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 | $0.00018 | $0.00403 |
| Opus 5 | $0.00009 | $0.00201 |
| Sonnet 5 | $0.00004 | $0.00081 |
| Haiku 4.5 | $0.00002 | $0.00040 |
Grade A, and why
implement-slice 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 3d 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
实现 Slice
实现一条聚焦的 vertical slice，并补齐 tests、验证和状态更新。
触发时机
以下情况使用这个 skill：
docs/plans/active.md已定义当前 slice。- 用户要求实现一个已经定框的功能。
- 下一步应该写代码，而不是继续规划。
必读材料
AGENTS.mddocs/product.mddocs/architecture.mddocs/plans/active.mdfeature_list.json- 相关源码文件。
- 相关 tests。
流程
- 简要复述当前 feature、slice 和验收标准。
- 编辑前先检查现有代码模式。
- 在实际可行时，先添加或更新行为 tests。
- 用最小改动满足 slice。
- 运行
./scripts/check.sh。 - 更新 feature evidence 后运行
./scripts/validate-feature-list.sh .。 - 当改动触及构建、集成、持久化或公开行为时，运行
./scripts/verify.sh。 - 更新
docs/status.md：改动、feature 状态、已运行命令、结果、风险、下一步。 - 如果出现重复失败，进入 mistake ratchet。
产出
- 聚焦当前 slice 的代码改动。
- Tests，或明确说明测试缺口。
- 验证证据。
- 更新后的 feature state。
- 更新后的 status。
- 建议的 commit message。
边界
- 没有新 plan，不要扩展任务。
- 不要同时推进多个 feature。
- 没有证据，不要声称命令已经运行。
- 不要静默忽略失败的检查。
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.

implement-slice is a skill published in the GitHub repository CadeYu/vibe-harness (5 stars, last pushed 2mo ago), licensed MIT. It adds 18 tokens to every session and 403 once invoked, about $0.0001 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 2026-08-31.
