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 | $0.00087 | $0.01980 |
| Opus 5.5 | $0.00035 | $0.00792 |
| Sonnet 5.5 | $0.00017 | $0.00396 |
| Haiku 4.5 | $0.00009 | $0.00198 |
Grade A, and why
devlab-web-context 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 1mo 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.

devlab-web-context — 前端项目上下文理解规则资产
<domain>-context家族(web/srv/infra/tool)首个成员。只提供 Understand Capability: 规定"什么时候理解、理解什么、理解到什么程度",产出前端 context 画像,不生产五件套台账。
定位与边界
- 本技能是什么:web 域前端项目上下文理解规则(信号表 + 特有条目 + 渐进式理解工作流)。
- 本技能不是什么:不生产
.harness/devlab/五件套台账(那是devlab-context-bootstrap的职责);不是工程化能力层(那是devlab-web-engineering);不自建 CLI(社区 CLI/MCP/Skill 引用策略见 bootstrap 通用层)。 - 家族化:与未来的
devlab-srv-context/devlab-infra-context/devlab-tool-context同构——共享 bootstrap 通用层(四原则全文 + 社区引用 + 五件套骨架),本技能只承载 web 领域规则。
四原则(一句话摘要)
完整原则全文在
devlab-context-bootstrap(缺失时本摘要可独立指导行为)。
- context-before-change:改动任何代码前先建立最小上下文,禁止在未知项目状态下动手。
- evidence-before-assumption:画像条目只写实证(读到的配置/跑通的命令);推断必须标注依据;未验证标
todo。 - progressive-understanding:按需加深,最小上下文起步,置信度不达标才 Deepen,不做一次性全量理解。
- re-understand:执行中发现认知偏差(命令跑不通/现象与画像不符)立即回退重理解,不将错就错。
双模式入口
模式 A:规则包模式(被 bootstrap 委托)
触发方:devlab-context-bootstrap Phase 0 判定 frontend-web 后。
执行:
- 判定前端子类型(信号文件):有
qiankun/micro-app/自研 shell 注册配置 →vue-microfrontend;有react+ SPA 结构 →react-spa;默认vue-microfrontend(当前实证最全)。 - 读取
profiles/<profile_type>.md(子类型特有信号与条目)+references/REFERENCE-WEB-RULES.md(跨子类型通用信号)。 - 按信号表扫描项目,逐条产出画像维度(key/value/confidence/evidence/note)。
- 画像写入
.harness/devlab/context/<project>-web-context.yaml(契约见下文)。 - 返回给 bootstrap:画像路径 + 概要(profile_type / overall_confidence / 主要发现)。
模式 B:完整工作流模式(独立自编排)
触发:用户直接要求"理解这个前端项目 / 生成前端 context 画像"。
工作流(四步循环):
Task
↓
Identify Scope # 项目根、子应用清单(monorepo 逐个)、理解目的(改代码/排障/验收)
↓
Build Minimal Context # 读 profiles/<type>.md + REFERENCE-WEB-RULES → 最小信号扫描
↓
Confidence Check # 每条目标 confidence:confirmed 需 evidence;不足 → Deepen
↓
足够理解 → 产出画像并结束
不足 → Deepen Context # 读更多配置/跑命令/查注册配置
认知偏差 → Re-understand # 回退重扫,更新画像
结束条件:所有关键键达到 confirmed 或 inferred(无未解释的 todo 阻塞),或资源上限(扫描轮次/时间)。
产出:前端 context 画像(契约见下)。需落台账时 → 委托 devlab-context-bootstrap(镜像衔接:bootstrap 消费画像填五件套)。
What ships with it
9 files 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.

devlab-web-context is a skill published in the GitHub repository seed-forge/harness-ai-kit (25 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 87 tokens to every session and 1,980 once invoked, about $0.0003 per session on Opus 5.5. 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.
