PROACTIVE

"false"

, do not proactively suggest gstack skills — only invoke them when the user explicitly asks. The user opted out of proactive suggestions.

If output shows

UPGRADE_AVAILABLE <old> <new>

: read

~/.claude/skills/gstack/gstack-upgrade/SKILL.md

and follow the "Inline upgrade flow" (auto-upgrade if configured, otherwise AskUserQuestion with 4 options, write snooze state if declined). If

JUST_UPGRADED <from> <to>

: tell user "Running gstack v{to} (just updated!)" and continue.

LAKE_INTRO

no

: Before continuing, introduce the Completeness Principle. Tell the user: "gstack follows the Boil the Lake principle — always do the complete thing when AI makes the marginal cost near-zero.

touch ~/.gstack/.completeness-intro-seen

Only run

open

if the user says yes. Always run

touch

to mark as seen. This only happens once.

TEL_PROMPTED

no

AND

LAKE_INTRO

yes

: After the lake intro is handled, ask the user about telemetry. Use AskUserQuestion:

Help gstack get better! Community mode shares usage data (which skills you use, how long they take, crash info) with a stable device ID so we can track trends and fix bugs faster. No code, file paths, or repo names are ever sent. Change anytime with
gstack-config set telemetry off
.

Options:

A) Help gstack get better! (recommended)
B) No thanks

If A: run

~/.claude/skills/gstack/bin/gstack-config set telemetry community

If B: ask a follow-up AskUserQuestion:

How about anonymous mode? We just learn that someone used gstack — no unique ID, no way to connect sessions. Just a counter that helps us know if anyone's out there.

Options:

A) Sure, anonymous is fine
B) No thanks, fully off

If B→A: run

~/.claude/skills/gstack/bin/gstack-config set telemetry anonymous

If B→B: run

如果

PROACTIVE

为

"false"

，请勿主动推荐gstack技能——仅在用户明确要求时调用。用户已选择退出主动推荐。

如果输出显示

UPGRADE_AVAILABLE <old> <new>

：请阅读

~/.claude/skills/gstack/gstack-upgrade/SKILL.md

并遵循“内联升级流程”（如果已配置则自动升级，否则向用户提供4个选项的问题，若用户拒绝则设置 snooze 状态）。如果显示

JUST_UPGRADED <from> <to>

：告知用户“正在运行gstack v{to}（刚刚完成更新！）”并继续。

如果

LAKE_INTRO

为

no

：在继续之前，先介绍完整性原则。告知用户：“gstack遵循‘煮沸湖泊’原则——当AI使得边际成本趋近于零时，始终完成完整的工作。了解更多：https://garryslist.org/posts/boil-the-ocean” 然后询问用户是否要在默认浏览器中打开该文章：

bash

open https://garryslist.org/posts/boil-the-ocean

仅在用户同意时运行

open

命令。无论如何都要运行

touch

命令标记为已查看。此操作仅执行一次。

如果

TEL_PROMPTED

为

no

且

LAKE_INTRO

为

yes

：在处理完湖泊原则介绍后，询问用户遥测相关事宜。使用AskUserQuestion：

帮助gstack变得更好！社区模式会共享使用数据（你使用的技能、耗时、崩溃信息）以及一个稳定的设备ID，以便我们更快地跟踪趋势和修复bug。绝不会发送代码、文件路径或仓库名称。可随时通过
gstack-config set telemetry off
更改设置。

选项：

A) 帮助gstack变得更好！（推荐）
B) 不用了，谢谢

如果选择A：运行

~/.claude/skills/gstack/bin/gstack-config set telemetry community

如果选择B：发起后续的AskUserQuestion：

那匿名模式呢？我们只会了解到有人使用了gstack——没有唯一ID，无法关联会话。只是一个计数器，帮助我们了解是否有用户在使用。

选项：

A) 好的，匿名模式可以接受
B) 不用了，完全关闭

如果B→A：运行

~/.claude/skills/gstack/bin/gstack-config set telemetry anonymous

如果B→B：运行

~/.claude/skills/gstack/bin/gstack-config set telemetry off

始终运行：

bash

，则完全跳过此步骤。

AskUserQuestion Format

AskUserQuestion格式

ALWAYS follow this structure for every AskUserQuestion call:

Re-ground: State the project, the current branch (use the
```
_BRANCH
```
value printed by the preamble — NOT any branch from conversation history or gitStatus), and the current plan/task. (1-2 sentences)
Simplify: Explain the problem in plain English a smart 16-year-old could follow. No raw function names, no internal jargon, no implementation details. Use concrete examples and analogies. Say what it DOES, not what it's called.
Recommend:
```
RECOMMENDATION: Choose [X] because [one-line reason]
```
— always prefer the complete option over shortcuts (see Completeness Principle). Include
```
Completeness: X/10
```
for each option. Calibration: 10 = complete implementation (all edge cases, full coverage), 7 = covers happy path but skips some edges, 3 = shortcut that defers significant work. If both options are 8+, pick the higher; if one is ≤5, flag it.
Options: Lettered options:
```
A) ... B) ... C) ...
```
— when an option involves effort, show both scales:
```
(human: ~X / CC: ~Y)
```

Assume the user hasn't looked at this window in 20 minutes and doesn't have the code open. If you'd need to read the source to understand your own explanation, it's too complex.

Per-skill instructions may add additional formatting rules on top of this baseline.

每次调用AskUserQuestion时必须遵循以下结构：

重新梳理背景： 说明项目、当前分支（使用前置步骤输出的
```
_BRANCH
```
值——不要使用对话历史或gitStatus中的任何分支）以及当前计划/任务。（1-2句话）
简化解释： 用16岁聪明人能理解的简单英语解释问题。不要使用原始函数名、内部行话或实现细节。使用具体示例和类比。说明它的功能，而不是它的名称。
推荐：
```
RECOMMENDATION: 选择[X]，因为[一句话理由]
```
——始终优先选择完整选项而非捷径（请参阅完整性原则）。为每个选项包含
```
Completeness: X/10
```
。评分标准：10 = 完整实现（覆盖所有边缘案例、全面覆盖），7 = 覆盖常规路径但忽略部分边缘案例，3 = 推迟大量工作的捷径。如果两个选项均为8+，选择评分更高的；如果其中一个≤5，标记出来。
选项： 带字母的选项：
```
A) ... B) ... C) ...
```
——当某个选项涉及工作量时，同时显示两种估算：
```
(人工: ~X / CC: ~Y)
```

假设用户已有20分钟未查看此窗口且未打开代码。如果需要阅读源代码才能理解你的解释，说明解释过于复杂。

特定技能的说明可能会在此基线规则之上添加额外的格式要求。

Completeness Principle — Boil the Lake

完整性原则——煮沸湖泊

AI-assisted coding makes the marginal cost of completeness near-zero. When you present options:

If Option A is the complete implementation (full parity, all edge cases, 100% coverage) and Option B is a shortcut that saves modest effort — always recommend A. The delta between 80 lines and 150 lines is meaningless with CC+gstack. "Good enough" is the wrong instinct when "complete" costs minutes more.
Lake vs. ocean: A "lake" is boilable — 100% test coverage for a module, full feature implementation, handling all edge cases, complete error paths. An "ocean" is not — rewriting an entire system from scratch, adding features to dependencies you don't control, multi-quarter platform migrations. Recommend boiling lakes. Flag oceans as out of scope.
When estimating effort, always show both scales: human team time and CC+gstack time. The compression ratio varies by task type — use this reference:

Task type	Human team	CC+gstack	Compression
Boilerplate / scaffolding	2 days	15 min	~100x
Test writing	1 day	15 min	~50x
Feature implementation	1 week	30 min	~30x
Bug fix + regression test	4 hours	15 min	~20x
Architecture / design	2 days	4 hours	~5x
Research / exploration	1 day	3 hours	~3x

This principle applies to test coverage, error handling, documentation, edge cases, and feature completeness. Don't skip the last 10% to "save time" — with AI, that 10% costs seconds.

Anti-patterns — DON'T do this:

BAD: "Choose B — it covers 90% of the value with less code." (If A is only 70 lines more, choose A.)
BAD: "We can skip edge case handling to save time." (Edge case handling costs minutes with CC.)
BAD: "Let's defer test coverage to a follow-up PR." (Tests are the cheapest lake to boil.)
BAD: Quoting only human-team effort: "This would take 2 weeks." (Say: "2 weeks human / ~1 hour CC.")

AI辅助编码使得完整性的边际成本趋近于零。当你提供选项时：

如果选项A是完整实现（完全对等、覆盖所有边缘案例、100%覆盖），而选项B是节省少量工作量的捷径——始终推荐A。在CC+gstack的帮助下，80行代码和150行代码之间的差异毫无意义。当“完整”只需多花几分钟时，“足够好”是错误的直觉。
湖泊与海洋： “湖泊”是可以煮沸的——模块的100%测试覆盖率、完整的功能实现、处理所有边缘案例、完整的错误路径。“海洋”则不行——从头重写整个系统、向你无法控制的依赖项添加功能、耗时多个季度的平台迁移。建议煮沸湖泊。标记海洋为超出范围。
估算工作量时，始终同时显示两种尺度：人工团队时间和CC+gstack时间。压缩比因任务类型而异——请参考以下标准：

任务类型	人工团队	CC+gstack	压缩比
样板代码/脚手架	2天	15分钟	~100倍
测试编写	1天	15分钟	~50倍
功能实现	1周	30分钟	~30倍
错误修复+回归测试	4小时	15分钟	~20倍
架构/设计	2天	4小时	~5倍
研究/探索	1天	3小时	~3倍

此原则适用于测试覆盖率、错误处理、文档、边缘案例和功能完整性。不要为了“节省时间”而跳过最后10%——借助AI，这10%只需几秒钟。

反模式——请勿这样做：

错误：“选择B——它用更少的代码覆盖了90%的价值。”（如果A只多70行代码，选择A。）
错误：“我们可以跳过边缘案例处理以节省时间。”（借助CC，边缘案例处理只需几分钟。）
错误：“我们将测试覆盖率推迟到后续PR中。”（测试是最容易煮沸的湖泊。）
错误：仅引用人工团队工作量：“这需要2周时间。”（应该说：“人工团队2周 / CC约1小时。”）

Search Before Building

先搜索再构建

Before building infrastructure, unfamiliar patterns, or anything the runtime might have a built-in — search first. Read

~/.claude/skills/gstack/ETHOS.md

for the full philosophy.

Three layers of knowledge:

Layer 1 (tried and true — in distribution). Don't reinvent the wheel. But the cost of checking is near-zero, and once in a while, questioning the tried-and-true is where brilliance occurs.
Layer 2 (new and popular — search for these). But scrutinize: humans are subject to mania. Search results are inputs to your thinking, not answers.
Layer 3 (first principles — prize these above all). Original observations derived from reasoning about the specific problem. The most valuable of all.

Eureka moment: When first-principles reasoning reveals conventional wisdom is wrong, name it: "EUREKA: Everyone does X because [assumption]. But [evidence] shows this is wrong. Y is better because [reasoning]."

Log eureka moments:

bash

jq -n --arg ts "$(date -u +%Y-%m-%dT%H:%M:%SZ)" --arg skill "SKILL_NAME" --arg branch "$(git branch --show-current 2>/dev/null)" --arg insight "ONE_LINE_SUMMARY" '{ts:$ts,skill:$skill,branch:$branch,insight:$insight}' >> ~/.gstack/analytics/eureka.jsonl 2>/dev/null || true

Replace SKILL_NAME and ONE_LINE_SUMMARY. Runs inline — don't stop the workflow.

WebSearch fallback: If WebSearch is unavailable, skip the search step and note: "Search unavailable — proceeding with in-distribution knowledge only."

在构建基础设施、不熟悉的模式或运行时可能内置的任何功能之前——先搜索。阅读

~/.claude/skills/gstack/ETHOS.md

了解完整理念。

三层知识：

第一层（久经考验——已内置）。不要重复造轮子。但检查的成本几乎为零，偶尔质疑久经考验的做法可能会带来创新。
第二层（新颖且流行——搜索这些）。但要仔细审查：人类容易陷入狂热。搜索结果是思考的输入，而非答案。
第三层（第一性原理——最有价值）。从对特定问题的推理中得出的原创观察。是所有知识中最有价值的。

灵光一现时刻： 当第一性原理推理揭示传统智慧是错误的时，将其命名： “EUREKA：每个人都做X是因为[假设]。但[证据]表明这是错误的。Y更好，因为[推理]。”

记录灵光一现时刻：

bash

jq -n --arg ts "$(date -u +%Y-%m-%dT%H:%M:%SZ)" --arg skill "SKILL_NAME" --arg branch "$(git branch --show-current 2>/dev/null)" --arg insight "ONE_LINE_SUMMARY" '{ts:$ts,skill:$skill,branch:$branch,insight:$insight}' >> ~/.gstack/analytics/eureka.jsonl 2>/dev/null || true

替换SKILL_NAME和ONE_LINE_SUMMARY。内联运行——不要中断工作流。

WebSearch回退： 如果WebSearch不可用，跳过搜索步骤并注明：“搜索不可用——仅使用内置知识继续。”

Contributor Mode

贡献者模式

_CONTRIB

true

: you are in contributor mode. You're a gstack user who also helps make it better.

At the end of each major workflow step (not after every single command), reflect on the gstack tooling you used. Rate your experience 0 to 10. If it wasn't a 10, think about why. If there is an obvious, actionable bug OR an insightful, interesting thing that could have been done better by gstack code or skill markdown — file a field report. Maybe our contributor will help make us better!

Calibration — this is the bar: For example,

$B js "await fetch(...)"

used to fail with

SyntaxError: await is only valid in async functions

because gstack didn't wrap expressions in async context. Small, but the input was reasonable and gstack should have handled it — that's the kind of thing worth filing. Things less consequential than this, ignore.

NOT worth filing: user's app bugs, network errors to user's URL, auth failures on user's site, user's own JS logic bugs.

To file: write

~/.gstack/contributor-logs/{slug}.md

with all sections below (do not truncate — include every section through the Date/Version footer):

undefined

如果

_CONTRIB

为

true

：你处于贡献者模式。你是gstack用户，同时也帮助改进它。

在每个主要工作流步骤结束时（不是每个命令之后），反思你使用的gstack工具。对你的体验进行0到10的评分。如果评分不是10，思考原因。如果存在明显的、可操作的bug，或者gstack代码或技能markdown本可以做得更好的、有洞察力的有趣点——提交现场报告。也许我们的贡献者会帮助我们变得更好！

评分标准——参考案例： 例如，

$B js "await fetch(...)"

曾经因

SyntaxError: await is only valid in async functions

失败，因为gstack没有将表达式包装在异步上下文中。这是一个小问题，但输入是合理的，gstack本应处理它——这种情况值得提交。比这更无关紧要的问题可以忽略。

不值得提交的情况： 用户应用程序的bug、用户URL的网络错误、用户站点的认证失败、用户自己的JS逻辑bug。

提交报告： 编写

~/.gstack/contributor-logs/{slug}.md

，包含以下所有部分（不要截断——包括到日期/版本页脚的每个部分）：

undefined

{Title}

{标题}

Hey gstack team — ran into this while using /{skill-name}:

What would make this a 10

如何达到10分

{one sentence: what gstack should have done differently}

Date: {YYYY-MM-DD} | Version: {gstack version} | Skill: /{skill}


Slug: lowercase, hyphens, max 60 chars (e.g. `browse-js-no-await`). Skip if file already exists. Max 3 reports per session. File inline and continue — don't stop the workflow. Tell user: "Filed gstack field report: {title}"

{一句话：gstack本应如何改进}

日期： {YYYY-MM-DD} | 版本： {gstack版本} | 技能： /{skill}


Slug：小写、连字符分隔、最多60个字符（例如`browse-js-no-await`）。如果文件已存在则跳过。每个会话最多提交3份报告。内联编写并继续——不要中断工作流。告知用户：“已提交gstack现场报告：{标题}”

Completion Status Protocol

完成状态协议

When completing a skill workflow, report status using one of:

DONE — All steps completed successfully. Evidence provided for each claim.
DONE_WITH_CONCERNS — Completed, but with issues the user should know about. List each concern.
BLOCKED — Cannot proceed. State what is blocking and what was tried.
NEEDS_CONTEXT — Missing information required to continue. State exactly what you need.

完成技能工作流时，使用以下之一报告状态：

DONE — 所有步骤成功完成。为每个声明提供证据。
DONE_WITH_CONCERNS — 已完成，但存在用户应了解的问题。列出每个问题。
BLOCKED — 无法继续。说明阻塞因素和已尝试的解决方法。
NEEDS_CONTEXT — 缺少继续所需的信息。明确说明需要什么。

Escalation

升级处理

It is always OK to stop and say "this is too hard for me" or "I'm not confident in this result."

Bad work is worse than no work. You will not be penalized for escalating.

If you have attempted a task 3 times without success, STOP and escalate.
If you are uncertain about a security-sensitive change, STOP and escalate.
If the scope of work exceeds what you can verify, STOP and escalate.

Escalation format:

STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2 sentences]
ATTEMPTED: [what you tried]
RECOMMENDATION: [what the user should do next]

随时可以停止并说“这对我来说太难了”或“我对结果没有信心”。

糟糕的工作比没有工作更糟。你不会因升级处理而受到惩罚。

如果你尝试某项任务3次均未成功，停止并升级处理。
如果你对安全敏感的更改不确定，停止并升级处理。
如果工作范围超出你可以验证的范围，停止并升级处理。

升级处理格式：

STATUS: BLOCKED | NEEDS_CONTEXT
REASON: [1-2句话]
ATTEMPTED: [你尝试的操作]
RECOMMENDATION: [用户接下来应采取的措施]

Telemetry (run last)

遥测（最后运行）

After the skill workflow completes (success, error, or abort), log the telemetry event. Determine the skill name from the

name:

field in this file's YAML frontmatter. Determine the outcome from the workflow result (success if completed normally, error if it failed, abort if the user interrupted).

PLAN MODE EXCEPTION — ALWAYS RUN: This command writes telemetry to

~/.gstack/analytics/

(user config directory, not project files). The skill preamble already writes to the same directory — this is the same pattern. Skipping this command loses session duration and outcome data.

Run this bash:

bash

_TEL_END=$(date +%s)
_TEL_DUR=$(( _TEL_END - _TEL_START ))
rm -f ~/.gstack/analytics/.pending-"$_SESSION_ID" 2>/dev/null || true
~/.claude/skills/gstack/bin/gstack-telemetry-log \
  --skill "SKILL_NAME" --duration "$_TEL_DUR" --outcome "OUTCOME" \
  --used-browse "USED_BROWSE" --session-id "$_SESSION_ID" 2>/dev/null &

Replace

SKILL_NAME

with the actual skill name from frontmatter,

OUTCOME

with success/error/abort, and

USED_BROWSE

with true/false based on whether

$B

was used. If you cannot determine the outcome, use "unknown". This runs in the background and never blocks the user.

技能工作流完成后（成功、错误或中止），记录遥测事件。从此文件YAML前置内容的

name:

字段中确定技能名称。根据工作流结果确定结果（正常完成则为success，失败则为error，用户中断则为abort）。

计划模式例外——始终运行： 此命令将遥测数据写入

~/.gstack/analytics/

（用户配置目录，而非项目文件）。技能前置步骤已写入同一目录——这是相同的模式。跳过此命令会丢失会话时长和结果数据。

运行以下bash命令：

bash

_TEL_END=$(date +%s)
_TEL_DUR=$(( _TEL_END - _TEL_START ))
rm -f ~/.gstack/analytics/.pending-"$_SESSION_ID" 2>/dev/null || true
~/.claude/skills/gstack/bin/gstack-telemetry-log \
  --skill "SKILL_NAME" --duration "$_TEL_DUR" --outcome "OUTCOME" \
  --used-browse "USED_BROWSE" --session-id "$_SESSION_ID" 2>/dev/null &

将

SKILL_NAME

替换为前置内容中的实际技能名称，

OUTCOME

替换为success/error/abort，

USED_BROWSE

根据是否使用

$B

替换为true/false。如果无法确定结果，使用“unknown”。此命令在后台运行，绝不会阻塞用户。

SETUP (run this check BEFORE any browse command)

设置（在任何browse命令之前运行此检查）

bash

_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)
B=""
[ -n "$_ROOT" ] && [ -x "$_ROOT/.claude/skills/gstack/browse/dist/browse" ] && B="$_ROOT/.claude/skills/gstack/browse/dist/browse"
[ -z "$B" ] && B=~/.claude/skills/gstack/browse/dist/browse
if [ -x "$B" ]; then
  echo "READY: $B"
else
  echo "NEEDS_SETUP"
fi

NEEDS_SETUP

Tell the user: "gstack browse needs a one-time build (~10 seconds). OK to proceed?" Then STOP and wait.
Run:
```
cd <SKILL_DIR> && ./setup
```

bun

is not installed:

curl -fsSL https://bun.sh/install | bash

bash

_ROOT=$(git rev-parse --show-toplevel 2>/dev/null)

[ -z "$B" ] && B=~/.claude/skills/gstack/browse/dist/browse
if [ -x "$B" ]; then
  echo "READY: $B"
else
  echo "NEEDS_SETUP"
fi

如果显示

NEEDS_SETUP

：

告知用户：“gstack browse需要一次性构建（约10秒）。是否可以继续？”然后停止并等待。
运行：
```
cd <SKILL_DIR> && ./setup
```

Instructions

说明

Phase 1: Setup

阶段1：设置

bash

eval $(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null || echo "SLUG=unknown")
mkdir -p .gstack/benchmark-reports
mkdir -p .gstack/benchmark-reports/baselines

bash

eval $(~/.claude/skills/gstack/bin/gstack-slug 2>/dev/null || echo "SLUG=unknown")
mkdir -p .gstack/benchmark-reports
mkdir -p .gstack/benchmark-reports/baselines

Phase 2: Page Discovery

阶段2：页面发现

Same as /canary — auto-discover from navigation or use

--pages

--diff

mode:

bash

git diff $(gh pr view --json baseRefName -q .baseRefName 2>/dev/null || gh repo view --json defaultBranchRef -q .defaultBranchRef.name 2>/dev/null || echo main)...HEAD --name-only

与/canary相同——从导航自动发现或使用

--pages

指定。

如果是

--diff

模式：

bash

git diff $(gh pr view --json baseRefName -q .baseRefName 2>/dev/null || gh repo view --json defaultBranchRef -q .defaultBranchRef.name 2>/dev/null || echo main)...HEAD --name-only

Phase 3: Performance Data Collection

阶段3：性能数据收集

For each page, collect comprehensive performance metrics:

bash

$B goto <page-url>
$B perf

Then gather detailed metrics via JavaScript:

bash

$B eval "JSON.stringify(performance.getEntriesByType('navigation')[0])"

Extract key metrics:

TTFB (Time to First Byte):
```
responseStart - requestStart
```
FCP (First Contentful Paint): from PerformanceObserver or
```
paint
```
entries
LCP (Largest Contentful Paint): from PerformanceObserver
DOM Interactive:
```
domInteractive - navigationStart
```
DOM Complete:
```
domComplete - navigationStart
```
Full Load:
```
loadEventEnd - navigationStart
```

Resource analysis:

bash

$B eval "JSON.stringify(performance.getEntriesByType('resource').map(r => ({name: r.name.split('/').pop().split('?')[0], type: r.initiatorType, size: r.transferSize, duration: Math.round(r.duration)})).sort((a,b) => b.duration - a.duration).slice(0,15))"

Bundle size check:

bash

$B eval "JSON.stringify(performance.getEntriesByType('resource').filter(r => r.initiatorType === 'script').map(r => ({name: r.name.split('/').pop().split('?')[0], size: r.transferSize})))"
$B eval "JSON.stringify(performance.getEntriesByType('resource').filter(r => r.initiatorType === 'css').map(r => ({name: r.name.split('/').pop().split('?')[0], size: r.transferSize})))"

Network summary:

bash

$B eval "(() => { const r = performance.getEntriesByType('resource'); return JSON.stringify({total_requests: r.length, total_transfer: r.reduce((s,e) => s + (e.transferSize||0), 0), by_type: Object.entries(r.reduce((a,e) => { a[e.initiatorType] = (a[e.initiatorType]||0) + 1; return a; }, {})).sort((a,b) => b[1]-a[1])})})()"

为每个页面收集全面的性能指标：

bash

$B goto <page-url>
$B perf

然后通过JavaScript收集详细指标：

bash

$B eval "JSON.stringify(performance.getEntriesByType('navigation')[0])"

提取关键指标：

TTFB（首字节时间）：
```
responseStart - requestStart
```
FCP（首次内容绘制）：来自PerformanceObserver或
```
paint
```
条目
LCP（最大内容绘制）：来自PerformanceObserver
DOM Interactive（DOM交互就绪）：
```
domInteractive - navigationStart
```
DOM Complete（DOM加载完成）：
```
domComplete - navigationStart
```
Full Load（完全加载）：
```
loadEventEnd - navigationStart
```

资源分析：

bash

$B eval "JSON.stringify(performance.getEntriesByType('resource').map(r => ({name: r.name.split('/').pop().split('?')[0], type: r.initiatorType, size: r.transferSize, duration: Math.round(r.duration)})).sort((a,b) => b.duration - a.duration).slice(0,15))"

包大小检查：

bash

$B eval "JSON.stringify(performance.getEntriesByType('resource').filter(r => r.initiatorType === 'script').map(r => ({name: r.name.split('/').pop().split('?')[0], size: r.transferSize})))"
$B eval "JSON.stringify(performance.getEntriesByType('resource').filter(r => r.initiatorType === 'css').map(r => ({name: r.name.split('/').pop().split('?')[0], size: r.transferSize})))"

网络摘要：

bash

$B eval "(() => { const r = performance.getEntriesByType('resource'); return JSON.stringify({total_requests: r.length, total_transfer: r.reduce((s,e) => s + (e.transferSize||0), 0), by_type: Object.entries(r.reduce((a,e) => { a[e.initiatorType] = (a[e.initiatorType]||0) + 1; return a; }, {})).sort((a,b) => b[1]-a[1])})})()"

Phase 4: Baseline Capture (--baseline mode)

阶段4：基线捕获（--baseline模式）

Save metrics to baseline file:

json

  "url": "<url>",
  "timestamp": "<ISO>",
  "branch": "<branch>",
  "pages": {
    "/": {
      "ttfb_ms": 120,

      ]
    }
  }
}

写入到

Important Rules

重要规则

Measure, don't guess. Use actual performance.getEntries() data, not estimates.
Baseline is essential. Without a baseline, you can report absolute numbers but can't detect regressions. Always encourage baseline capture.
Relative thresholds, not absolute. 2000ms load time is fine for a complex dashboard, terrible for a landing page. Compare against YOUR baseline.
Third-party scripts are context. Flag them, but the user can't fix Google Analytics being slow. Focus recommendations on first-party resources.
Bundle size is the leading indicator. Load time varies with network. Bundle size is deterministic. Track it religiously.
Read-only. Produce the report. Don't modify code unless explicitly asked.

测量，而非猜测。 使用实际的performance.getEntries()数据，而非估算值。
基线至关重要。 没有基线，你可以报告绝对数值，但无法检测回归。始终鼓励捕获基线。
相对阈值，而非绝对阈值。 2000ms的加载时间对于复杂仪表板来说可以接受，但对于着陆页来说则很糟糕。与你自己的基线对比。
第三方脚本是上下文。 标记它们，但用户无法修复Google Analytics的缓慢问题。将推荐重点放在第一方资源上。
包大小是领先指标。 加载时间随网络变化。包大小是确定性的。要严格跟踪。
只读。 生成报告。除非明确要求，否则不要修改代码。
