Code Review

A code-review guide for changes in the dotcontext CLI project. It checks code quality, design patterns, project conventions, and best practices against that project’s TypeScript structure.

In plain words
What is it for?
Use it when reviewing a pull request, validating work, or checking new TypeScript services, generators, utilities, and MCP gateway handlers in the dotcontext project.
Why use it?
It helps reviewers spot code that conflicts with existing architecture or standards before it is merged. It also provides a consistent way to assess pull requests and changes to services, generators, utilities, and gateway handlers.

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

Code Review 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 2d 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.

Code Review

Guidelines for reviewing code changes in the @dotcontext/cli project.

When to Use

  • Reviewing a pull request or diff
  • Validating code during the Review (R) or Validation (V) phases of the PREVC workflow
  • Checking a new service, generator, or utility for adherence to project patterns
  • Evaluating MCP gateway handler implementations

Project Standards

TypeScript Configuration

  • Target: ES2020, Module: CommonJS
  • Strict mode enabled ("strict": true)
  • Declarations and source maps generated
  • Path alias: @generators/agents/* maps to src/generators/agents/*

Code Organization Patterns

Service Layer (22 services in src/services/):

  • Each service lives in its own directory under src/services/
  • Exports through index.ts barrel files
  • Constructor takes an options object or required config
  • Methods are async where I/O is involved
  • Example: FillService, WorkflowService, AIContextMCPServer

Generators (src/generators/):

  • Separate generators for docs, agents, plans, skills
  • Accept options objects, return typed result objects (e.g., SkillGeneratorResult)
  • Use frontmatter serialization from src/types/scaffoldFrontmatter.ts

Utilities (src/utils/):

  • Pure functions or thin wrappers: frontMatter.ts, contentSanitizer.ts, gitService.ts
  • CLI UI abstraction: cliUI.ts with CLIInterface type
  • i18n: i18n.ts with TranslateFn type and en/pt-BR locale support

MCP Gateway Handlers (src/services/mcp/gateway/):

  • One file per gateway: explore.ts, context.ts, sync.ts, etc.
  • Exports: handler function, params type, options type, action type
  • Uses createJsonResponse/createErrorResponse/createTextResponse from response.ts
  • Barrel re-export through index.ts and gatewayTools.ts

Review Checklist

Architecture
  • New code follows the service/generator/util separation
  • No direct file I/O in generators -- delegate to services or fs-extra
  • MCP handlers do not use console.log (use process.stderr.write for debug output)
  • repoPath is never hardcoded; always resolved through options or getRepoPath()

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.

Code Review is a skill published in the GitHub repository vinilana/dotcontext (561 stars, last pushed 1mo ago), licensed MIT. It adds 12 tokens to every session and 1,427 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
