index-rebuild

index-rebuild is a skill for Claude Code from MacroMan5/macromanatlas. It costs 33 tokens per session (721 once invoked), scanned A, original, MIT.

A command that rebuilds a project's searchable index, either for the whole project or for one module. A module is a distinct part of a larger codebase.

In plain words
What is it for?
For rebuilding every module, updating the index for a named module, or supplying custom instructions about what to emphasize.
Why use it?
It keeps project documentation and search information aligned with the current code, while allowing a focused rebuild when only one part changed.

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

index-rebuild 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 11d 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.

How it starts

The opening of the file, as written. The whole thing — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/index-rebuild

Rebuild the project index, optionally targeting a specific module with custom instructions.

Usage

/index-rebuild                              Full rebuild (all modules + index)
/index-rebuild --module MacroMan-Tracking   Rebuild only Tracking README + update index
/index-rebuild --module MacroMan-Tracking --m "Focus on TrackState machine transitions"

Step 1: Parse arguments

Parse $ARGUMENTS for:

  • --module <name> — target a specific module (optional)
  • --m "<instructions>" or --m <instructions> — custom emphasis instructions (optional)

If no arguments: full rebuild of all modules.

Step 2: Announce

If --module specified: Say: "Rebuilding index for module: " If full rebuild: Say: "Rebuilding complete project index..."

Step 3a: Targeted rebuild (--module specified)

  1. Verify the module directory exists. If not, list available modules and ask user to pick one.
  2. Scan the module:
    • List files with git ls-files <module>/ (or Glob fallback)
    • Read interface/header/export files for public API
    • Extract dependencies from build files (CMakeLists.txt, package.json, Cargo.toml, etc.)
    • Generate tags from file names, class names, function names
  3. Read existing <Module>/README.md
  4. Preserve the <!-- CUSTOM --> section content
  5. Regenerate the <!-- AUTO-GENERATED --> section using the same template as /index-init Step 3
  6. If --m instructions provided:
    • Use them to guide emphasis in the README generation (what classes to detail, what patterns to document)
    • Save the instructions in the CUSTOM section as: **Index instructions**: <instructions>
  7. Write the updated README
  8. Update .claude/index.md:
    • Update the module's row in the Modules table
    • Update the Tag Index for this module's tags only
  9. Regenerate .claude/index.summary.md from .claude/index.md (keep under 4KB)

Step 3b: Full rebuild (no --module flag)

Perform the same steps as /index-init Steps 2-4, but:

  • PRESERVE all <!-- CUSTOM --> sections in existing READMEs
  • PRESERVE the <!-- CUSTOM --> section in .claude/index.md
  • Do NOT re-add the CLAUDE.md section if it already exists (look for "Code Navigation" or "Code Index")
  • Do NOT modify hooks (they're managed by the plugin)
  • Regenerate the "How to Use" section in .claude/index.md with the navigation strategy (tags → README → targeted grep)
