sdlc-navigate

sdlc-navigate is a command for coding agents from saitarrun/Devforge-ai. It costs 23 tokens per session (466 once invoked), scanned A, original, Apache-2.0.

A codebase exploration command for mapping folders, symbols, dependencies, and call chains. A monorepo is one repository containing multiple projects or services.

In plain words
What is it for?
Use it to trace callers and callees, inspect module boundaries, find circular dependencies, map data flow, and summarize system architecture.
Why use it?
It helps developers understand unfamiliar large codebases and see what may be affected before changing a function or module.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sdlc-navigate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Codebase Map & Navigation Command

This command enables rapid structural exploration and architectural understanding of large codebases, monorepos, and multi-service repositories.

Usage

/sdlc-navigate "AuthService"            # Trace callers, callees, and dependencies
/sdlc-navigate src/billing/ --deep      # Map module boundaries and coupling
/sdlc-navigate "processPayment" --impact # Show what breaks if this function is modified
/sdlc-navigate "architecture"           # High-level domain topology & service map

Process

  1. Load Structural Knowledge Graph:
    • Query code-review-graph (or AST analyzer) for symbol relationships, call hierarchies, and coupling metrics.
  2. Trace Ingress to Egress:
    • Map entrypoint controllers/routes down to service abstractions, database queries, and emitted events.
  3. Analyze Module Boundaries:
    • Identify circular dependencies, layered architecture violations, and shared package imports.
  4. Synthesize Clean Visual Map:
    • Produce a concise summary of symbols, caller chains, data flows, and architectural constraints.

Output Format

### 🗺️ Codebase Map: [Target Symbol / Module]

**Domain Context**: [Service/Package responsible for this logic]
**Location**: `path/to/definition.ts`

#### 🔗 Dependency & Call Chain
- **Ingress Entrypoints**:
  - `GET /api/v1/resource` -> `Controller.handleRequest()`
- **Core Orchestrator**:
  - `Service.executeBusinessLogic()`
- **Persistence & Egress**:
  - `Repository.save()` -> PostgreSQL Table: `resources`
  - Event Bus: Emits `ResourceCreatedEvent` -> Kafka Topic: `events.resource`

#### ⚠️ Impact & Coupling Analysis
- **Direct Consumers**: 4 services / 12 callers
- **Risk Level**: Low / Moderate / High (Shared Public API)

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
