悄悄修改已定案的 Oracle——需要改就是在动产品定义，回
design。 - 破坏性 / 生产 / 权限 / 不可逆操作仍需人类显式批准。
产出
已验收的改动 + 简洁证据。
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.

lite is a skill published in the GitHub repository wallkop/opc-develop (11 stars, last pushed 1mo ago), licensed MIT. It adds 79 tokens to every session and 504 once invoked, about $0.0004 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.
