description
Use whenever the user asks about a motor-vehicle statute, citation, contributing factor, OR a Canadian personal-injury fact pattern — always query Specter's Harvester API before answering. The API auto-routes between two collections (US statutes + Canadian PI case law).
Specter's Harvester is a FastAPI service that fronts two Chroma collections:
Collection
Contents
When the API uses it
specter_statutes
384 US motor-vehicle statutes (CA, TX, FL, PA, IL, OH)
default — any US-jurisdiction or generic query
canada_pi_cases
340 real Canadian PI cases (CanLII, with damages, injury type, plaintiff_won, deciding_factor)
auto-routed when the query mentions Canada / Ontario / Quebec / Toronto / ONSC / ONCA / canlii / etc., or when ?jurisdiction=Canada or ?state=CA-CAN is passed
Every citation the user sees should come from the Harvester (or, on miss, from a verified web source). Never fabricate.
When to use this skill
Always for fact patterns mentioning Canada or a Canadian province / city. The Canada collection is indexed on facts of decided cases, so messy fact patterns ("child got hurt outside Target in Ontario", "slip and fall on icy sidewalk in Toronto") are EXACTLY what it's good at. Run search first; ask follow-ups only after showing what hit.
User asks for a specific citation: "what's Cal. Veh. Code § 23152(a)?" → lookup_citation
User asks a semantic / topical question: "DUI statutes in California", "laws about texting while driving" → search
User asks an open question and you want top-k candidates: "any state with a hit-and-run analog to CVC 20001?" → ask
User uses a synonym ("speeding", "drunk driving", "texting") — map it to one of the 17 canonical contributing-factor categories before passing as a factor filter (see categories below).
When NOT to use it
Pure procedural / case-strategy questions ("how do I file?") — the Harvester only holds statutes (US) and case law (Canada).
Greetings, identity questions, persona check-ins — answer in voice without calling the API.
Questions that don't require a citation (Specter can answer general PI-law-shape questions briefly without one, but must not invent a citation to back them up).
Important: don't gate behind clarification
For Canadian fact-pattern queries especially, call first with whatever the user said, even if it's vague. Show the top hits, THEN ask any follow-ups. The Canada corpus is fact-pattern-indexed — thin queries still return relevant cases. Demanding more facts before searching wastes the corpus.

How to call
The helper module sits next to this SKILL.md:
import sys
from pathlib import Path
sys.path.insert(0, str(Path(__file__).parent)) # if running ad hocfrom client import lookup_citation, search, ask, healthz, list_factors
In OpenClaw, prefer running it via exec:
cd ~/Specter && python3 -m openclaw.skills.harvester_query.client lookup "Cal. Veh. Code § 23152(a)"cd ~/Specter && python3 -m openclaw.skills.harvester_query.client search "drunk driving" --state CA --factor"DUI/DWI"cd ~/Specter && python3 -m openclaw.skills.harvester_query.client ask "what statutes cover hit and run in CA"
Or from Python:
from openclaw.skills.harvester_query.client import lookup_citation, search, ask
lookup_citation(citation: str) -> dict | None
Exact match by citation string. Returns the full record or None if not in the Harvester.
Same as search but framed as a question. Use this when the user hands you a natural-language query.
healthz() -> dict
Cheap liveness check. Use to confirm the API is running before reporting a miss.
list_factors() -> list[str]
The 17 categories. Useful for synonym mapping in voice.

Specter's voice rules (see SOUL.md): 2–3 lines max by default. Cite, don't quote.
Good:
Cal. Veh. Code § 22350. Basic speed law — drive no faster than reasonable for conditions.
leginfo.legislature.ca.gov
Bad:
Of course! Pursuant to California Vehicle Code Section 22350, "no person shall drive a vehicle…" (wall of text)
Always include the source_url from the record. Never include a citation without one — per hackathon ground rules, records without a real source URL don't count.
Miss handling
If lookup_citation returns None or search/ask returns []:
Check healthz() — if the API is down, say so plainly.
If the API is up but the record isn't there, say: "Not in the Harvester yet." Then either:
Offer to web-fetch from an authoritative source (legislatures, courts, bar associations only).
Suggest the team ingest that jurisdiction.
Never paper over a miss with a guess.
The 17 contributing-factor categories (canonical, do not invent)
DUI/DWI
Driving Too Fast For Conditions
Failure to Maintain Lane
Failure to Obey Traffic Control Device
Failure to Use/Activate Horn
Failure to Yield at a Yield Sign
Failure to Yield the Right-of-Way
Fleeing a Police Officer
Fleeing the Scene of a Collision
Following Too Closely
Improper Lane of Travel
Improper Passing
Improper Starting
Improper Stopping
Improper Turning
Reckless Driving
Using a Wireless Telephone/Texting While Driving
If the user uses a synonym, map internally and answer in their words.
