@ghostpaw/affinity

@ghostpaw/affinity

Agent contacts: people, promises and yearly dates, with a radar for who is drifting.

A local social CRM: contacts, identities, relationships, journal events, commitments and recurring dates in one SQLite file. One self-contained binary per platform, an MCP server, and a zero-dependency TypeScript library.

Install

Each line downloads the latest release for one platform, checks it against SHA256SUMS, puts ghostpaw-affinity on your PATH and prints the version.

Linux installs to ~/.local/bin (added to ~/.profile if missing), macOS to /usr/local/bin (asks for sudo), Windows to %LOCALAPPDATA%\Programs\ghostpaw\bin (added to the user PATH; open a new terminal afterwards).

Then:

ghostpaw-affinity contact create '{"name":"Sam","kind":"human"}'
ghostpaw-affinity search sam
ghostpaw-affinity skill            # cheat sheet and tool reference

Contacts live in ~/.ghostpaw/affinity.db unless --db <path> or the GHOSTPAW_AFFINITY_DB environment variable says otherwise; relative paths resolve against the current directory.

A session with the linux-x64 binary against a fresh database:

The same session as an animated GIF.

npx / npm (for npm-based environments)

The npm package needs Node 24+ and has zero runtime dependencies:

npx -y @ghostpaw/affinity --help
npm install -g @ghostpaw/affinity   # provides ghostpaw-affinity

Library (for harnesses)

npm install @ghostpaw/affinity

import { DatabaseSync } from "node:sqlite";
import { initAffinityTables, read, write, tools } from "@ghostpaw/affinity";

See Quick Start and docs/LLM.md for the tool facade.

Other installers and verification

Interactive installers (also verify SHA256SUMS):

curl -fsSL https://raw.githubusercontent.com/GhostPawJS/affinity/main/install.sh | sh

irm https://raw.githubusercontent.com/GhostPawJS/affinity/main/install.ps1 | iex

mise use -g github:GhostPawJS/affinity
ubi --project GhostPawJS/affinity --exe ghostpaw-affinity --in ~/.local/bin
eget GhostPawJS/affinity

For aqua, define a github_release package in aqua.yaml:

registries:
  - name: affinity
    type: local
    path: affinity-registry.yaml
packages:
  - name: GhostPawJS/affinity@v<VERSION>
    registry: affinity

affinity-registry.yaml:

packages:
  - type: github_release
    repo_owner: GhostPawJS
    repo_name: affinity
    asset: ghostpaw-affinity-{{trimV .Version}}-{{.OS}}-{{.Arch}}.tar.gz
    format: tar.gz
    replacements: { amd64: x64 }
    overrides:
      - goos: windows
        asset: ghostpaw-affinity-{{trimV .Version}}-windows-{{.Arch}}.zip
        format: zip
    files:
      - name: ghostpaw-affinity

SHA256SUMS covers every archive and server.mcpb. To verify a downloaded archive's build attestation:

gh attestation verify <archive> -R GhostPawJS/affinity

Set GHOSTPAW_VERIFY=attestation for attestation verification in install.sh. Binaries are unsigned; macOS binaries carry an ad-hoc signature. For a browser download on macOS, remove quarantine with xattr -d com.apple.quarantine /path/to/ghostpaw-affinity. Linux binaries require glibc 2.28+; use npx on Alpine. See the binary build workflow.

Each archive is roughly 40-46 MB (the binary embeds the Node runtime, 105-150 MB unpacked); the npm package is about 2 MB unpacked. Every release, including the one-liners above, is installed and run on ubuntu-24.04, macos-15 and windows-2025 by the install check.

MCP server

Every client below starts the same stdio server: ghostpaw-affinity mcp. Without the binary, use npx -y @ghostpaw/affinity mcp as the command instead.

Claude Code

claude mcp add ghostpaw-affinity -- ghostpaw-affinity mcp

or as a plugin, which also installs the skill:

/plugin marketplace add GhostPawJS/affinity
/plugin install ghostpaw-affinity@ghostpaw-affinity

Codex CLI (~/.codex/config.toml)

[mcp_servers.ghostpaw-affinity]
command = "ghostpaw-affinity"
args = ["mcp"]

Cursor (.cursor/mcp.json), Claude Desktop (claude_desktop_config.json) or a project .mcp.json:

{
  "mcpServers": {
    "ghostpaw-affinity": {
      "command": "ghostpaw-affinity",
      "args": ["mcp"]
    }
  }
}

Claude Desktop users can also install server.mcpb from the latest GitHub release. A Dockerfile is included for container hosts: docker build -t ghostpaw-affinity . && docker run -i --rm -v affinity:/data ghostpaw-affinity.

The server speaks MCP 2026-07-28 (stateless, server/discover) and the initialize-based revisions 2025-11-25, 2025-06-18, 2025-03-26 and 2024-11-05.

Agent Skill

SKILL.md (repo root) and skills/affinity/SKILL.md follow the Agent Skills format and ship in the npm package. Copy skills/affinity/ into your agent's skills folder, or print it:

ghostpaw-affinity skill > SKILL.md
ghostpaw-affinity skill --list       # workflow guides
ghostpaw-affinity skill bootstrap-and-cold-start

CLI

export GHOSTPAW_AFFINITY_DB=~/crm/affinity.db      # or --db <path>
ghostpaw-affinity contact create '{"name":"Fox","kind":"human","bootstrapOwner":true}'
ghostpaw-affinity search "jana"                     # names, identities, tags, attributes, roles, events
ghostpaw-affinity contact create '{"name":"Jana Petersen","kind":"human"}'
ghostpaw-affinity identity add --contact '{"contactId":2}' --input '{"type":"email","value":"[e-mail]"}'
ghostpaw-affinity event record --kind interaction --input '{"type":"conversation","occurredAt":"today","summary":"Call re pilot","significance":6,"participants":[{"contactId":2,"role":"recipient","directionality":"mutual"}]}'
ghostpaw-affinity commitment record --input '{"commitmentType":"promise","occurredAt":"today","dueAt":"+3d","summary":"Send proposal","significance":6,"participants":[{"contactId":2,"role":"recipient"}]}'

There are 29 domain commands. review accepts the existing view names, including contacts.list, contacts.duplicates and dates.upcoming. show selects an inspection kind; contact and link locators are JSON objects. Use help contact or contact create --help for schema-derived help; a mistyped command suggests the closest one. Nested payloads use JSON or @path to read a file; repeated array flags accept JSON objects (--entries '{"name":"a","value":"x"}') or one JSON array.

Every time field accepts epoch milliseconds, ISO 8601 with Z or an offset, YYYY-MM-DD, DD.MM.YYYY (CLI), today, tomorrow, yesterday and signed day offsets such as +3d or -2d. On the CLI, date-only values use local time (midnight, or end of day for dueAt); through MCP and the tool facade they use UTC.

Global flags: --db <path>, --json, --quiet, --compact, --help/-h, --version/-V/-v, --no-color. NO_COLOR is accepted. In a terminal, commands print a readable summary with names and dates. With --json or piped stdout they print the tool result as JSON with ISO date siblings and floats rounded to three decimals; --compact removes indentation and empty receipt arrays. --quiet suppresses stdout. Writes list what changed in data.changes, and creates warn about likely duplicates. Kebab-case flags map to schema properties. -- ends flags. A positional -, or piped stdin when no other arguments are given, reads a JSON object (echo '{"name":"Sam","kind":"human"}' | ghostpaw-affinity contact create). Explicit flags override stdin fields. Database selection uses --db, GHOSTPAW_AFFINITY_DB, then ~/.ghostpaw/affinity.db; relative paths resolve against the current directory, and --help shows the resolved path. A new database is reported on stderr. These commands work offline.

Exit	Result
0	Success, including no_op
1	Other tool error
2	Usage, schema or invalid input
3	Clarification needed or not found
4	Conflict, already resolved or version mismatch
70	Internal error

Errors go to stderr. With --json, errors also print to stdout. --version names the variant: affinity 0.5.0 (binary, linux-x64), (npm) or (library). Legacy tools [--json], describe <tool>, call <tool> [JSON|-] and <tool_name> --parameter value remain available. completions bash|zsh|fish prints shell scripts.

Quick Start

import { DatabaseSync } from "node:sqlite";
import { initAffinityTables, read, write } from "@ghostpaw/affinity";

const db = new DatabaseSync(":memory:");
db.exec("PRAGMA foreign_keys = ON");
initAffinityTables(db);

const { primary: owner } = write.createContact(db, {
  name: "Mika",
  kind: "human",
  bootstrapOwner: true,
});

const { primary: ada } = write.createContact(db, {
  name: "Ada Lovelace",
  kind: "human",
});

write.addIdentity(db, ada.id, {
  type: "email",
  value: "[e-mail]",
});

write.recordInteraction(db, {
  type: "conversation",
  occurredAt: Date.now(),
  summary: "Coffee together",
  significance: 6,
  participants: [
    { contactId: owner.id, role: "actor", directionality: "mutual" },
    { contactId: ada.id, role: "recipient", directionality: "mutual" },
  ],
});

const profile = read.getContactProfile(db, ada.id);
const radar = read.listRadar(db);

Docs

The live demo runs the library in your browser against an in-memory SQLite database. Each view below opens a different part of it:

• Dashboard: overview and session
• Contacts: people, companies, groups and pets you track
• Relationships: links, rank and bonds
• Timeline: events, commitments and date anchors
• Insights: radar and analytics

The Model

Eight concepts, strict separation of concerns:

Concept	Purpose
Contact	Any tracked entity: person, company, team, service, pet, household, or group
Identity	Exact recognition and routing handle such as email, phone, URL, or account id
Social Link	A live relationship track with Rank, Affinity, Trust, cadence, Bond, and state
Tie	A structural fact such as works_at, belongs_to, reports_to, or kinship
Journal Entry	Recorded evidence: interaction, observation, milestone, transaction, or commitment
Date Anchor	A recurring yearly date such as a birthday, anniversary, renewal, or memorial
Attribute	Flexible metadata and preference layer for contacts and links
Affinity Chart	Derived graph view of the active relationship network

The model means each kind of truth has its own home:

What it looks like	What it actually is
A person, company, team, service, or household	A Contact
An email address or handle	An Identity
A friendship or business relationship that changes over time	A Social Link
Employment, hierarchy, family, or membership	A Tie
“We talked yesterday”	A Journal entry
“I promised to send the recap”	A commitment-shaped Journal entry
“Their birthday is important every year”	A Date Anchor

State is derived, not hand-toggled. Rank, hidden Affinity, Trust movement, Moments, drift, readiness, and graph bridge significance are computed from evidence and explicit structural truth, not caller-written status flags.

Two Audiences

Human developers

Use the read and write namespaces for direct-code access to the domain:

import { read, write } from "@ghostpaw/affinity";

write.createContact(db, { name: "Ada", kind: "human" });
write.addIdentity(db, contactId, { type: "email", value: "[e-mail]" });
write.recordInteraction(db, {
  type: "support",
  occurredAt: now,
  summary: "Helped prepare for a difficult meeting",
  significance: 7,
  participants: [
    { contactId: ownerId, role: "actor", directionality: "mutual" },
    { contactId, role: "recipient", directionality: "mutual" },
  ],
});

const profile = read.getContactProfile(db, contactId);
const radar = read.listRadar(db);

See HUMAN.md for the full direct-code guide with modeling boundaries and worked examples.

LLM agents

Use the tools, skills, and soul namespaces for a structured runtime surface designed to minimize LLM cognitive load:

import { tools, skills, soul } from "@ghostpaw/affinity";

const allTools = tools.affinityTools;
const searchTool = tools.getAffinityToolByName("search_affinity")!;
const result = searchTool.handler(db, { query: "email:[e-mail]" });

const allSkills = skills.affinitySkills;
const prompt = soul.renderAffinitySoulPromptFoundation();

Every tool returns a discriminated result with outcome: "success" | "no_op" | "needs_clarification" | "error", structured entities, next-step hints, and actionable recovery signals.

See LLM.md for the full AI-facing guide covering soul, tools, and skills.

Tools

Twelve tools shaped around operator intent, not raw storage operations:

Tool	What it does
search_affinity	Search contacts by natural key or name
review_affinity	Dashboard-style list and graph review views
inspect_affinity_item	Open one exact profile or link detail
manage_contact	Create, revise, or change contact lifecycle
merge_contacts	Merge duplicate contacts safely
manage_duplicate_dismissal	Dismiss or restore a suspected duplicate pair
manage_identity	Add, revise, verify, or remove identities
manage_relationship	Seed social links, revise bond/state, manage structural ties
record_event	Record direct evidence, observations, milestones, or transactions
manage_commitment	Record or resolve obligations
manage_date_anchor	Add, revise, or remove recurring important dates
manage_attribute	Set, unset, or replace contact/link metadata

Each tool exports runtime metadata, JSON-Schema-compatible inputs, and structured outputs so harnesses can wire them without parsing vague prose.

Key Properties

• Zero runtime dependencies. Only node:sqlite (built into Node 24+).
• Single prebundled blob. One ESM + one CJS entry in dist/. No subpath exports, no code splitting.
• Pure SQLite storage. CHECK-constrained state, trigger-maintained support tables, and deterministic derived reads. Bring your own DatabaseSync.
• Derived mechanics. Rank, hidden Affinity, Trust, cadence, Moments, Radar, and bridge significance are computed from evidence and structure, never directly caller-set.
• Intention-shaped writes. createContact, setStructuralTie, recordInteraction, recordCommitment, addDateAnchor, mergeContacts: operations that say what happened or what truth changed, not generic CRUD.
• Additive AI runtime. soul for posture, tools for actions, skills for workflow guidance.
• Colocated tests. Every non-type module has a colocated .test.ts file. The documented behavior is backed by executable coverage.

Package Surface
