+
+```sh
+go run ./examples/browser
+go run ./examples/passive
+go run ./examples/crawl
+```
+
+对应入口分别是 [browser](../../examples/browser/main.go)、[passive](../../examples/passive/main.go)、[crawl](../../examples/crawl/main.go)。每个入口只导入所需扩展；passive 不依赖 scanner 或浏览器，Katana 不依赖 scanner 或 Playwright。实际浏览器操作仍需要本机 Chrome，测绘查询按来源要求配置凭证。
+
+`exts/scanner.Config.Crawler` 接受 `scan.Crawler`；组合根传入 `katana.Crawl` 后，quick 扫描增加普通爬取，full 扫描增加浏览器爬取。未注入 crawler 时，scan 只运行自身能力。scan 保留目标过滤、去重和流水线事件，Katana 适配器负责网络与浏览器生命周期。
+
+passive 的配置声明位于 `exts/passive/config`，运行扩展位于 `exts/passive`。宿主可以声明并保存配置而不链接运行实现；`recon` section、环境变量和现有 CLI flag 名称保持兼容，是否显示 flag 由宿主决定。
+

+各发行版的构建入口、产物和依赖见 [README 构建说明](../README_CN.md#构建源码发行版)，最小可运行代码见[自定义最小应用](../README_CN.md#自定义最小应用)。可选能力通过入口 imports 组装，独立 browser、passive、crawl 示例见[扩展开发](developer/extensions.md#按导入组合可选能力)。aiscan 的 `full` 选择完整发行版，构建标签由 [editions.env](../editions.env) 管理，实际步骤见 [Makefile](../Makefile)；原生录屏另见 [record](record.md)。
 
 自定义应用应明确分发哪些模型配置、知识文件和外部运行依赖。二进制中注册了浏览器或外部命令入口，并不意味着目标机器已经安装对应程序。固定源码版本后验证实际部署平台上的启动、一个完整任务和关闭；按 AGPL-3.0 的要求处理分发与源代码提供。

Declare every argument property and its meaning in parameters_schema; runtime extraction must distinguish user constraints from fresh allocation names. Never use example literals as fallback defaults, even when example args are supplied. Check ALL required ordinary arguments together before any external work; one parameters return must describe every missing field because the host extracts arguments only once. Do not write natural-language regexes to infer intent; JEV chooses semantic alternatives, and the main model supplies open args only when needed. Include ALL actual executable choices, never a fixed target list. Tool names and actual documented protocol syntax/sentinels may be literals. Deterministic protocol values need no semantic vote. Never copy sample values into executable source. The arguments example must cover all externally supplied task values used in the trace and all parameter guards; it must actually run the example rather than request parameters again.
 Requested subjects, selectors, field names and output destinations are also current arguments. Generalize the capability across those values rather than hardcoding the example's topic. Return actual evidence for the main model to compose its explanation; do not embed the sample answer. quote(value) quotes ONE shell argument. program("readerId",[JSON arguments]) serializes a named reader, defined as an independent function string in readers. Readers execute only through ordinary native tools; no captured host locals. Reader-returned candidates are DATA, not automatically dispatched. bind/choices/quote are available in serialized readers. Do not invent undocumented native names or result formats. Useful partial capabilities are valid if their boundaries and handoff are honest. Correct the complete function when previous/diagnostic are supplied.`

+type: Tool Playbook
+title: katana
+description: Use katana for deep web crawling with full parameter discovery. Produces URLs with query strings, form targets, and JS endpoints that spray crawl strips.
+tags: [easm, web, crawling]
+status: stable
+generated: { by: process:okf-maintain, at: 2026-08-02T11:46:25Z }
+---
+
+# Katana — Parameter-Aware Web Crawler
+
+Katana is a web crawler from ProjectDiscovery that preserves full URLs including query parameters, form actions, and JavaScript-discovered endpoints. Use it when you need to enumerate the attack surface of a web application beyond path discovery.
+
+## When to Use
+
+- After `scan` or `spray` discovers web targets — katana fills in the parameter layer that spray crawl strips
+- Before fuzzing — katana provides the target URLs with parameters to test
+- When JavaScript-heavy applications need deeper endpoint extraction (`-jc` flag)
+- When visible attack surface is thin — use katana as the batch candidate generator instead of manually extracting JS URLs one by one
+
+## Relationship to Spray Crawl
+
+Spray crawl discovers paths and fingerprints. Katana discovers parameterized URLs. They complement each other:
+
+- `spray --crawl` → paths, fingerprints, tech stack → feeds into neutron POC
+- `katana` → full URLs with `?key=value`, form targets, API endpoints → feeds into manual fuzzing
+
+Do not feed every discovered URL back to the model one by one. Save or consume katana output as a batch, group by host/path/parameter shape, then select high-value candidates for authorization, unauthenticated access, upload, GraphQL, or injection validation.
+
+## Common Usage
+
+```bash
+katana -u https://target.example -d 3 -jc
+katana -u https://target.example -d 2 -jsonl
+katana -u https://target.example -f qurl
+katana -u https://target.example -d 3 -jc -jsonl
+katana -list urls.txt -d 2 -jc -timeout 60
+
+# Rendered browser crawling
+katana -u https://target.example -hl -d 2 -jsonl
+katana -u https://target.example -hh -d 2 -jsonl
+katana -u https://target.example -hl --chrome-ws-url ws://127.0.0.1:9222/devtools/browser/<id>
+```
+
+## Browser Modes and Reuse
+
+- Standard Katana crawling does not launch a browser. `-jc` parses JavaScript responses but does not render the application.
+- `-hl` runs pure headless crawling and captures browser requests, dynamic navigation, forms, and rendered interactions.
+- `-hh` combines HTTP crawling with browser rendering. Prefer `-hl` when browser network events and SPA navigation must be emitted as results.
+- The full scan profile's `katana_deep` capability uses pure headless crawling; `katana_crawl` remains the lower-cost standard crawler.
+
+Cyber resolves a browser in this order:
+
+1. Katana `--chrome-ws-url` (`-cwu`) for an explicitly managed running process.
+2. Katana `--system-chrome-path` (`-scp`) for an explicitly selected executable.
+3. `CYBER_BROWSER_PATH` shared by Cyber Playwright, nuclei headless replay, and Katana.
+4. Installed Chrome, Chromium, or Edge in PATH or the standard OS install locations.
+5. Rod's existing browser cache, with its first-use download only when the cache is absent.
+
+Automatic reuse means the executable is shared while each engine starts an isolated process/profile. Cyber does not automatically attach to a user's running browser. Use `--chrome-ws-url` only when process-level reuse is intentional.
+
+## Useful Filters
+
+- `-f qurl` — only output URLs that contain query parameters
+- `-f kv` — output key=value pairs extracted from URLs
+- `-f path` — output only paths
+- `-em php,asp,jsp` — match specific extensions
+- `-ef css,js,png,jpg,gif,svg,woff` — filter out static assets
+
+## Output
+
+Default output is one URL per line. Use `-jsonl` for structured JSON with request/response details. Agent should pick the format that fits the task — plain URLs for quick review, JSON for parameter extraction.
+
+## Related concepts
+
+- Run Katana after the [scan pipeline](cyber://skills/cyber/okf/easm/scan.md), [spray](cyber://skills/cyber/okf/easm/spray.md), or
+  [passive discovery](cyber://skills/passive/passive.md) identifies web targets.
+- Katana complements Spray by preserving parameters; use
+  [playwright](cyber://skills/runtime/playwright.md) when discovered routes require JavaScript or
+  interactive validation.

+# Passive
+
+`passive` is an cyber command backed by `uncover` for cyberspace search. Pick a source with `-s`.
+

+
+Sources without credentials are silently skipped at init.
+Additional sources can be configured via `~/.uncover-config/provider-config.yaml`.
+
+## When to Use
+
+- **Domain/ICP → IPs, URLs, ports**: use a cyberspace source (`fofa`, `hunter`, `shodan`, etc.)
+- Feed output into `gogo`, `spray`, `katana`, or `neutron` for active scanning.
+
+Skip `passive` when the user already provided concrete IPs or private ranges.
+
+## Usage
+
+```bash
+passive -s fofa 'domain="example.com"'
+passive -s fofa 'icp="浙ICP备16020926号"'
+passive -s hunter 'domain.suffix="example.com"'
+passive -s shodan 'org:"Example"'
+```
+
+The positional argument is the source-native query string.
+
+## Output
+
+### FOFA
+
+JSON array with rich fields:
+
+```json
+[{"ip":"192.0.2.4","port":"443","url":"https://example.com","domain":"example.com","title":"Example","icp":"..."}]
+```
+
+### Hunter
+
+JSON array with extra fields: `status`, `company`, `frame`:
+
+```json
+[{"ip":"192.0.2.4","port":"443","url":"https://example.com","domain":"example.com","status":"200","company":"Example Inc","frame":"nginx","title":"Example","icp":"..."}]
+```
+
+### Other sources (shodan, censys, etc.)
+
+Generic JSON array:
+
+```json
+[{"ip":"192.0.2.4","port":"80","url":"http://example.com","host":"example.com","source":"shodan"}]
+```
+
+## Typical Pipeline
+
+1. `passive -s fofa 'icp="京ICP备xxx号"'` → get IPs/URLs
+2. `gogo` / `spray` / `katana` → active scan discovered assets
+
+## Notes
+
+- Hunter blocks overseas IPs; use `recon.proxy=socks5://...` for Hunter from abroad.
+- ICP data may lag reality; treat domain mapping as leads, not authoritative.
+
+## Related concepts
+
+- Passive discovery supplies targets to the [scan pipeline](cyber://skills/cyber/okf/easm/scan.md),
+  [gogo](cyber://skills/cyber/okf/easm/gogo.md), [spray](cyber://skills/cyber/okf/easm/spray.md), and [katana](cyber://skills/katana/katana.md).
+- Use the [proxy runtime](cyber://skills/runtime/proxy.md) when a configured discovery source
+  requires routed access.
