Context Map

Context Map

Generate a compressed context map for the current project. The map pre-compiles structural knowledge that AI assistants would otherwise discover through expensive Read/Grep calls, saving thousands of tokens per session.

When to Use

• At the start of a session to understand project layout
• Before implementing features to identify entry points
• When exploring an unfamiliar codebase
• To reduce token waste from Read calls
• To identify hot files (high blast radius) before changes

What It Detects

Procedure

1. Run the scanner on the project root:

PYTHONPATH="$(find . -path '*/conserve/scripts' -type d \
  -print -quit 2>/dev/null || \
  echo 'plugins/conserve/scripts')" \
  python3 -m context_scanner .

2. Present the output to the user as the project overview.

3. Use the context map to guide subsequent file reads. Prioritize hot files and entry points first.

Options

Output

• --format json for structured output
• --max-tokens N to adjust output size (default: 5000)
• --output FILE to save to a file

Modes

• --blast FILE to show blast radius for a specific file
• --section NAME to output a single section

(routes, deps, env, hot-files, models, structure, middleware, frameworks)

• --wiki-only to generate wiki articles without stdout

Opt-out

• --no-cache to force a fresh scan
• --no-wiki to skip wiki article generation

Wiki Articles

The scanner generates per-topic knowledge articles in .codesight/ for selective context loading:

python3 scanner.py .
# Creates .codesight/INDEX.md, auth.md, database.md, etc.

Load only what you need per session instead of the full map:

python3 scanner.py --section routes .
# ~200 tokens vs ~5,000 for the full map

Example Output

# Context Map: myproject
Files: 127

## Structure
  src                  42 files (Python)
  tests                18 files (Python)
  docs                  5 files (Markdown)

## Dependencies (Python)
Package manager: uv
  - fastapi 0.104.0
  - pydantic 2.5.0
  - sqlalchemy 2.0.0
  ...12 more

## Frameworks Detected
  - FastAPI
  - SQLAlchemy
  - Pytest

## Routes
  GET    /users          (src/routes/users.py)
  POST   /users          (src/routes/users.py)
  GET    /users/{id}     (src/routes/users.py)

## Hot Files (high blast radius)
  - src/models/base.py (12 importers)
  - src/utils/auth.py (8 importers)

## Environment Variables
  - DATABASE_URL (required)
  - SECRET_KEY (has default)

## Token Savings: ~12,600 tokens saved
  Routes: ~1,200
  Hot files: ~300
  Env vars: ~200
  File scanning: ~10,200

Exit Criteria

• [ ] Scanner produces output covering at minimum: file count,

directory structure, detected frameworks, and hot files (imported by 3+ others); output appears in the session before any feature implementation reads begin

• [ ] "Token Savings" line is present in the output with a numeric

estimate (e.g., ~12,600 tokens saved)

• [ ] If --blast FILE is used, blast-radius output names the

specific file and lists its importers by count

• [ ] Context map guides subsequent reads: hot files and entry points

are consulted before any other file read in the session
