What is code-module-summaries?

A system for creating and maintaining Markdown summaries of code modules in any Git repository. It tracks each module from its last successfully summarized commit.

Use it to create, refresh, or selectively update module summaries and keep their Git-based update checkpoints organized.

It shows what changed since each module was last reviewed, without rescanning everything or relying on file timestamps.

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.

Model	Per session	Once invoked
Fable 5	$0.00041	$0.03343
Opus 5	$0.00020	$0.01672
Sonnet 5	$0.00008	$0.00669
Haiku 4.5	$0.00004	$0.00334

Security

Grade A, and why

code-module-summaries 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 yesterday.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/scan_changes.py, tests/test_scan_changes.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Code Module Summaries

Overview

Build and maintain evidence-backed Markdown summaries for an arbitrary Git repository. Treat each module's last successful commit SHA as its incremental checkpoint. Timestamps and Markdown mtimes are display metadata only.

The tracked control directory is the source of truth:

registry.json: stable module boundaries, layout, and summary paths.
state/<module-id>.json: one independent checkpoint per module.
modules/*.md: summaries when using the centralized layout.
INDEX.md: links and module ownership; update only when mappings change.

Invocation

Interpret user arguments with this contract:

/code-module-summaries [repo]
  [--output <control-dir>]
  [--layout centralized|colocated|custom]
  [--update]
  [--module <id-or-exact-name>]...
  [--target <git-ref>]
  [--refresh-modules]
  [--summary-name <filename.md>]
  [--head-only]
  [--accept-summary-drift]
  [--adopt-existing-summary]
  [--rebaseline --reason <text>]

Defaults:

repo: current Git root.
--output: code-summaries/.
--layout: centralized.
--target: the registry's tracked_ref, normally HEAD.
--summary-name: MODULE_SUMMARY.md for colocated summaries.

--layout custom places each module's Markdown at an arbitrary in-repository .md path declared per module in registry.json (summary_path), with no fixed directory shape. This is the layout for a shared conclusions/-style tree, for example enterprise/conclusions/apps/gateway_conclusion.md. A custom registry may also declare a top-level index_path (e.g. enterprise/conclusions/README.md): a managed overview file the agent maintains, excluded from module source diffs and unassigned-path checks. See REFERENCE.md §9 for exact rules. centralized and colocated are unchanged.

--module is repeatable and case-sensitive. It selects exact IDs first, then an exact unique name. Never use fuzzy matching for a write operation.

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
