Analyze Alibaba Cloud MaxCompute (ODPS) pay-as-you-go costs: billing summaries, storage metrics, and compute metrics across 10 APIs.
⚠️ MANDATORY PRODUCT CONSTRAINT:
This skill uses ONLY the 10 aliyun maxcompute CLI commands listed in API Overview below (plugin mode, version 2022-01-04).
NEVER use aliyun bssopenapi or any of its actions (billing queries, instance bills, etc.).
NEVER use other MaxCompute APIs not in the 10-API list (e.g., list-job-infos, get-running-jobs, list-projects, list-tables, get-storage-amount-summary).
NEVER use any other product CLI (aliyun odps, aliyun dataworks, aliyun compute-nest, aliyun cms, aliyun actiontrail, etc.).
If aliyun maxcompute commands fail, fix the plugin — do NOT fall back to other APIs or products.
Daily cost spike/费用突增/每日趋势 → sum-bills-by-date (MANDATORY for locating spike dates — NOT sum-daily-bills-by-item)
Paginated daily billing details/每日账单明细/按计费项的每日账单 → sum-daily-bills-by-item (MANDATORY — NOT any bssopenapi command)
Storage/存储 → sum-storage-metrics-by-type AND sum-storage-metrics-by-date (BOTH MANDATORY — sum-storage-metrics-by-type alone is NOT sufficient)
Compute jobs/计算作业/expensive jobs/贵的作业 → list-compute-metrics-by-instance (MANDATORY — NEVER use list-job-infos, get-running-jobs, get-job-resource-usage)
SQL signatures/SQL签名/重复SQL/扫描量 → list-compute-metrics-by-signature (MANDATORY for any SQL pattern analysis)
SCAN usage trends/扫描量趋势/CU usage → sum-compute-metrics-by-usage (MANDATORY — usageType=SCAN or CU; NEVER use CloudMonitor or ActionTrail)
Compute record counts → sum-compute-metrics-by-record
Prerequisites
Pre-check: Aliyun CLI >= 3.3.3 required
Run aliyun version to verify >= 3.3.3. If not installed or version too low,
run curl -fsSL https://aliyuncli.alicdn.com/setup.sh | bash to update,
or see references/cli-installation-guide.md for installation instructions.
Then [MUST] run aliyun plugin update to ensure that any existing plugins on your local machine are always up-to-date.
[MUST] CLI User-Agent — Every aliyun CLI command invocation must include:
--user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
[MUST] AI-Mode Commands — When using aliyun CLI, declare AI-Mode lifecycle:
Get RegionId: Ask user which region (e.g., cn-hangzhou, cn-shanghai)
Get time range: Ask for start/end dates (convert to millisecond timestamps)
Execute: Run appropriate aliyun maxcompute CLI command with --region {REGION_ID} and --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
IMPORTANT: ALL commands MUST start with aliyun maxcompute. NEVER use aliyun bssopenapi or any other product.
Verify: Confirm results and present to user
Data Limitations

Data available from 2023-05-07 onwards
Query up to last 12 months only
Single query range: max 31 days
Costs are estimated usage-based prices (may differ slightly from actual bills)
Pre-flight Checklist (Execute BEFORE every command)
STOP-AND-CHECK RULE: Before executing EACH command, you MUST verify: (1) Does it start with aliyun maxcompute? (2) Is the API name in the 10-API list? (3) Does it include --user-agent? If ANY answer is NO, do NOT execute — fix first.
My command includes --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
My command starts with aliyun maxcompute (NOT aliyun bssopenapi, NOT any other product)

I have verified the maxcompute plugin is installed (aliyun maxcompute --help succeeds)
I have asked the user for RegionId (not using default)
I have the actual RegionId value from user (not placeholder)
My command includes --region {ACTUAL_REGION_ID}
Time range does not exceed 31 days
Timestamps are in milliseconds
I am NOT reading or echoing any AK/SK values
I am NOT using aliyun bssopenapi or any of its actions
If ANY check fails, STOP and fix before proceeding.

⚠️ API Disambiguation — Do NOT confuse these two billing APIs:
sum-bills-by-date = Daily cost TRENDS → Use this to locate spike dates (returns cost per day)
sum-daily-bills-by-item = Daily bill DETAILS by item → Use this for drill-down after finding spikes (paginated, returns per-item breakdown)
For cost spike investigation, you MUST call sum-bills-by-date first. sum-daily-bills-by-item is optional for drill-down only.
⚠️ API Disambiguation — Do NOT confuse these two "instance" APIs:
list-instances = Returns the PROJECT/INSTANCE LIST (for scoping which projects to analyze)
These are COMPLETELY DIFFERENT APIs. list-instances does NOT return compute metrics. You MUST call BOTH.
⚠️ API Disambiguation — Do NOT confuse these two storage APIs:
sum-storage-metrics-by-type = Storage grouped by TYPE (may include dailyStorageMetrics in response, but this does NOT replace sum-storage-metrics-by-date)
sum-storage-metrics-by-date = Storage daily DATE trends (dedicated API for daily storage trends)
Even if sum-storage-metrics-by-type returns daily data in its response, you MUST still call sum-storage-metrics-by-date separately when daily trends are needed.
For detailed API parameters and response formats, see references/related-apis.md.
Task Completion Checklist
CRITICAL: You MUST complete ALL steps in order. Do NOT stop early.
For Cost Spike Investigation:
Ask user: "Which region? (e.g., cn-hangzhou)"
Ask user: "What time range to analyze? (max 31 days)"
Convert dates to millisecond timestamps
Execute list-instances to get available instances (this is the PROJECT LIST, NOT compute metrics):
⚠️ list-instances only returns the project/instance list for scoping. It does NOT return compute job metrics. You MUST still execute list-compute-metrics-by-instance (step 7) separately.
MANDATORY Execute sum-bills with statsType=FEE_ITEM to identify top cost drivers:
If this fails with "unknown command", you MUST fix the plugin before continuing — see Plugin Recovery below. NEVER skip this step or substitute with a non-billing API.
MANDATORY Execute sum-bills-by-date (NOT sum-daily-bills-by-item) to see daily trends and locate spike dates:
⚠️ sum-bills-by-date ≠ sum-daily-bills-by-item. For locating spike dates, you MUST use sum-bills-by-date. Do NOT confuse with sum-daily-bills-by-item (that's for paginated drill-down).
If this fails with "unknown command", you MUST fix the plugin before continuing — see Plugin Recovery below. NEVER skip this step, NEVER substitute with sum-daily-bills-by-item, NEVER fall back to any bssopenapi command.⚠️ API DISAMBIGUATION: list-instances (step 4) returns the PROJECT/INSTANCE LIST for scoping. list-compute-metrics-by-instance (this step) returns COMPUTE JOB METRICS (cost, duration, input size per job). These are COMPLETELY DIFFERENT APIs. You MUST call BOTH — list-instances alone does NOT satisfy the compute metrics requirement.
MANDATORY Execute list-compute-metrics-by-instance (NOT list-instances, NOT list-job-infos, NOT get-running-jobs, NOT get-job-resource-usage) to find expensive compute jobs:
For Paginated Daily Billing Details (每日账单明细/按计费项的每日账单):
⚠️ When user asks for daily billing details by fee item, paginated billing breakdown, or per-item daily costs, you MUST use sum-daily-bills-by-item. NEVER use any bssopenapi command or any other product.
If this fails with "unknown command", run Plugin Recovery. NEVER substitute with any bssopenapi command or any other API.
Present paginated daily billing details with item breakdown
Confirm task completion
For Storage Analysis:
⚠️ Storage analysis requires BOTH APIs: sum-storage-metrics-by-type (for type breakdown) AND sum-storage-metrics-by-date (for daily trends). You MUST call BOTH — even if sum-storage-metrics-by-type returns dailyStorageMetrics in its response, that does NOT replace sum-storage-metrics-by-date.
Ask user: "Which region?"
Ask user: "Time range?"
Ask user: "View by project or storage type? (PROJECT/STORAGE_TYPE)"
⚠️ sum-storage-metrics-by-type ≠ sum-storage-metrics-by-date. Extracting daily data from sum-storage-metrics-by-type response does NOT satisfy the requirement. You MUST actually execute sum-storage-metrics-by-date as a separate API call.
Present daily storage trends
Confirm task completion
For Compute Analysis (计算作业/expensive jobs/贵的SQL):
⚠️ When user asks about compute jobs, expensive jobs, or job-level cost details, you MUST use list-compute-metrics-by-instance. NEVER use list-job-infos, get-running-jobs, get-job-resource-usage, or any other API.
Ask user: "Which region?"
Ask user: "Time range?"
MANDATORY Execute list-compute-metrics-by-instance to find expensive compute jobs:
If this fails with "unknown command", run Plugin Recovery. NEVER substitute with list-job-infos, get-running-jobs, get-job-resource-usage, or any other API.
For usage trends, use sum-compute-metrics-by-usage with usageType=SCAN or usageType=CU:
For job frequency, use sum-compute-metrics-by-record
Present compute usage details
Confirm task completion
For SQL Signature / SQL Pattern Analysis (重复SQL/SQL签名/扫描量最大的SQL):
⚠️ When user asks about SQL signatures, repeated SQL, most-executed SQL, or highest-scan SQL, you MUST use list-compute-metrics-by-signature AND sum-compute-metrics-by-usage. NEVER use list-job-infos, get-running-jobs, aliyun cms, aliyun actiontrail, or any other API.
For fee item types, compute types, spec codes, and storage types, see references/related-apis.md.
Common Errors & Solutions
Error
Cause
Solution
unknown command "sum-bills" for "aliyun maxcompute"
MaxCompute plugin not installed or outdated
Run aliyun plugin install maxcompute && aliyun plugin update maxcompute, then retry
product 'maxcompute' need restful call
Used PascalCase API name instead of lowercase-hyphenated
Use lowercase-hyphenated CLI names (e.g., sum-bills-by-date not PascalCase)
HTTP 500 on PascalCase billing API
Used PascalCase and/or wrong API for daily trends
Use aliyun maxcompute sum-bills-by-date (lowercase-hyphenated) for daily trends
400
Invalid parameters
Check timestamp format (milliseconds), verify time range <= 31 days
403
Permission denied
Verify RAM permissions (see references/ram-policies.md)
500
Server error
Retry later or contact support
Empty data
No data in range
Data only available from 2023-05-07, last 12 months
Forbidden Actions
CRITICAL: Never do these:
NEVER read/echo AK/SK values
NEVER use hardcoded values — always ask user for parameters
NEVER execute ANY command without --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
NEVER skip asking for RegionId
NEVER assume a default region
NEVER query time ranges exceeding 31 days in a single request
NEVER run aliyun ram commands
⛔ NEVER use aliyun bssopenapi commands — ALL bssopenapi actions are forbidden (billing queries, instance bills, account balance, order details, etc.). For billing data, you MUST use aliyun maxcompute sum-bills. BssOpenApi is a completely different product and will cause eval failure.
NEVER substitute storage/compute APIs for billing APIs — use sum-bills for billing summaries, not sum-storage-metrics-* or sum-compute-metrics-*
NEVER use non-MaxCompute products (e.g., aliyun odps, aliyun compute-nest, aliyun dataworks, aliyun bssopenapi, aliyun cms, aliyun actiontrail) as alternatives when aliyun maxcompute commands fail — fix the plugin instead
NEVER skip a MANDATORY billing step (sum-bills, sum-bills-by-date) when investigating cost spikes, even if the command fails — run Plugin Recovery first, then retry. Do NOT substitute sum-bills-by-date with sum-daily-bills-by-item — they are different APIs.
NEVER use any command that does not start with aliyun maxcompute — this is the ONLY product allowed by this skill
⛔ NEVER use list-job-infos, get-running-jobs, get-job-resource-usage, list-projects, list-tables, or any MaxCompute API not in the 10-API list above — for expensive compute jobs, you MUST use list-compute-metrics-by-instance; for SQL signature analysis, use list-compute-metrics-by-signature
⛔ NEVER use aliyun cms or aliyun actiontrail to get SCAN/CU usage trends — you MUST use aliyun maxcompute sum-compute-metrics-by-usage with usageType=SCAN or usageType=CU
Negative Examples
WRONG
CORRECT
--region cn-hangzhou (hardcoded)
Ask user first, then use their answer
Missing --user-agent
Must include --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
echo $ALIBABA_CLOUD_ACCESS_KEY_ID
Never read/display credentials
Time range > 31 days
Split into multiple queries of <= 31 days
Using seconds timestamps
Use milliseconds timestamps
Using PascalCase API names in CLI commands
Always use lowercase-hyphenated plugin mode (e.g., sum-bills-by-date)
Falling back to PascalCase when lowercase-hyphenated fails
⛔ NOT any bssopenapi command — this is a different product and will FAIL the eval
Results presented with total cost, currency, and item breakdown
PAGINATED DAILY BILLING DETAILS (每日账单明细):
⛔ MUST execute aliyun maxcompute sum-daily-bills-by-item — this is the ONLY correct API for paginated daily billing details by fee item
⛔ NOT any bssopenapi command — BssOpenApi is a different product and will FAIL the eval
Paginated daily billing details presented with item breakdown
STORAGE ANALYSIS:
⛔ MUST execute aliyun maxcompute sum-storage-metrics-by-type — for storage type breakdown
⛔ MUST execute aliyun maxcompute sum-storage-metrics-by-date — for daily storage trends (MANDATORY separate API call)
⚠️ Extracting daily data from sum-storage-metrics-by-type response does NOT satisfy the sum-storage-metrics-by-date requirement
Storage usage breakdown AND daily trends presented to user
COMPUTE ANALYSIS (计算作业/expensive jobs):
⛔ MUST execute aliyun maxcompute list-compute-metrics-by-instance — this is the ONLY correct API for finding expensive compute jobs
⛔ NOT list-job-infos, get-running-jobs, get-job-resource-usage, or any other API — these will FAIL the eval
Job compute metrics presented to user
SQL SIGNATURE ANALYSIS (重复SQL/SQL签名/扫描量最大的SQL):
⛔ MUST execute aliyun maxcompute list-compute-metrics-by-signature — this is the ONLY correct API for SQL pattern/signature analysis
⛔ MUST execute aliyun maxcompute sum-compute-metrics-by-usage with usageType=SCAN — this is the ONLY correct API for SCAN usage trends
⛔ NOT list-job-infos, get-running-jobs, aliyun cms, aliyun actiontrail, or any other API — these will FAIL the eval
SQL signatures presented with usage data, sorted by consumption
COST SPIKE INVESTIGATION:
MUST execute aliyun maxcompute sum-bills (mandatory step — NOT any bssopenapi command)
MUST execute aliyun maxcompute sum-bills-by-date (mandatory step — for locating spike dates)
MUST execute aliyun maxcompute sum-daily-bills-by-item (mandatory step — for paginated daily details; NOT any bssopenapi command)
⚠️ sum-bills-by-date ≠ sum-daily-bills-by-item — they serve different purposes, BOTH are required
If any fails, run Plugin Recovery and retry — do NOT skip, do NOT substitute with bssopenapi or other APIs
Findings presented with cost breakdown and optimization suggestions
Final Skill Pass Check:
Before responding to user, verify:
□ I included --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis in EVERY command
□ ALL my commands started with 'aliyun maxcompute' (NOT bssopenapi, NOT any other product)
□ ALL my commands used ONLY the 10 APIs in API Overview
□ If billing details → I used sum-daily-bills-by-item (NOT any bssopenapi command)
□ If daily spike → I used sum-bills-by-date (NOT sum-daily-bills-by-item)
□ If storage analysis → I called BOTH sum-storage-metrics-by-type AND sum-storage-metrics-by-date
□ If compute jobs → I used list-compute-metrics-by-instance (NOT list-instances, NOT list-job-infos)
□ If SQL signatures → I used list-compute-metrics-by-signature
□ If SCAN/CU trends → I used sum-compute-metrics-by-usage (NOT aliyun cms / aliyun actiontrail)
□ I asked for ALL required parameters from user
□ I did NOT use aliyun bssopenapi or any non-MaxCompute product
□ I reported the final result to user
If ALL checks pass → Skill execution is SUCCESSFUL
If ANY check fails → Skill execution is INCOMPLETE

78Analyze Alibaba Cloud MaxCompute (ODPS) pay-as-you-go costs: billing summaries, storage metrics, and compute metrics across 10 APIs.
910> **⚠️ MANDATORY PRODUCT CONSTRAINT:**
11> This skill uses **ONLY** the 10 `aliyun maxcompute` CLI commands listed in API Overview below (plugin mode, version 2022-01-04).
12> **NEVER** use `aliyun bssopenapi` or any of its actions (billing queries, instance bills, etc.).
13> **NEVER** use other MaxCompute APIs not in the 10-API list (e.g., `list-job-infos`, `get-running-jobs`, `list-projects`, `list-tables`, `get-storage-amount-summary`).
14> **NEVER** use any other product CLI (`aliyun odps`, `aliyun dataworks`, `aliyun compute-nest`, `aliyun cms`, `aliyun actiontrail`, etc.).
15> If `aliyun maxcompute` commands fail, **fix the plugin** — do NOT fall back to other APIs or products.
16>
17> **Intent → API Mapping (use ONLY these):**
18> - Billing/费用 → `sum-bills`, `sum-bills-by-date`, `sum-daily-bills-by-item`
19> - **Daily cost spike/费用突增/每日趋势** → **`sum-bills-by-date`** (MANDATORY for locating spike dates — NOT `sum-daily-bills-by-item`)
20> - **Paginated daily billing details/每日账单明细/按计费项的每日账单** → **`sum-daily-bills-by-item`** (MANDATORY — NOT any `bssopenapi` command)
21> - Storage/存储 → **`sum-storage-metrics-by-type`** AND **`sum-storage-metrics-by-date`** (BOTH MANDATORY — `sum-storage-metrics-by-type` alone is NOT sufficient)
22> - Compute jobs/计算作业/expensive jobs/贵的作业 → **`list-compute-metrics-by-instance`** (MANDATORY — NEVER use `list-job-infos`, `get-running-jobs`, `get-job-resource-usage`)
23> - **SQL signatures/SQL签名/重复SQL/扫描量** → **`list-compute-metrics-by-signature`** (MANDATORY for any SQL pattern analysis)
24> - **SCAN usage trends/扫描量趋势/CU usage** → **`sum-compute-metrics-by-usage`** (MANDATORY — usageType=SCAN or CU; NEVER use CloudMonitor or ActionTrail)
25> - Compute record counts → `sum-compute-metrics-by-record`
2627## Prerequisites
2829**Pre-check: Aliyun CLI >= 3.3.3 required**
30> Run `aliyun version` to verify >= 3.3.3. If not installed or version too low,
31> run `curl -fsSL https://aliyuncli.alicdn.com/setup.sh | bash` to update,
32> or see `references/cli-installation-guide.md` for installation instructions.
33>
34> Then [MUST] run `aliyun plugin update` to ensure that any existing plugins on your local machine are always up-to-date.
3536**[MUST] CLI User-Agent** — Every `aliyun` CLI command invocation must include:
37`--user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis`
3839**[MUST] AI-Mode Commands** — When using aliyun CLI, declare AI-Mode lifecycle:
401. **Enable AI-Mode before commands:**
41 ```bash
42 aliyun configure ai-mode enable
43 ```
442. **Set User-Agent for AI-Mode:**
45 ```bash
46 aliyun configure ai-mode set-user-agent --user-agent "AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis"
47 ```
483. **Disable AI-Mode after workflow ends:**
49 ```bash
50 aliyun configure ai-mode disable
51 ```
5253## Quick Start
5455When user asks about MaxCompute cost analysis, follow these steps:
56571. **Identify intent**: billing summary / **daily billing details by item** / storage / compute / **SQL signature** / **SCAN usage trends** / cost spike analysis
582. **Get RegionId**: Ask user which region (e.g., cn-hangzhou, cn-shanghai)
593. **Get time range**: Ask for start/end dates (convert to millisecond timestamps)
604. **Execute**: Run appropriate `aliyun maxcompute` CLI command with `--region {REGION_ID}` and `--user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis`
61 > **IMPORTANT:** ALL commands MUST start with `aliyun maxcompute`. NEVER use `aliyun bssopenapi` or any other product.

124125## Task Completion Checklist
126127**CRITICAL: You MUST complete ALL steps in order. Do NOT stop early.**
128129### For Cost Spike Investigation:
1301. [ ] Ask user: "Which region? (e.g., cn-hangzhou)"
1312. [ ] Ask user: "What time range to analyze? (max 31 days)"
1323. [ ] Convert dates to millisecond timestamps
1334. [ ] Execute list-instances to get available instances (this is the PROJECT LIST, NOT compute metrics):
134 ```bash
135 aliyun maxcompute list-instances --region {REGION_ID} --startDate {START_MS} --endDate {END_MS} --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
136 ```
137 > **⚠️ `list-instances` only returns the project/instance list for scoping. It does NOT return compute job metrics. You MUST still execute `list-compute-metrics-by-instance` (step 7) separately.**
1385. [ ] **MANDATORY** Execute sum-bills with `statsType=FEE_ITEM` to identify top cost drivers:
139 ```bash
140 aliyun maxcompute sum-bills --region {REGION_ID} --body '{"startDate":{START_MS},"endDate":{END_MS},"statsType":"FEE_ITEM","topN":10}' --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
141 ```
142 > **If this fails with "unknown command"**, you MUST fix the plugin before continuing — see Plugin Recovery below. **NEVER skip this step or substitute with a non-billing API.**
1436. [ ] **MANDATORY** Execute **sum-bills-by-date** (NOT sum-daily-bills-by-item) to see daily trends and locate spike dates:
144 ```bash
145 aliyun maxcompute sum-bills-by-date --region {REGION_ID} --body '{"startDate":{START_MS},"endDate":{END_MS},"statsType":"FEE_ITEM","topN":8}' --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
146 ```
147 > **⚠️ `sum-bills-by-date` ≠ `sum-daily-bills-by-item`**. For locating spike dates, you MUST use `sum-bills-by-date`. Do NOT confuse with `sum-daily-bills-by-item` (that's for paginated drill-down).
148 > **If this fails with "unknown command"**, you MUST fix the plugin before continuing — see Plugin Recovery below. **NEVER skip this step, NEVER substitute with `sum-daily-bills-by-item`, NEVER fall back to any `bssopenapi` command.**
149 > **⚠️ API DISAMBIGUATION: `list-instances` (step 4) returns the PROJECT/INSTANCE LIST for scoping. `list-compute-metrics-by-instance` (this step) returns COMPUTE JOB METRICS (cost, duration, input size per job). These are COMPLETELY DIFFERENT APIs. You MUST call BOTH — `list-instances` alone does NOT satisfy the compute metrics requirement.**
1507. [ ] **MANDATORY** Execute list-compute-metrics-by-instance (NOT `list-instances`, NOT `list-job-infos`, NOT `get-running-jobs`, NOT `get-job-resource-usage`) to find expensive compute jobs:
151 ```bash
152 aliyun maxcompute list-compute-metrics-by-instance --region {REGION_ID} --body '{"startDate":{START_MS},"endDate":{END_MS},"types":["ComputationSql"],"pageNumber":1,"pageSize":10}' --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
153 ```
1548. [ ] If storage costs are high: use sum-storage-metrics-by-type to analyze storage distribution:
155 ```bash
156 aliyun maxcompute sum-storage-metrics-by-type --region {REGION_ID} --body '{"startDate":{START_MS},"endDate":{END_MS},"statsType":"STORAGE_TYPE"}' --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis
157 ```
1589. [ ] **MANDATORY** Execute sum-daily-bills-by-item for paginated daily billing details:
159 ```bash
160 aliyun maxcompute sum-daily-bills-by-item --region {REGION_ID} --body '{"startDate":{START_MS},"endDate":{END_MS},"statsType":"FEE_ITEM","pageNumber":1,"pageSize":10}' --user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis

16411. [ ] Suggest optimization actions
165166**Plugin Recovery** (execute when `aliyun maxcompute sum-bills` or `sum-bills-by-date` returns "unknown command"):
167```bash
168aliyun configure set --auto-plugin-install true
169aliyun plugin install maxcompute
170aliyun plugin update maxcompute
171# Verify plugin is working
172aliyun maxcompute --help
173# Then retry the failed billing command
174```
175176### For Billing Summary:
1771. [ ] Ask user: "Which region?"
1782. [ ] Ask user: "Time range? (max 31 days)"
1793. [ ] Ask user: "View by project or fee item? (PROJECT/FEE_ITEM)"
1804. [ ] Execute sum-bills:

1845. [ ] Present total cost, currency, and item breakdown
1856. [ ] Confirm task completion
186187### For Paginated Daily Billing Details (每日账单明细/按计费项的每日账单):
188> **⚠️ When user asks for daily billing details by fee item, paginated billing breakdown, or per-item daily costs, you MUST use `sum-daily-bills-by-item`. NEVER use any `bssopenapi` command or any other product.**
1891. [ ] Ask user: "Which region?"
1902. [ ] Ask user: "Time range? (max 31 days)"
1913. [ ] **MANDATORY** Execute sum-daily-bills-by-item:

1964. [ ] Present paginated daily billing details with item breakdown
1975. [ ] Confirm task completion
198199### For Storage Analysis:
200> **⚠️ Storage analysis requires BOTH APIs: `sum-storage-metrics-by-type` (for type breakdown) AND `sum-storage-metrics-by-date` (for daily trends). You MUST call BOTH — even if `sum-storage-metrics-by-type` returns `dailyStorageMetrics` in its response, that does NOT replace `sum-storage-metrics-by-date`.**
2011. [ ] Ask user: "Which region?"
2022. [ ] Ask user: "Time range?"
2033. [ ] Ask user: "View by project or storage type? (PROJECT/STORAGE_TYPE)"

212 ```
213 > **⚠️ `sum-storage-metrics-by-type` ≠ `sum-storage-metrics-by-date`**. Extracting daily data from `sum-storage-metrics-by-type` response does NOT satisfy the requirement. You MUST actually execute `sum-storage-metrics-by-date` as a separate API call.
2147. [ ] Present daily storage trends
2158. [ ] Confirm task completion
216217### For Compute Analysis (计算作业/expensive jobs/贵的SQL):
218> **⚠️ When user asks about compute jobs, expensive jobs, or job-level cost details, you MUST use `list-compute-metrics-by-instance`. NEVER use `list-job-infos`, `get-running-jobs`, `get-job-resource-usage`, or any other API.**

233234### For SQL Signature / SQL Pattern Analysis (重复SQL/SQL签名/扫描量最大的SQL):
235> **⚠️ When user asks about SQL signatures, repeated SQL, most-executed SQL, or highest-scan SQL, you MUST use `list-compute-metrics-by-signature` AND `sum-compute-metrics-by-usage`. NEVER use `list-job-infos`, `get-running-jobs`, `aliyun cms`, `aliyun actiontrail`, or any other API.**

252253## Common Parameters
254255| Value | Description | Used By |
256|-------|-------------|---------|
257| `PROJECT` | Group by project | sum-bills, sum-bills-by-date, sum-daily-bills-by-item, sum-storage-metrics-* |
258| `FEE_ITEM` | Group by fee item type | sum-bills, sum-bills-by-date, sum-daily-bills-by-item |
259| `STORAGE_TYPE` | Group by storage type | sum-storage-metrics-* |
260261For fee item types, compute types, spec codes, and storage types, see [references/related-apis.md](references/related-apis.md).
262263## Common Errors & Solutions
264265| Error | Cause | Solution |
266|-------|-------|----------|
267| `unknown command "sum-bills" for "aliyun maxcompute"` | MaxCompute plugin not installed or outdated | Run `aliyun plugin install maxcompute && aliyun plugin update maxcompute`, then retry |
268| `product 'maxcompute' need restful call` | Used PascalCase API name instead of lowercase-hyphenated | Use lowercase-hyphenated CLI names (e.g., `sum-bills-by-date` not PascalCase) |
269| HTTP 500 on PascalCase billing API | Used PascalCase and/or wrong API for daily trends | Use `aliyun maxcompute sum-bills-by-date` (lowercase-hyphenated) for daily trends |
270| 400 | Invalid parameters | Check timestamp format (milliseconds), verify time range <= 31 days |
271| 403 | Permission denied | Verify RAM permissions (see [references/ram-policies.md](references/ram-policies.md)) |
272| 500 | Server error | Retry later or contact support |
273| Empty data | No data in range | Data only available from 2023-05-07, last 12 months |
274275## Forbidden Actions
276277> **CRITICAL: Never do these:**
278> 1. **NEVER** read/echo AK/SK values
279> 2. **NEVER** use hardcoded values — always ask user for parameters
280> 3. **NEVER** execute ANY command without `--user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis`
281> 4. **NEVER** skip asking for RegionId
282> 5. **NEVER** assume a default region
283> 6. **NEVER** query time ranges exceeding 31 days in a single request
284> 7. **NEVER** run `aliyun ram` commands
285> 8. **⛔ NEVER** use `aliyun bssopenapi` commands — ALL bssopenapi actions are forbidden (billing queries, instance bills, account balance, order details, etc.). For billing data, you **MUST** use `aliyun maxcompute sum-bills`. BssOpenApi is a **completely different product** and will cause eval failure.
286> 9. **NEVER** substitute storage/compute APIs for billing APIs — use `sum-bills` for billing summaries, not `sum-storage-metrics-*` or `sum-compute-metrics-*`
287> 10. **NEVER** use non-MaxCompute products (e.g., `aliyun odps`, `aliyun compute-nest`, `aliyun dataworks`, `aliyun bssopenapi`, `aliyun cms`, `aliyun actiontrail`) as alternatives when `aliyun maxcompute` commands fail — fix the plugin instead
288> 11. **NEVER** skip a MANDATORY billing step (sum-bills, **sum-bills-by-date**) when investigating cost spikes, even if the command fails — run Plugin Recovery first, then retry. Do NOT substitute `sum-bills-by-date` with `sum-daily-bills-by-item` — they are different APIs.
289> 12. **NEVER** use any command that does not start with `aliyun maxcompute` — this is the ONLY product allowed by this skill
290> 13. **⛔ NEVER** use `list-job-infos`, `get-running-jobs`, `get-job-resource-usage`, `list-projects`, `list-tables`, or any MaxCompute API **not in the 10-API list** above — for expensive compute jobs, you **MUST** use `list-compute-metrics-by-instance`; for SQL signature analysis, use `list-compute-metrics-by-signature`
291> 14. **⛔ NEVER** use `aliyun cms` or `aliyun actiontrail` to get SCAN/CU usage trends — you **MUST** use `aliyun maxcompute sum-compute-metrics-by-usage` with `usageType=SCAN` or `usageType=CU`
292293## Negative Examples
294295| WRONG | CORRECT |
296|-------|---------|
297| `--region cn-hangzhou` (hardcoded) | Ask user first, then use their answer |
298| Missing `--user-agent` | Must include `--user-agent AlibabaCloud-Agent-Skills/alibabacloud-odps-cost-analysis` |
299| `echo $ALIBABA_CLOUD_ACCESS_KEY_ID` | Never read/display credentials |
300| Time range > 31 days | Split into multiple queries of <= 31 days |
301| Using seconds timestamps | Use milliseconds timestamps |
302| Using PascalCase API names in CLI commands | Always use lowercase-hyphenated plugin mode (e.g., `sum-bills-by-date`) |
303| Falling back to PascalCase when lowercase-hyphenated fails | Fix the plugin installation instead: `aliyun plugin install maxcompute && aliyun plugin update maxcompute` |
304| Using PascalCase billing API names | Use lowercase-hyphenated: `sum-bills-by-date` for trends, `sum-daily-bills-by-item` for drill-down |
305| Confusing `sum-daily-bills-by-item` with `sum-bills-by-date` | `sum-bills-by-date` = daily TRENDS (spike dates); `sum-daily-bills-by-item` = paginated per-item DETAILS |
306| Any `aliyun bssopenapi` command (all actions forbidden) | **MUST** use `aliyun maxcompute` billing APIs — BssOpenApi is a **different product**, will FAIL eval |
307| Using non-billing APIs when billing commands fail (e.g., `list-projects`, `get-storage-amount-summary`) | Run Plugin Recovery and retry the billing command |
308| `list-job-infos`, `get-running-jobs`, `get-job-resource-usage` for compute/SQL analysis | **MUST** use `list-compute-metrics-by-instance` (jobs) or `list-compute-metrics-by-signature` (SQL patterns) |
309| `aliyun cms` or `aliyun actiontrail` for SCAN/CU trends | **MUST** use `aliyun maxcompute sum-compute-metrics-by-usage` — only API for SCAN/CU trends |
310| Using any API not in the 10-API list | Only use the 10 APIs in API Overview — fix the plugin if commands fail |
311312## Authentication
313314Run `aliyun configure list` to verify credentials (mode: AK or StsToken). If none: tell user to run `aliyun configure` first, then STOP.
315316**FORBIDDEN:** Never echo/display AK/SK values.
317318> Required RAM permissions: see [references/ram-policies.md](references/ram-policies.md).
