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 | $0.00102 | $0.01207 |
| Opus 5 | $0.00051 | $0.00603 |
| Sonnet 5 | $0.00020 | $0.00241 |
| Haiku 4.5 | $0.00010 | $0.00121 |
Grade A, and why
dev-flow-oneliner-be scanned grade A with 1 finding 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.
dev-flow-oneliner-be
适用场景
- "给 X 接口加个返回字段"、"列表加个按 status 过滤" 这类后端微需求
- 不涉及 DB 迁移
- 预估 4 小时内可完成（>8 工时强制升级
/dev-flow-doc-be）
前置条件
确认 _playbook.md Part B.3 启动参数；one_liner 必填。
流程步骤
本 skill 与
/dev-flow-oneliner-fe同构，但必出API_CONTRACT.md与IMPACT_ANALYSIS.md。
阶段 0 · 上下文初始化
move_agent_to_root 进项目；建知识库目录；META.md 极简版。
阶段 1 · 一句话补 PRD（含契约）
SwitchMode→ plan- 把一句话补成
MINI_PRD.md，必出API_CONTRACT.md（即使是字段微调，也写出最终签名） - 强制升级阈值：
- 涉及 DB 改动 → 强制升级
/dev-flow-doc-be（M4 加成） - 估算 >8 工时 → 强制升级
/dev-flow-doc-be
- 涉及 DB 改动 → 强制升级
阶段 2 · 卡点 1 + 契约交付
prompt: "迷你 PRD（MINI_PRD.md）+ API 契约（API_CONTRACT.md）已就绪，请确认："
options:
- "理解正确 + 契约已与前端 owner 对齐，进入实现"
- "需要修改（说明）"
- "实际比想的复杂，建议升级到 dev-flow-doc-be"
阶段 3 · 项目勘察（精简）
派 1 个 explore subagent：找出待修改文件 + 横切关注点（鉴权？事务？日志？）+ 一句话 IMPACT_ANALYSIS.md（哪些接口/任务可能被影响）。
阶段 4 · 方案设计（精简）
git checkout -b feature/[feature]IMPLEMENTATION_PLAN.md半页：影响文件 + 改动要点/plan-eng-review可跳过（小改动），但任何鉴权 / 数据可见性改动必须/cso
阶段 5 · 实现 + 自查
backend-agent或主线程/qa（接口层快速）+/review- 鉴权/可见性改动必做
/cso - 用 curl/Postman 跑一遍新行为
阶段 6 · 上线
/ship → /land-and-deploy → /canary（监控同类接口耗时和错误率）。
阶段 7 · 复盘（极简）
append _lessons.md 一行：场景 + 实际工时 + 是否触发升级阈值。
错误处理
- 估算超过 8 工时 / 涉及 DB → 强制升级
/dev-flow-doc-be - 实现中发现需要前端改动 → 升级
/dev-flow-oneliner-full - 影响范围超出预期 → 暂停，回阶段 3 重做
IMPACT_ANALYSIS.md
产物清单
META.md（极简）、MINI_PRD.md、API_CONTRACT.md（必出）、IMPACT_ANALYSIS.md（一句话）、IMPLEMENTATION_PLAN.md（半页）、PR 链接。
支持的修饰符
- M5 只联调 → 几乎不会出现在一句话场景；如出现立即升级
/dev-flow-doc-be

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.
- 5d ago First seen · 101 lines · 102 tokens per session scan A 1abb674017a9
dev-flow-oneliner-be is a skill published in the GitHub repository movebrickschi/harness-engineering-mcp (2 stars, last pushed 3mo ago), licensed MIT. It adds 102 tokens to every session and 1,207 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
