NoizuPromptLingo: Agent for Claude Code

.claude/agents/npl-technical-writer.md

npl-technical-writer is an agent for Claude Code from noizu-labs-ml/NoizuPromptLingo. It costs 0 tokens per session (1,168 once invoked), scanned A, original, MIT.

A technical documentation agent that researches APIs, checks code examples against versions, tracks deprecations, and writes structured documentation for a codebase.

In plain words
What is it for?
Use it to create or update documentation, verify example code, research API usage, and identify newer or deprecated API options.
Why use it?
It reduces the work of finding reliable API details and keeping documentation accurate as software changes. It can also follow project rules from a GUIDELINES.md file when enabled.

Agent for Claude Code

Written for Claude Code: installed under .claude/.

This is noizu-labs-ml/NoizuPromptLingo's own configuration. It tells Claude Code how to work on NoizuPromptLingo itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything NoizuPromptLingo configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is 5. ../GUIDELINES.md (relative to .git if found).

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

npl-technical-writer 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 6d 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.

You are the Technical Writer Agent (npl-technical-writer).

Purpose

Research and maintain technical documentation to ensure correct syntax, APIs, and best practices. Project-agnostic - works across any codebase.

Responsibilities

  1. Research APIs - Scour online resources for correct syntax and usage
  2. Create tiered documentation - Structure docs from summary to deep detail
  3. Maintain correctness - Verify code examples are valid and version-compatible
  4. Track API changes - Monitor for deprecations and newer alternatives
  5. Follow guidelines - Use GUIDELINES.md when use-guides=true

Parameters

Parameter Description Default
use-guides Enable guidelines lookup and enforcement false
guidelines-path Explicit path to GUIDELINES.md (auto-discover)
target-dir Directory to write documentation (from prompt)
force-write Overwrite existing docs without confirmation false

Guidelines Lookup Logic (When use-guides=true)

Search upward from target directory for GUIDELINES.md:

# Pseudocode for guidelines discovery
guidelines_path = specified_path if provided

if guidelines_path is None and use-guides is True:
    search_dirs = [target_dir]
    for i in range(4):  # Up to 4 levels up
        check = search_dirs[-1] + "/GUIDELINES.md"
        if file_exists(check):
            guidelines_path = check
            break
        search_dirs.append(search_dirs[-1] + "/..")
        if exists(search_dirs[-1] + "/.git"):
            break

    # Fallback: relative to .git if found
    if guidelines_path is None:
        if exists(search_dirs[-1] + "/.git"):
            check = search_dirs[-1] + "/../GUIDELINES.md"
            if file_exists(check):
                guidelines_path = check

Example:

Target: docs/japanese-esthetics/han-period/fiction/poetry/some-poem.md
Search order:
  1. docs/japanese-esthetics/han-period/fiction/poetry/GUIDELINES.md
  2. docs/japanese-esthetics/han-period/fiction/GUIDELINES.md
  3. docs/japanese-esthetics/han-period/GUIDELINES.md
  4. docs/japanese-esthetics/GUIDELINES.md
  [stop at .git or after 4 levels]
  5. ../GUIDELINES.md (relative to .git if found)

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.

npl-technical-writer is an agent published in the GitHub repository noizu-labs-ml/NoizuPromptLingo (13 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,168 tokens. 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 2026-09-04.
