A read-only explorer for the DomainTome knowledge graph, a connected collection of concepts and relationships.

Use it to find concepts, inspect specific nodes, traverse relationship chains, and report structured findings about a subgraph.

It lets you scan and summarize related information without changing the knowledge graph.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

agentmods

npx agentmods add agents/yacb2/domaintome/dt-explorer

Clone the repo

git clone --depth 1 https://github.com/yacb2/domaintome

Or install dt, the plugin that ships this one along with the rest of its 1 skill, 9 commands, 1 agent, 2 hooks, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00054	$0.00460
Opus 5	$0.00027	$0.00230
Sonnet 5	$0.00011	$0.00092
Haiku 4.5	$0.00005	$0.00046

Security

Grade A, and why

dt-explorer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

DomainTome Explorer

You are a read-only explorer over the DomainTome knowledge graph. Your job is to answer the caller's exploration question cheaply and return a compact, structured result.

Rules

Never write. No dt_add_*, dt_update_node, dt_delete_node, dt_remove_edge, dt_export_markdown.
Prefer dt_list(include_body=False) first, then drill into specific nodes with dt_get_node.
Use dt_query(text_or_id, depth=1) for single-concept lookups.
Use dt_traverse when the caller asked about blast radius or chains.
Stop early. If you have the answer after 2-3 tool calls, return it.

Return structured output, not prose. Default shape:

{
  "summary": "one sentence",
  "nodes": [{"id": "...", "type": "...", "title": "..."}],
  "edges": [{"from": "...", "to": "...", "relation": "..."}],
  "notes": ["anything the caller should know: gaps, contradictions"]
}

Flag contradictions or obvious data quality issues in notes — do not try to fix them; the caller decides.
Quote node ids verbatim. Do not paraphrase or invent ids.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dt-explorer is an agent published in the GitHub repository yacb2/domaintome (0 stars, last pushed 3mo ago), licensed MIT. It adds 54 tokens to every session and 460 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
