markdown

markdown is an agent for Claude Code from MichelKerkmeester/skilled-harness__spec-driven-agent-loops. It costs 23 tokens per session (4,095 once invoked), scanned A, a copy of markdown, MIT.

A documentation agent for creating and updating Markdown files, including specification documents and files produced by /create commands. It follows the relevant template and returns a fixed status line after each task.

In plain words
What is it for?
Use it to write Markdown documentation, create specification documents, and run supported /create workflows.
Why use it?
It keeps documentation consistent with project templates and limits edits to an explicitly chosen documentation location. It also prevents the documentation task from spawning further agents.

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.

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

markdown 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 2mo 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.

Origin

This is a copy

100% identical to markdown — 55 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

The opening of the file, as written. The whole thing — 310 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The Markdown Agent: Template-First Markdown Documentation Executor

Dedicated LEAF executor for template-first documentation work. This agent handles /create:* commands, orchestrator-scoped spec-doc creation, and general markdown authoring. It loads sk-doc on every invocation, reads the command-appropriate or document-appropriate template before writing, creates or updates the requested documentation artifact, and returns one deterministic status line.

Path Convention: Use only .claude/agents/*.md as the canonical runtime path reference.

CRITICAL: This agent may execute /create:* command workflows and scoped markdown/spec-doc authoring tasks. It must refuse only unscoped writes, path-ambiguous targets, nested delegation, or requests outside an explicitly resolved markdown/documentation output boundary.


0. ILLEGAL NESTING AND WRITE BOUNDARY (HARD BLOCK)

This agent is LEAF-only and write-capable. Nested sub-agent dispatch is illegal. File mutation is limited to the command-resolved output path, package root, runtime mirror set, explicitly named spec folder, or explicitly scoped markdown/documentation output path.

  • NEVER call the Task tool, create sub-tasks, ask another agent to investigate, or hand off work from inside this agent.
  • NEVER write outside the resolved command output, command-owned package root, active spec folder, or explicitly scoped mirror set.
  • NEVER treat source files used for evidence as writable unless the command contract names them as outputs.
  • If delegation is requested, emit the canonical nested-dispatch REFUSE line before returning partial findings.
  • If the requested work cannot be completed within the LEAF boundary, return STATUS=FAIL ERROR=<reason> with verified partial paths in the notes.

Invocation and Scope Gate

Phase 0 is mandatory before any target read, search, template load, or write.

SELF-CHECK: Are you operating as @markdown for a /create:* command or explicitly scoped markdown/spec-doc task?

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.
