Authentication: No configuration needed on first use. The CLI handles non-TTY detection and safe login automatically (see Authentication Flow below).

Environment Variables

Variable	Description
`QWENCLOUD_KEYRING`	Set to `plaintext`, `no`, `0`, `false`, or `off` to opt out of OS keychain credential storage.
`QWENCLOUD_CREDENTIALS_DIR`	Override file-based credential directory (default: `~/.qwencloud/credentials`).

Authentication Flow (for Agents)

The CLI auto-detects non-TTY environments and degrades safely — no wrapper script needed.

TL;DR — 3-step auth path

qwencloud auth status --format json → authenticated: true → skip to commands
qwencloud auth login --init-only --format json → extract verification_url → open in browser
qwencloud auth login --complete --format json → poll until success event

Quick check: already logged in?

qwencloud auth status --format json

If authenticated: true and token is not expired, skip login entirely.

Recommended: Two-phase login

Works in all environments (desktop, headless, remote container).

Step 1 — Initialize login (non-blocking):

qwencloud auth login --init-only --format json

Exits immediately. Parse the stdout JSON events array:

already_authenticated → user is logged in, skip to commands
device_code → extract verification_url and present it to the user

On desktop environments with a browser, open the URL for the user:

open "$VERIFICATION_URL"          # macOS
xdg-open "$VERIFICATION_URL"      # Linux
start "" "$VERIFICATION_URL"      # Windows

Step 2 — IMMEDIATELY start polling (do NOT wait for user confirmation):

qwencloud auth login --complete --format json

Parse the stdout JSON events array:

success → login complete, proceed to commands
expired → device code expired, go back to Step 1
error → report failure

TTY environments (interactive terminal)

If the agent is running in a TTY (e.g., user's terminal), simply run:

qwencloud auth login

The CLI will automatically open the browser and poll until authorization completes.

JSON event structure

Both --init-only and --complete output a single JSON document:

{
  "events": [
    {"event": "device_code", "verification_url": "...", "expires_in": 300},
    {"event": "success", "authenticated": true, "user": {"aliyunId": "..."}}
  ]
}

Event types: already_authenticated, device_code, success, expired, error, pending.

NEVER:

❌ Ask the user "Have you completed authorization?" before running --complete
❌ Wait for user confirmation before polling — run --complete immediately after presenting the URL
❌ Re-run --init-only without completing (this creates a new device code and invalidates the previous one)

Usage

All commands support --format json for structured, machine-parseable output (recommended default), and --format text for clean plaintext output.

For agent use, always prefer --format json and parse the JSON response. Only fall back to --format text when the user explicitly requests human-readable plaintext.

Never parse table format programmatically — it contains ANSI codes and Unicode borders.

Breakdown Parameters: How to Think About Them

Three independent dimensions — combine them freely:

--model (required) + date range + granularity

Model scope:

--model <id> — single model (e.g. qwen3.5-plus); required for breakdown

Date range — three patterns, pick by how the user described the period:

Pattern	When to use	How it works
`--period YYYY-MM`	User names a specific month ("March", "last April")	Exact calendar month, start to end
`--period <preset>`	User describes a relative period	`last-month` = previous full month; `month` = this month so far; `quarter` = this calendar quarter so far
`--days N`	User says "last N days"	Rolling window backwards from today, crosses month boundaries naturally
`--from YYYY-MM-DD --to YYYY-MM-DD`	User gives explicit dates or a named quarter/range	Full control, use when other patterns don't fit

Granularity — determines the grouping of results, not the range:

day (default) — one row per day; good for spotting usage spikes
month — one row per calendar month; good for multi-month trends
quarter — one row per quarter; good for Q-over-Q comparison

Classic examples:

# Single model, single month, daily detail
qwencloud usage breakdown --model qwen3.5-plus --period 2026-03

# Single model, last 3 months, monthly summary
qwencloud usage breakdown --model qwen3.5-plus --days 90 --granularity month

# Single model, specific quarter, quarterly rollup
qwencloud usage breakdown --model qwen3.5-plus --from 2026-01-01 --to 2026-03-31 --granularity quarter

# Single model, this month, daily breakdown
qwencloud usage breakdown --model qwen3.6-plus --period month

Output and Agent Display Rules

CLI commands return JSON by default in agent/pipe environments (auto format: TTY → table, pipe → json). JSON is the primary output mode for agents — always pass --format json explicitly, parse the structured response, then present a human-readable summary to the user.

JSON output example (`--format json`)

qwencloud usage summary --period month --format json

Returns structured JSON with three sections:

{
  "period": { "from": "2026-04-01", "to": "2026-04-24" },
  "free_tier": [
    { "model_id": "qwen3.6-plus", "quota": { "remaining": 850000, "total": 1000000, "unit": "tokens", "used_pct": 15 } }
  ],
  "coding_plan": {
    "subscribed": true,
    "plan": "PRO",
    "windows": {
      "per_5h": { "remaining": 4800, "total": 6000, "used_pct": 20 },
      "weekly": { "remaining": 38200, "total": 45000, "used_pct": 15 },
      "monthly": { "remaining": 82500, "total": 90000, "used_pct": 8 }
    }
  },
  "pay_as_you_go": {
    "models": [
      { "model_id": "qwen3.6-plus", "usage": { "tokens_total": 480000 }, "cost": 0.38, "currency": "USD" },
      { "model_id": "qwen-plus", "usage": { "tokens_total": 460000 }, "cost": 0.13, "currency": "USD" }
    ],
    "total": { "cost": 0.51, "currency": "USD" }
  }
}

⚠️ CRITICAL: How to present output to the user

When using --format json (recommended for agents):

Parse the JSON and extract the relevant data for the user's question
Present a human-readable summary — do not dump raw JSON to the user
Add analysis AFTER the summary — clearly separated with ---

When using --format text:

Display CLI output EXACTLY AS-IS — no modification, no reformatting
Preserve all formatting — alignment, spacing, progress bars, separators
Add analysis AFTER output only — clearly separated with ---

NEVER:

❌ Dump raw JSON to the user without interpretation
❌ Reformat or summarize text/table output
❌ Add prefixes like "Here's your usage:"
❌ Convert text/table output to bullet points

✅ CORRECT (JSON mode):

Your QwenCloud usage for April:

**Free Tier**: qwen3.6-plus has 85% remaining (850K / 1M tokens), wan2.6-t2i has 76% remaining (38 / 50 images).
**Coding Plan (PRO)**: 8% used this month (82.5K / 90K requests).
**Pay-as-you-go**: $0.51 total — qwen3.6-plus $0.38, qwen-plus $0.13.

---

**💡 Analysis**: Your qwen3.6-plus free tier is 85% remaining...

✅ CORRECT (Text mode):

[CLI text output - exactly as-is]

---

**💡 Analysis**: Your qwen3.6-plus free tier is 85% remaining...

❌ WRONG:

Here's your usage:
- qwen3.6-plus: 850K tokens remaining (85% left)

Exit Codes

Code	Meaning
0	Success
1	General/usage error
2	Authentication error
3	Network error
4	Configuration error
130	Interrupted

CLI Update Check

When the user explicitly asks to check for cli updates (e.g. "check for cli updates", "check cli version", "is there a new version cli"):

Run: qwencloud version --check
Report the result.

The QwenCloud CLI handles update notifications natively; no additional stderr signal handling is required in this skill.

Implementation Notes

Pay-as-you-go: API returns total usage only (no input/output split)
Coding Plan: Aggregate request counts at plan level (no per-model breakdown)
logout: Revokes server-side session and clears local credentials (keychain + file). Server-side call is best-effort — local logout always succeeds.
Authentication: Uses OAuth 2.0 Device Authorization Grant with PKCE. Credentials stored in OS keychain when available, with encrypted file fallback.
breakdown --model is required: Unlike the previous Python implementation, the CLI requires --model for breakdown. To query all models' usage, use qwencloud usage summary instead.
