Root Cause AnalysisProblem Being Solved: Creating a comprehensive competitive deep-dive document comparing codegraph against narsil-mcp, following the same structure as the competitive analysis framework. This serves to position codegraph clearly against its closest head-to-head competitor. Why This Approach: The document follows the established template from the competitive analysis ranking system where narsil-mcp is ranked #2 (tied with Joern at 4.5 points). Unlike other competitors that target different audiences, narsil-mcp directly competes with codegraph on the same dimensions (tree-sitter, MCP, AI agents, local-first). Risk Assessment: This is a documentation-only PR with no code changes. The risk is minimal—primarily around factual accuracy and positioning claims. Document Structure and Quality Assessment✅ Follows Established TemplateThe document perfectly mirrors the COMPETITIVE_ANALYSIS.md structure:
✅ Comprehensive Feature CoverageThe analysis covers 130+ features across 9 well-organized sections:
✅ Balanced and Fair AnalysisThe document presents a balanced view:

| | 7 | **Security-conscious defaults** — multi-repo opt-in | Single-repo MCP default. `apiKeyCommand` for secrets. `--multi-repo` opt-in | Multi-repo by default (`list_repos`, `discover_repos` always exposed). `--remote` flag enables cloning external repos. No credential isolation model | **Codegraph wins.** Single-repo default vs. multi-repo default. narsil-mcp's `discover_repos` and `add_remote_repo` tools are exposed without opt-in | | ||

Not an app, not a coding tool, not an agent | "Comprehensive code intelligence" — tries to be everything: search engine, security scanner, type checker, SBOM generator, license auditor, knowledge graph, visualization server | **Codegraph wins.** Codegraph has a clear boundary. narsil-mcp's 90-tool surface area spans security, compliance, visualization, type checking, and more — a breadth that risks being shallow everywhere | | ||

| **Score: Codegraph 6, narsil-mcp 0, Tie 2** — against codegraph's own principles, codegraph wins on every differentiating dimension. This is expected: the principles were designed around codegraph's value proposition. The feature comparison below examines where narsil-mcp's breadth creates genuine advantages. |

Math error in scoring. The table above shows 7 Codegraph wins, 0 narsil-mcp wins, and 1 Tie (Principle 2). Should be "Codegraph 7, narsil-mcp 0, Tie 1" not "Codegraph 6, narsil-mcp 0, Tie 2".

Same math error repeated. Should be "Codegraph 7, narsil-mcp 0, Tie 1" to match the actual table counts from the Problem Alignment section.

| **Context:** narsil-mcp is ranked #2 in our [competitive analysis](./COMPETITIVE_ANALYSIS.md) with a score of 4.5, tied with Joern at #1. Unlike Joern (which targets security researchers), narsil-mcp competes head-to-head with codegraph — same parsing technology (tree-sitter), same delivery mechanism (MCP), same target audience (AI agents), same local-first philosophy. |

Incorrect relative path. This file is in generated/competitive/ and COMPETITIVE_ANALYSIS.md is in generated/, so the link should use ../ not ./

Fixed in 2d599b5 — changed ./COMPETITIVE_ANALYSIS.md to ../COMPETITIVE_ANALYSIS.md since this file lives in the generated/competitive/ subdirectory.
- Fix principle scoring from 6-0-2 to 7-0-1 (correct count from table) - Fix relative link to COMPETITIVE_ANALYSIS.md (../ not ./)
