Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →
Supply Chain Security98
- No malware found by supply-chain analysis.Pass
- No known CVEs affecting this package version or its production dependencies.Pass
- No install/post-install scripts declared.Pass
- 31 of 99 dependencies flagged as unhealthy. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass

- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability66
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1008 tokens (~168/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management93
- Stability observed for 28 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial

- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 6 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
calculate_bazi_chart Calculate Bazi Chart ~376
Calculate a deterministic OpenFate Bazi/Four Pillars chart with True Solar Time correction, Day Master, DAYUN_SECOND_V2 onset receipts, Da Yun cycles, and branch interactions. Pass an exact birth time plus timezone or timezoneId for a calculated V2 onset; otherwise inspect the explicit unavailable/fallback receipt.
| Name | Type | Req | Description |
|---|---|---|---|
| calendarType | string | – | Input calendar type. |
| day | integer | yes | Birth day, 1-31. |
| dayBoundaryMode | string | – | Day-change rule. ZI_HOUR_23 means 23:00 starts the next day pillar. |
| dstOffset | number | – | Daylight saving offset in hours to remove from civil clock time. Use 1 for one-hour DST. |
| enableTrueSolarTime | boolean | – | Apply true solar time when longitude and timezone data are available. |
| gender | string | yes | Birth gender used for Da Yun direction. |
| hour | integer | – | Birth hour in local civil time, 0-23. Omit when birth time is unknown. |
| isLeapMonth | boolean | – | Whether the lunar input month is a leap month. Used only when calendarType is lunar. |
| longitude | number | – | Birthplace longitude in decimal degrees. Enables true solar time correction. |
| minute | integer | – | Birth minute in local civil time. |
| month | integer | yes | Birth month, 1-12. |

| timezone | number | – | UTC offset in hours for the birth clock time, such as 8 for China or -5 for US Eastern Standard Time. |
| timezoneId | string | – | Optional IANA timezone ID, such as Asia/Shanghai or America/New_York. |
| year | integer | yes | Birth year. Use the lunar year when calendarType is lunar. |
No output schema declared.
No examples provided.
calculate_true_solar_time Calculate True Solar Time ~143
Calculate OpenFate True Solar Time from civil birth time, longitude, timezone, and optional DST offset. Use this when explaining why the hour pillar may differ from ordinary clock-time tools.
| Name | Type | Req | Description |
|---|---|---|---|
| day | integer | yes | – |
| dstOffset | number | – | Daylight saving offset in hours. |
| hour | integer | yes | – |
| longitude | number | yes | Birthplace longitude in decimal degrees. |
| minute | integer | – | – |

| year | integer | yes | – |
No output schema declared.
No examples provided.
detect_bazi_interactions Detect Bazi Interactions ~207
Detect raw Earthly Branch relationship occurrences for a natal chart and optional annual and Da Yun branches. Preserves every matching pillar position, including repeated branches. Covers clashes, six-combinations, the eight central-branch half-trines (COMBINATION_HALF), full trines, directionals, punishments, destructions, and harms. Results establish relationship presence, not weights, cancellation, or automatic transformation; targetElement is an affinity, not transformed energy.
| Name | Type | Req | Description |
|---|---|---|---|
| annualBranch | – | – | Optional annual or target branch. Preserved as the annual pillar role, independently of repeated natal branches. |
| dayBranch | string | yes | Natal day branch. |
| dayunBranch | – | – | Optional Da Yun branch. Preserved as the dayun pillar role, independently of the annual and natal branches. |
| hourBranch | string | – | Natal hour branch. Omit when birth time is unknown. |
| monthBranch | string | yes | Natal month branch. |
| yearBranch | string | yes | Natal year branch. |
No output schema declared.
No examples provided.
get_openfate_bazi_policy Get OpenFate Bazi Policy ~29

|---|---|---|---|
| bazi | string | yes | Four pillars separated by spaces, for example: 戊寅 己未 己卯 辛未. |
| dayBoundaryMode | string | – | Day-change rule used during lookup. |
