en-quire

en-quire is a skill for Claude Code, Codex from nullproof-studio/en-quire. It costs 115 tokens per session (5,469 once invoked), scanned A, original, MIT.

Instructions for using en-quire to read, search, edit, and manage Markdown and YAML documents. Markdown is a plain-text document format, while YAML is commonly used for structured configuration.

In plain words
What is it for?
Use it when managing notes, specifications, procedures, skill files, agent profiles, memory, or configuration files in Markdown or YAML.
Why use it?
It provides a consistent way to work with documents across multiple managed folders and helps track document status, indexing, and pending changes.

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

en-quire 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 3d 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.

Skill: en-quire — Markdown Document Management

Purpose: Instructions for agents using en-quire MCP tools to read, search, edit, and manage markdown and YAML documents.


Orientation: Multi-Root and doc_status

en-quire manages documents across multiple roots — separate directories for different document types (e.g. codex, agents, skills, testing). Each root can have its own git configuration and governance model.

Start every session with:

  1. doc_status — see all configured roots, their git status, index health, and pending proposals
  2. doc_list — see all files, or scope to a specific root with doc_list(scope: "skills")

File paths include the root prefix: codex/en-quire.mdx, agents/researcher.md, skills/en-quire/SKILL.md. Use the prefix in all tool calls.

Search works across all roots by default. Scope to a single root with doc_search(query: "...", scope: "agents").

When to Use en-quire

Use en-quire tools (doc_*) instead of filesystem tools (read_file, write_file, edit_file) for any operation on:

  • Markdown files (.md, .mdx) — SOPs, skill files, codex articles, session memory, agent profiles
  • YAML files (.yaml, .yml) — Docker Compose, config files, CI/CD pipelines, Kubernetes manifests

en-quire provides section-level addressing, structural search, and diff responses that eliminate the need to read or rewrite whole files. For YAML, "sections" are key paths (e.g. services.api.environment).

Use filesystem tools only when:

  • You are working with file types en-quire doesn't support (JSON, JS, etc.)
  • You need to move or copy files between directories or roots

Core Workflow: Outline → Read → Edit

Every interaction with a document follows this sequence:

  1. doc_outline — Get the structure first. This is non-negotiable. Never read a whole file to orient yourself. For markdown, this returns the heading tree. For YAML, it returns the key hierarchy with value types.
  2. doc_read_section — Read only the section you need. Use the heading text (markdown) or dot-path (YAML, e.g. services.api.environment). Take the address straight from the doc_outline result — a heading address must match the heading text exactly, including any trailing qualifier or parenthetical, so copy it rather than retyping from memory or from how the body prose refers to a section (e.g. "§13.1 Storage Mapping").
  3. Edit with the right tool:
    • doc_set_value — change a single value (YAML scalar or markdown section body). The simplest edit tool — one path, one value.
    • doc_replace_section — rewrite a block's content (mapping values in YAML, section body in markdown)
    • doc_append_section — add content to the end of a section (table rows, list items, new YAML keys)
    • doc_find_replace — change a term or phrase across the whole document
    • doc_insert_section — add a new section before or after an existing one
    • doc_delete_section — remove a section entirely
    • doc_move_section — atomically delete a section from its current location and insert it at a new position (cut-and-paste). Heading levels adjust automatically including all children. Use this instead of separate delete + insert calls.
    • doc_generate_toc — generate or update a table of contents from the heading structure

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.
