rule-manager

rule-manager is a skill for Claude Code from aigentive/RalphX. It costs 70 tokens per session (774 once invoked), scanned A, original, Apache-2.0.

A tool that reviews .claude/rules/ files and applies one token-saving improvement at a time. It also records each change in a memory log.

In plain words
What is it for?
Use it to audit rule files, find issues such as excessive size or missing path scope, inspect prior optimization logs, and apply the highest-priority single improvement.
Why use it?
It helps keep the rules that guide an agent concise and focused, so they use less context and remain easier to maintain. The input does not specify the exact optimization chosen in each run.

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

rule-manager 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 1mo ago.

The scan reads SKILL.md. This mod also ships 10 executable files (scripts/lib/common.sh, scripts/rule-apply-paths.sh, scripts/rule-audit.sh, …), 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.

Rule Manager

Iteratively optimizes .claude/rules/ for token efficiency. Each run: audit -> pick ONE optimization -> apply -> log.

Step 1: Read Framework Reference

Read the memory framework doc for context on priorities and standards: ${CLAUDE_PLUGIN_ROOT}/memory-framework.md

Also fetch/refresh the official Claude Code memory docs (cached locally):

"${CLAUDE_PLUGIN_ROOT}/skills/rule-manager/scripts/rule-fetch-docs.sh"

Step 2: Audit

Run the audit script to collect current state:

"${CLAUDE_PLUGIN_ROOT}/skills/rule-manager/scripts/rule-audit.sh" --json

Parse the JSON output. Report to user:

  • Total files, lines, estimated tokens
  • Files with/without paths: frontmatter
  • Files with @ references
  • Health indicators (oversized, unscoped, refs)

Also read the optimization log to see what's been done (per-day files): .claude/memory/ (read the latest file, or all files for full history)

Step 3: Identify ONE Optimization

Pick the HIGHEST priority that applies (do NOT do multiple):

Priority 1: @ References Between Rules

If any rule file has @ references to other rule files:

"${CLAUDE_PLUGIN_ROOT}/skills/rule-manager/scripts/rule-strip-refs.sh" <filename> --dry-run

Show the preview to user. If approved:

"${CLAUDE_PLUGIN_ROOT}/skills/rule-manager/scripts/rule-strip-refs.sh" <filename>

Priority 2: Unscoped Domain Rule

If a rule lacks paths: frontmatter but is domain-specific:

"${CLAUDE_PLUGIN_ROOT}/skills/rule-manager/scripts/rule-suggest-paths.sh" <filename>

Review the suggestions. For complex cases, use an Explore agent to grep the codebase for the rule's key terms. Show proposal to user. If approved:

"${CLAUDE_PLUGIN_ROOT}/skills/rule-manager/scripts/rule-apply-paths.sh" <filename> "pattern1" "pattern2"

Priority 3: Oversized Rule (>400 LOC)

If a rule exceeds 400 lines:

  • Read the file and identify distinct sections
  • Propose splitting into 2-3 focused files with paths: frontmatter
  • Create new files, delete original
  • This is a manual operation (no script -- requires judgment)

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.

rule-manager is a skill published in the GitHub repository aigentive/RalphX (5 stars, last pushed 24d ago), licensed Apache-2.0. It adds 70 tokens to every session and 774 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-08-31.
