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

CategoryDescription
StructureDirectory layout with file counts and languages
DependenciesMulti-ecosystem: Python, Node, Rust, Go, Java
FrameworksFramework detection from dependency analysis
Entry Pointsmain.py, index.ts, CLI scripts, etc.
Import GraphFile-to-file import relationships
Hot FilesFiles imported by 3+ others (high blast radius)
RoutesFastAPI, Flask, Express, Hono API endpoints
Env VarsEnvironment variable references with defaults
MiddlewareAuth, CORS, rate-limit, logging patterns
Models/SchemasSQLAlchemy, Django, Pydantic, Prisma definitions
Token SavingsEstimated tokens saved vs manual exploration

Procedure

  1. Run the scanner on the project root:
python3 "$(find . -path '*/conserve/scripts/context_scanner.py' \
  -print -quit 2>/dev/null || \
  echo 'plugins/conserve/scripts/context_scanner.py')" .
  1. Present the output to the user as the project overview.

  2. 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
