ase-meta-proximity is a skill for Claude Code from rse/ase. It costs 70 tokens per session (1,613 once invoked), scanned A, original, Apache-2.0.

A tool for mapping a topic's conceptual neighborhood: its broader parent, related sibling topics, and narrower child topics.

In plain words
What is it for?
Use it to explore a topic's parent, four relevant peers, and four more specific subtopics, with optional interactive navigation.
Why use it?
It helps organize an unfamiliar subject by showing where it sits among related ideas, optionally using current web information.

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.

Security

Grade A, and why

ase-meta-proximity 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 10d 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.

$ARGUMENTS

  1. REPEAT the following sub-steps in a LOOP until either is not equal true (then the loop runs exactly once and stops after rendering), or the user declines/cancels the dialog in sub-step 4:

    1. Determine Proximity:

      Set , to , and to to empty, so that a stale proximity of a previously navigated topic can never leak into the rendering below.

      Set .

      Determine the canonical name of the central topic and its conceptual proximity along the three dimensions PARENT (the single broader topic that is a specialization of), SIBLINGS (the four most relevant topics on the same level that share the same parent), and CHILDREN (the four most relevant narrower topics that are specializations of ) by using the ase-meta-proximity agent in a sub-agent with the following tool call:

      Agent( description: "Determine Conceptual Proximity", subagent_type: "ase:ase-meta-proximity", prompt: "<prompt/>", run_in_background: false )

      Parse the returned labeled list and set to the value of its TOPIC: line, to the value of its PARENT: line, to to the values of its four SIBLING: lines, and to to the values of its four CHILD: lines.

      Determine the canonical topic name, the parent, the siblings, and the children from model knowledge instead, and output the following :

    2. Render Proximity:

      Output the result with the following , listing each proximity topic under its bullet-prefixed section header.

      PARENT: ↑

      TOPIC: ○

      SIBLINGS: ⇄ ⇄ ⇄ ⇄

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.
