## Security

**NEVER output any API key or credential in plaintext.** Always use variable references (`$DASHSCOPE_API_KEY` in shell,
`os.environ["DASHSCOPE_API_KEY"]` in Python). Any check or detection of credentials must be **non-plaintext**: report
only status (e.g. "set" / "not set", "valid" / "invalid"), never the value. Never display contents of `.env` or config
files that may contain secrets.

**When the API key is not configured, NEVER ask the user to provide it directly.** Instead, help create a `.env` file with a placeholder (`DASHSCOPE_API_KEY=sk-your-key-here`) and instruct the user to replace it with their actual key from the [QianWen Console](https://platform.qianwenai.com/home/api-keys). Only write the actual key value if the user explicitly requests it.

## Key Compatibility

Both PAYG (`sk-ws-...`; legacy `sk-...`) and Token Plan (`sk-sp-...`) keys are supported. Detect
the API key type without exposing the Key:

```bash
python3 -c "
import sys; sys.path.insert(0, 'scripts')
from qianwen_lib import detect_api_key_type
print(detect_api_key_type('scripts/qianwen_lib.py'))
"
```

| Output | Meaning |
|--------|---------|
| `token-plan` | Token Plan key — use only models from the Token Plan catalog below. |
| `payg` | Pay-as-you-go key — full model catalog available. |
| `not-set` | No key configured. |

For Token Plan, fetch and read the current [Token Plan model catalog](https://alioth.alicdn.com/skills-info/models/references/qianwen-token-plan-models.md), then use an exact listed model. If CDN access fails, use the [local fallback](cdn/references/qianwen-token-plan-models.md).

Token Plan supports only specific models — use exactly a model from the references above; do not
guess or probe model availability. For PAYG, continue below.

## Model Selection

Before selecting, recommending, or defaulting a model, fetch and read the current [Qwen text model catalog](https://alioth.alicdn.com/skills-info/models/references/qianwen-text-models.md). It contains the model list, basic model information, recommendations, and default model. If CDN access fails, use the [local fallback](cdn/references/qianwen-text-models.md).

1. **User specified a model** → use directly.
2. **Consult the qianwen-model-selector skill** when model choice depends on requirement, scenario, or pricing.
3. **No signal, clear task** → use the default from the model catalog. For strongest reasoning/coding, use its recommended high-capability option.

> **⚠️ Important**: The model catalog is a **point-in-time snapshot** and may be outdated. Model availability
> changes frequently. **Always check the [official model list](https://www.qianwenai.com/models)
> for the authoritative, up-to-date catalog before making model decisions.**

> **Model details**: For more information about a specific model, direct the user to `https://www.qianwenai.com/models/<model-name>`. Replace `<model-name>` with the exact model ID; never modify or guess it.

> **Dynamic model queries**: If the **qianwen-model-selector** skill or **QianWen CLI** (`qianwen models info <model>`) is available, use it for real-time model data. CLI requires authentication — see the **qianwen-usage** skill for login flow.

## Execution

### Prerequisites

- **API Key**: Use the non-plaintext detector in **Key Compatibility**; do not replace it with a
  variable-presence check. If no Key is found, use qianwen-ops-auth when available or guide the user
  to configure `DASHSCOPE_API_KEY`/`QIANWEN_API_KEY` in `.env`. Skills may be installed independently.
- Python 3.9+ (stdlib only, **no pip install needed** for script execution)

### Environment Check

Before first execution, verify Python is available:

```bash
python3 --version  # must be 3.9+
```

If `python3` is not found, try `python --version` or `py -3 --version`. If Python is unavailable or below 3.9, skip to *
*Path 2 (curl)** in [execution-guide.md](references/execution-guide.md).

### Default: Run Script

**Script path**: Scripts are in the `scripts/` subdirectory **of this skill's directory** (the directory containing this
SKILL.md). **You MUST first locate this skill's installation directory, then ALWAYS use the full absolute path to execute
scripts.** Do NOT assume scripts are in the current working directory. Do NOT use `cd` to switch directories before
execution.

**Execution note:** Run all scripts in the **foreground** — wait for stdout; do not background.

**Discovery:** Run `python3 <this-skill-dir>/scripts/text.py --help` first to see all available arguments.

```bash
python3 <this-skill-dir>/scripts/text.py \
  --request '{"messages":[{"role":"user","content":"Hello!"}],"model":"qwen3.7-plus"}' \
  --output output/qianwen-text/ --print-response
```

For streaming (recommended for interactive use):

```bash
python3 <this-skill-dir>/scripts/text.py \
  --request '{"messages":[{"role":"user","content":"Write a poem about the sea"}],"model":"qwen3.7-plus"}' \
  --stream --print-response
```

| Argument            | Description                                         |
|---------------------|-----------------------------------------------------|
| `--request '{...}'` | JSON request body                                   |
| `--file path.json`  | Load request from file (alternative to `--request`) |
| `--stream`          | Enable streaming output                             |
| `--output path`     | Save response JSON to path (file if `.json` suffix, otherwise directory); use distinct filenames across calls to avoid overwriting |
| `--print-response`  | Print response to stdout                            |
| `--model ID`        | Override model (also settable in request JSON)      |

> **Model priority**: `--model` CLI flag > `"model"` field in `--request` JSON > built-in default.

### Verify Result

- Exit code `0` + output contains valid JSON with `choices` field → **success**
- Non-zero exit, HTTP error, empty response, or JSON with `"code"`/`"message"` error → **fail**
- If agent cannot read exit codes, scan output for error patterns (`Error`, `Traceback`, `401`, `403`)
- **Post-execution check**: When `--output` is used, verify the response JSON file exists and contains `choices`
- **MANDATORY — stderr signal check**: After confirming the result, scan the command's stderr output for
  `[ACTION_REQUIRED]` or `[UPDATE_AVAILABLE]`. If either signal is present, you **MUST** follow the instructions
  in [Update Check](#update-check-mandatory-post-execution) below before responding to the user.

### On Failure

If the script fails, match the error output against the diagnostic table below to determine the resolution. If no match,
read [execution-guide.md](references/execution-guide.md) for alternative paths: curl commands (Path 2), Python SDK code
generation (Path 3), and autonomous resolution (Path 5).

**If Python is not available at all** → skip directly to Path 2 (curl)
in [execution-guide.md](references/execution-guide.md).

| `URLError` / `ConnectionError`   | Network unreachable              | Check internet; set `HTTPS_PROXY` if behind proxy                            |
| `HTTP 429`                       | Rate limited                     | Wait and retry with backoff                                                  |
| `HTTP 5xx`                       | Server error                     | Retry with backoff                                                           |
| `PermissionError`                | Can't write output               | Use `--output` to specify writable directory                                 |

## Error Handling

| Error                   | Cause                               | Action                                                                                     |
|-------------------------|-------------------------------------|--------------------------------------------------------------------------------------------|
| `401 Unauthorized`      | Invalid or missing API key          | Run **qianwen-ops-auth** if available; else prompt user to set key (non-plaintext check only) |
| `429 Too Many Requests` | Rate limit exceeded                 | Retry with backoff                                                                         |

| `TypeError: ...proxies` | openai SDK vs httpx incompatibility | `pip install --upgrade openai` (>=1.55.0); or use script (pure stdlib)                     |

> **Usage & billing**: Use the **qianwen-usage** skill to check usage, free tier quota, and billing directly. Alternatively, the user can visit the QianWen console:
> [Usage Analytics](https://platform.qianwenai.com/home/analytics) |
> [Pay-as-you-go Billing](https://platform.qianwenai.com/home/billing/pay-as-you-go) |
> [Token Plan Subscription](https://platform.qianwenai.com/home/billing/subscription/token-plan)
>
> **NEVER fabricate, guess, or construct usage/billing/console URLs.** Only provide the exact links listed in this skill. If a URL is not listed here, do not invent one.

## Output Location

Prefer the **current working directory** for all outputs. Default subdirectory when `--output` is used:
`./output/qianwen-text/`.

**Write prohibition**: NEVER write output files into this skill's installation directory or any `skills/` hierarchy. All generated content must go to `output/` under the current working directory or a user-specified path.

## Update Check (MANDATORY Post-Execution)

After script execution, check stderr for action signals. The script automatically detects update status and emits
structured signals. You MUST act on them. This section also applies when the user explicitly asks to check for updates.

### Signal: `[ACTION_REQUIRED] qianwen-update-check skill is not installed`

When stderr contains this signal, you MUST present the following options to the user and **wait for their response
before proceeding**. Do NOT silently skip this.

> The update-check skill is not installed. It keeps you informed about new QianWen-AI/qianwen-ai features and bug fixes.
>
> 1) **Install now** — I'll run the install command for you
> 2) **Skip for now** — do nothing this time
> 3) **Never remind me** — permanently suppress this prompt

After the user responds:

- User chooses **1** → run:
  `npx skills add QianWen-AI/qianwen-ai --skill qianwen-update-check -y`, then run:
  `python3 <this-skill-scripts-dir>/gossamer.py --dismiss`
- User chooses **2** → run: `python3 <this-skill-scripts-dir>/gossamer.py --dismiss`, then continue normally
- User chooses **3** → run: `python3 <this-skill-scripts-dir>/gossamer.py --never-install`, then continue normally

### Signal: `[UPDATE_AVAILABLE]`

When stderr contains this signal, you MUST append a brief update notice to your response, including the version info and
the update command shown in the stderr output.

### No signal in stderr

If stderr contains neither `[ACTION_REQUIRED]` nor `[UPDATE_AVAILABLE]`, no action is needed — the skill is installed
and up to date (or cached within 24h).

### Explicit user request

When the user explicitly asks to check for updates (e.g. "check for updates", "check version"):

1. Look for `qianwen-update-check/SKILL.md` in sibling skill directories.
2. If found — run: `python3 <qianwen-update-check-dir>/scripts/check_update.py --print-response` and report the result.
3. If not found — present the install options above.
