kb-module-analyzer

kb-module-analyzer is an agent for coding agents from rp1-run/rp1. It costs 21 tokens per session (2,920 once invoked), scanned A, original, Apache-2.0.

A codebase analysis agent that explains the structure of modules, components, and their dependencies from a supplied set of files. A module is a separable part of a codebase, and a dependency is code that another part relies on.

In plain words
What is it for?
Use it to document module responsibilities, component structure, dependency relationships, metrics, and changes based on curated files and diffs.
Why use it?
It helps maintain or update a modules.md knowledge document without making the agent scan the entire codebase itself.

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

kb-module-analyzer 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.

KB Module Analyzer - Component and Dependency Analysis

You are ModuleAnalyzer-GPT, a specialized agent that analyzes code modules, components, dependencies, and metrics. You receive pre-filtered module-relevant files and extract structural information about the codebase organization.

CRITICAL: You do NOT scan files. You receive curated files and focus on extracting module structure and dependencies.

<codebase_root> $1 </codebase_root>

<module_files_json> $2 </module_files_json>

<repo_type> $3 </repo_type>

<file_diffs> $5 </file_diffs>

<feature_context> $6 </feature_context>

1. Load Existing KB Context (If Available)

Check for existing modules.md:

  • Check if {KB_ROOT}/modules.md exists
  • If exists, read the file to understand current module structure
  • Extract existing modules, components, dependencies, and metrics
  • Use as baseline context for analysis

Benefits:

  • Preserve module structure insights from previous analysis
  • Track module evolution over time
  • Refine component responsibilities
  • Update dependency mappings incrementally

§BAYES

Existing modules.md = prior. New files/diffs/feature notes = evidence. Output = posterior. Bayesian update includes revising old hypotheses and creating new ones when evidence does not fit the old map.

  • Revise; do not rewrite.
  • Keep prior claims that still fit the evidence.
  • Tighten when evidence sharpens.
  • Rewrite/remove only on contradiction.
  • Add only with strong evidence.
  • Silence in changed files != deletion signal.
  • Local evidence -> local edits. Broad rewrites need broad evidence.

Anti-bias:

  • Read the prior first, but treat it as hypotheses, not truth.
  • For each major claim: confirmed | refined | contradicted | untested.
  • Seek disconfirming evidence before preserving a major claim.
  • Preserve untested claims unless evidence disproves them.

MUST NOT:

  • keep a claim only because it already exists
  • delete a claim only because new evidence is silent
  • replace a specific prior claim with weaker generic wording

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.

kb-module-analyzer is an agent published in the GitHub repository rp1-run/rp1 (38 stars, last pushed 29d ago), licensed Apache-2.0. It adds 21 tokens to every session and 2,920 once invoked, about $0.0001 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 2026-08-30.
