@velinussage/locus-agent-skill

Install three Locus agent skills: the general MCP/REST/A2A capability guide, the opt-in surrounding-area purchase workflow, and the property-tax protest workflow.

Locus returns awareness and verification steps, not a verdict. Do not use it to score, rank, screen, value, predict, or label a person, property, block, or neighborhood as safe or unsafe.

Install with this package

npx @velinussage/locus-agent-skill add

By default this writes locus-agent-tools/, locus-surrounding-area-analysis/, and locus-property-tax-protest/ to $CODEX_HOME/skills or ~/.codex/skills. The general public skill routes relevant requests to the specialist workflows; it does not turn ordinary Locus discovery into a paid flow.

Options:

npx @velinussage/locus-agent-skill add --target ./skills
npx @velinussage/locus-agent-skill add --target ./skills --force
npx @velinussage/locus-agent-skill --print

Install with GitHub CLI

gh skill install velinussage/locus-agent-skill locus-agent-tools

Preview first:

gh skill preview velinussage/locus-agent-skill locus-agent-tools

Install with skills.sh

The same skill is also available from the public GitHub repo through the open skills CLI:

npx skills add velinussage/locus-agent-skill --skill locus-agent-tools

Useful variants:

npx skills add velinussage/locus-agent-skill --skill locus-agent-tools -g
npx skills add velinussage/locus-agent-skill --skill locus-agent-tools -a claude-code -a codex
npx skills use velinussage/locus-agent-skill --skill locus-agent-tools

What the skills teach agents

  • The full free catalog exposes 104 tools, including 58 national free lanes. Read the live catalog because rollout configuration can change the visible total.
  • locus_place_facts is the best first call when supported.
  • locus_lane_availability shows national, local, varies, not-covered, and degraded lanes before payment.
  • Free tools stay read-only and cited.
  • locus_rental_registration_check declares its scope per jurisdiction. Long-term registration is wired in Minneapolis, Montgomery County, New York City, and Seattle; Denver is short-term-license only; Kansas City is building-enforcement only. It returns no legal-rental or compliance verdict.
  • The property-tax protest workflow keeps deadline, filing-guide, evidence, browser handoff, and published-outcome facts separate from the owner's own filing and value position.
  • Paid endpoints use live x402 discovery, may offer USDC on Base and Solana, and require explicit user authorization. Agents choose one complete accepts[] entry.
  • The surrounding-area workflow requires two separate approvals: $0.10 for the reusable JSON packet, then $0.15 for an eligible HTML/PDF report within 24 hours. Packet and report retrieval are proof-gated for 90 days.

Qui maintient Locus ?

Il est publié par velinussage. AI.tn le référence sans le maintenir ni le recommander.

Issu du registre MCP officiel. Être listé n'est pas une recommandation : vérifiez le code et les permissions d'un serveur avant de lui donner accès à vos données.
