Identify the framework, language, package manager, database, and infrastructure. Read package.json, pyproject.toml, go.mod, Cargo.toml, pom.xml, or Gemfile for the full dependency list.
Find and read all route definitions. Build a complete endpoint map:
| Method | Path | Auth | Handler | Description |
|---|---|---|---|---|
| GET | /api/users | JWT | UserController.list | List users |
| POST | /api/users | JWT | UserController.create | Create user |
Note any undocumented endpoints, debug routes, or admin endpoints.
Identify the middleware execution order:
Note any middleware that applies globally vs. per-route.
List all database models/tables with:
Identify all external services the backend calls:
For each: note the client library used, timeout configuration, and circuit breaker status.

Format as:
## Backend Recon: [project name]
**Stack:** [language] + [framework] + [database]
**Routes:** [X] endpoints across [Y] resources
**Test coverage:** [estimated percentage or "none"]
### Route Map
[endpoint table from Step 1]
### Architecture
- **Auth:** [mechanism]
- **Middleware:** [stack summary]
- **Database:** [X] models, [Y] migrations
- **External deps:** [list with timeout/circuit breaker status]
### Code Quality
| Signal | Status | Notes |
|-------------------|---------------|------------------------------|
| Test coverage | Low/Med/High | [details] |
| Error handling | Consistent/Ad-hoc | [details] |
| Dependency health | Current/Stale | [X deps behind major versions] |
| Tech debt | Low/Med/High | [hotspot files] |
### Takeover Recommendations
1. [First thing to do when taking over this codebase]
2. [Second priority]
3. [Third priority]
Map for someone inheriting the project. Factual, specific, actionable.
If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
npx claudepluginhub tonone-ai/tonone --plugin eval-regressBackend reconnaissance — map all routes, middleware, models, dependencies, auth, and assess code quality for project takeover. Use when asked to "understand this backend", "map the API", or "assess code quality".
Reviews API and backend code for REST conventions, auth, validation, error handling, pagination, rate limiting, and test coverage.
System takeover — take ownership of an existing codebase or inherited system. Use when "we acquired this", "previous team left", "take over this system", "inherited this codebase".
