Smart Context Pack

When the user runs /cco-pack or asks "what files do I need for X", build a curated, token-budget-aware list of files to load instead of guessing or reading the whole repo.

How to use

node ${CLAUDE_PLUGIN_ROOT}/src/smart-pack.js "the task description"

Or for the current git state without a description:

node ${CLAUDE_PLUGIN_ROOT}/src/smart-pack.js

Or to feed it back into automation as JSON:

node ${CLAUDE_PLUGIN_ROOT}/src/smart-pack.js --json "..."

How it ranks files

Priority order:

1. Mentioned in prompt — explicit file paths or recognisable names → relevance 100
2. Modified in git working tree → 85
3. Historically useful in this project (high confidence, edited often) → up to 70
4. Keyword match against the task → up to 70

For each file the pack also suggests offset / limit — pointing at the structurally relevant section based on file landmarks (function/class declarations near task keywords).

Token budget awareness

Pack stops adding files once it would exceed 25% of the user's effective context budget. The budget itself respects the configured model (e.g. the full 1M window for opus-5.5 — 1M is standard on Opus, no premium tier).

Presentation

After running, present the list to the user and offer to:

• Read the top N files with the suggested offset/limit
• Save the set as a template (/cco-templates create <name>)
• Drop low-relevance items if they want a tighter pack
