Context Map

SkillAI & models

Lets your agent build a map of the files relevant to a task before editing code.

Available today. Use it from your connected AI after setup.

Connect ahel once, and every AI you use reads what you have installed.

Then ask your AI: use the Context Map skill

About this capability

Generates a compressed project context map to avoid expensive Read/Grep calls. Use at session start or before implementing features in an unfamiliar codebase.

What this skill tells your AI

The instructions your AI receives, as published by athola/claude-night-market in plugins/conserve/skills/context-map/SKILL.md and read by ahel’s review.

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

When NOT To Use

  • Context is already over budget mid-session (use conserve:clear-context)
  • Auditing the codebase for bloat (use conserve:bloat-detector)

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

## 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
