ref-ingestThe single entry point for incoming information of ANY kind about a reference entity (a person, org, product, engagement, or watched competitor).
Ref Ingest is an agent skill from Abilityai/cornelius. The single entry point for incoming information of ANY kind about a reference entity (a person, org, product, engagement, or watched competitor). Extracts entity facts, RESOLVES them to the one existing canonical note (never duplicating), reconciles new-vs-old, and upserts (overwrite body, re-stamp asof, append Change Log), then reindexes. Extends manage-reference-data with entity resolution + reconciliation + the market-vs-CRM automation split. Company is the default scope. NEVER writes any provenance but…
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Business, Finance & HR, covering Accounting and bookkeeping. The repository describes itself as: AI-powered second brain template for Claude Code + Obsidian. The licence is MIT.
7 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit fd5e9a4. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadWriteEditBashGlobGrepAskUserQuestionSkillFrom allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
pythonFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Ref Ingest loads about 2.4k tokens when it runs. Until then it costs about 152 tokens; SKILL.md has 891 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, Write, Edit, Bash, Glob, Grep, AskUserQuestion, SkillAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/ref-ingest/SKILL.md (or your agent's skills folder).ℹ️ First, set expectations: before anything else, print one short line with this skill's version and its most recent change — the top entry of
metadata.changelogabove — e.g.ref-ingest v1.0 — recent: initial version. Then proceed.
The one operation every input funnels through for a reference scope: incoming info → resolve → reconcile → upsert. It grows the manual single-upsert manage-reference-data with the two load-bearing hard parts — entity resolution (is this new "Reply" the existing Reply.io?) and reconciliation (new fact contradicts old → overwrite / supersede-with-history / flag) — plus the automation split by scope.
Read first (authoritative — this skill enforces, does not restate):
resources/layered-brains/COMPANY-BRAIN-SCHEMA.md → "The update model", "The two axes" (sub-scope routing + type:/relationship: enums), "Automation boundary — split by scope".resources/layered-brains/REFERENCE-SCOPE-SCHEMA.md → the reference-kind frontmatter contract..claude/skills/manage-reference-data/SKILL.md → the seed upsert (Step 0 scope check + the frontmatter template). This skill is its richer successor; it does not duplicate the contract./ref-supersede — when reconciliation finds a validity transition that needs a prior snapshot (contract renewal, role/price change), hand off instead of overwriting. Never invoked on the market/autonomous branch (see the invariant).| Source | Location | Read | Write | Description |
|---|---|---|---|---|
| Company family | Brain/Company/{people,orgs,products,engagements,market}/*.md | ✓ | ✓ | Entity notes (one note = one entity) |
| Scope registry | resources/local-brain-search/memory_config.py | ✓ | Confirm reference-kind | |
| LBS index | resources/local-brain-search/data/ | ✓ | ✓ (reindex) | FAISS + graph; reindexed after a write |
| Search wrappers | resources/local-brain-search/run_search.sh | ✓ | Entity-resolution search under a core,Company mount |
| Sub-scope | Writer | This skill |
|---|---|---|
market/ (watched competitors/ecosystem) | autonomous | auto-overwrite, no gate — reference facts sit outside the encountered→endorsed gate |
people/ orgs/ products/ engagements/ (transacted CRM) | curated | human-gated — present the diff, get approval before writing |
Invariant (what makes any autonomous caller safe): the market/ branch is overwrite-only — it never opens an approval gate and never calls /ref-supersede. A validity transition in market/ that would need a snapshot is flagged for a human ref-supersede, not auto-run. So a scheduled caller (e.g. ref-refresh, or domain-watch in 9e) that routes market items here always takes a gate-free path.
cd resources/local-brain-search
SCOPE="${scope:-Company}"
./venv/bin/python - "$SCOPE" <<'PY'
import sys, memory_config as mc
f = sys.argv[1]
print("kind:", mc.scope_kind(f), "| is_reference:", mc.is_reference_scope(f))
PYIf is_reference is False → stop (this skill only writes reference scopes). See the schema doc's "Adding a new reference scope".
From the incoming info (the user in conversation · a document/contract/deck/call · a domain-watch market signal · another agent's report), pull the atomic facts about one real-world entity: display name + aliases, type:, the relation to us (relationship:), body facts, and any term-bearing fact (a contract window, a role start, a price effective date).
Apply the partition rule from COMPANY-BRAIN-SCHEMA "The two axes":
market/people/ orgs/ products/ engagements/ by type:. The internal agent workforce (type: agent) lives in products/ alongside own products — there is no separate agents/ sub-scope.type:/relationship: values MUST come from the schema doc's enum (person·organization·product·agent·engagement·interaction × the relationship axis). Never invent a value.Find the one canonical note this fact belongs to before writing:
# semantic: does an entity like this already exist in the family?
BRAIN_READ_SCOPE=core,Company resources/local-brain-search/run_search.sh "<entity name + a distinctive fact>" --limit 8 --json
# exact/alias: title + body match
grep -rilE "<name>|<alias1>|<alias2>" Brain/Company/AskUserQuestion); do NOT guess a new note into existence.Compare the incoming fact to the note's current body:
| Situation | Action |
|---|---|
| New fact corrects/refreshes an existing fact (same validity window) | overwrite the body (Step 6) |
| A validity window closed and a full prior snapshot matters (contract renewed, role changed, price re-termed) | hand to /ref-supersede — CRM only; on market/ flag for a human instead |
| New fact contradicts old with no clear winner | flag — surface both, ask; do not silently overwrite |
market/ → proceed (no gate). CRM sub-scopes → show the before/after diff and get explicit approval (AskUserQuestion) before writing.manage-reference-data Step 2 — do not restate it here). On update: overwrite the body (current truth), preserve created/created_by, re-stamp as_of + updated to today, bump updated_by to your model. Append a ## Change Log line:## Change Log

The single entry point for incoming information of ANY kind about a reference entity (a person, org, product, engagement, or watched competitor). Ref Ingest is an agent skill from Abilityai/cornelius. The single entry point for incoming information of ANY kind about a reference entity (a person, org, product, engagement, or watched competitor).
Ref Ingest fits situations like: tasks that involve Accounting and bookkeeping.
Run `npx skills add Abilityai/cornelius --skill ref-ingest -a claude-code`. Or copy the skill folder (.claude/skills/ref-ingest in Abilityai/cornelius) into .claude/skills/ref-ingest in your project. Claude Code loads it when a task matches its description.
Run `npx skills add Abilityai/cornelius --skill ref-ingest -a codex`. Or copy the skill folder (.claude/skills/ref-ingest in Abilityai/cornelius) into .agents/skills/ref-ingest in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Abilityai/cornelius --skill ref-ingest -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/ref-ingest, .gemini/skills/ref-ingest, .github/skills/ref-ingest and .opencode/skills/ref-ingest in your project.
Going by SKILL.md and its folder, Ref Ingest needs the command-line tools its instructions call (python). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Write, Edit, Bash, Glob, Grep, AskUserQuestion, Skill.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Ref Ingest is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.4k tokens (SKILL.md is roughly 9.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Ref Ingest: Sync Upstream (nyaruka/phonenumbers, 1.6k stars), Longbridge Value Investing (helsome/folio, 269 stars), Radiology Table (huang-sir1/radiology-skills, 1.9k stars) and Odoo Agency Fleet Review (erpipe-org/mcp-odoo, 420 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
