http-fetch

http-fetch executes a single HTTP request (GET, POST, PUT, or DELETE) and returns the response body as text without spawning an LLM agent. Use it for lightweight data-fetch steps in meta-skill DAGs where a simple HTTP call is the only operation needed; for multi-page crawling, JavaScript rendering, complex authentication, or custom headers, delegate to a sub-agent with specialized tools instead.

# http-fetch (sub-skill)

Direct shell wrapper for a single HTTP request. Replaces
``sub-agent`` sub-Agent steps that just GET/POST a URL — order-of-
magnitude faster (no LLM round-trip, no tool surface, no iteration
loop).

## Inputs (``with:``)

| key         | required | default                | notes                                                          |
|-------------|----------|------------------------|----------------------------------------------------------------|
| `url`       | yes      | —                      | absolute http(s) URL                                           |
| `method`    | no       | `GET`                  | `GET` / `POST` / `PUT` / `DELETE` (case-insensitive)           |
| `body`      | no       | `''`                   | request body, piped via stdin (for POST/PUT); empty = no body  |
| `timeout`   | no       | `30`                   | request timeout in seconds                                     |
| `max_bytes` | no       | `2000000`              | response body cap; larger payloads truncated + suffixed `…`    |

## Output

- Success: response body on stdout (UTF-8 decoded, truncated to
  ``max_bytes`` if larger; lossy decode replaces invalid bytes).
- Non-2xx response: exit 1, stderr ``HTTP <code>: <reason> <body[:200]>``;
  stdout still carries the body for callers that want to inspect.
- Network / DNS / timeout failure: exit 2, stderr cause.

## When NOT to use

- Crawling multiple pages → use ``scrapling`` (via ``sub-agent``).
- JS-rendered pages → use ``sub-agent`` + browser tools.
- OAuth dance / multi-step auth → use ``sub-agent``.
- Streaming responses → not supported (we buffer + return).

## Fallback

If this skill is unavailable, callers should spawn ``sub-agent``
with a curl/requests task — same result, ~10× the latency and a
non-deterministic tool loop.
advanced-dubbing-studioSkill

Submit audio or video for multilingual dubbing, poll status, and download dubbed audio. Use when the user asks for dubbing, 多语言配音, 视频翻译配音, 译制片, or wants a source clip dubbed into another language.

ai-video-scriptSkill

Generate a structured short-video shooting script from a topic. Emits a strict, machine-parseable shot list (3 shots by default) with image prompt + video prompt + voiceover + on-screen text per shot. Trigger when the user asks for a video script, 分镜, 短视频文案, AI视频, 短剧脚本, or wants visual prompts ready for image/video generation.

cronSkill

Use when the user asks to schedule recurring tasks, one-off reminders, timers, or cron-style jobs through the OpenSquilla cron tool.

deep-researchSkill

Multi-round research with explicit methodology, evidence tracking, and citation-tagged synthesis. Trigger on 'deep dive', 'research report', 'literature review', 'investigate X across sources', 'multi-round investigation'. Distinct from the `summarize` skill, which is a single-pass condensation; this skill maintains a state file across iterations, tracks coverage, and produces a long-form report with per-claim citations. Three execution stages: plan (scope into sub-questions), iterate (record evidence per round), compile (synthesize report). The skill itself does not fetch the web — it tells the host agent which fetches to perform via OpenSquilla's existing web tools, and records what comes back.

docxSkill

Read, edit, or create Microsoft Word `.docx` files. Trigger this skill whenever the user mentions a Word document, .docx file, contract, report, brief, memo, or asks to extract text, modify an existing doc, generate one from a brief, or audit tracked changes. Three execution paths: text-and-structure extraction, in-place edit-by-run (preserves styles), and create-from-scratch with python-docx. Falls back to OOXML unzip-and-patch for layout work python-docx cannot reach.

git-diffSkill

Capture the current git diff (staged, working-tree, or staged file list) as text. Direct shell call for workflows that need repository diffs without an LLM agent loop.

githubSkill

GitHub operations via `gh` CLI: issues, PRs, CI runs, code review, API queries. Use when: (1) checking PR status or CI, (2) creating/commenting on issues, (3) listing/filtering PRs or issues, (4) viewing run logs. NOT for: complex web UI interactions requiring manual browser flows (use browser tooling when available), bulk operations across many repos (script with gh api), or when gh auth is not configured.

history-explorerSkill

Query the per-turn DecisionEntry log for skill co-occurrence patterns, meta-skill usage stats, and the router fixture corpus. Returns a JSON summary suitable for downstream LLM consumption. Used by meta-skill-creator's harvest step but also useful standalone for 'which skills did I use most this week?'
