1# ECC for Gemini CLI
2 
3This file provides Gemini CLI with the baseline ECC workflow, review standards, and security checks for repositories that install the Gemini target.
4 
5## Overview
6 
7Everything Claude Code (ECC) is a cross-harness coding system with 36 specialized agents, 142 skills, and 68 commands.
8 
9Gemini support is currently focused on a strong project-local instruction layer via `.gemini/GEMINI.md`, plus the shared MCP catalog and package-manager setup assets shipped by the installer.

11## Core Workflow
12 
131. Plan before editing large features.
142. Prefer test-first changes for bug fixes and new functionality.
153. Review for security before shipping.
164. Keep changes self-contained, readable, and easy to revert.

18## Coding Standards
19 
20- Prefer immutable updates over in-place mutation.
21- Keep functions small and files focused.
22- Validate user input at boundaries.
23- Never hardcode secrets.
24- Fail loudly with clear error messages instead of silently swallowing problems.

26## Security Checklist
27 
28Before any commit:
29 
30- No hardcoded API keys, passwords, or tokens
31- All external input validated
32- Parameterized queries for database writes
33- Sanitized HTML output where applicable
34- Authz/authn checked for sensitive paths
35- Error messages scrubbed of sensitive internals
36 
37## Delivery Standards
38 
39- Use conventional commits: `feat`, `fix`, `refactor`, `docs`, `test`, `chore`, `perf`, `ci`
40- Run targeted verification for touched areas before shipping
41- Prefer contained local implementations over adding new third-party runtime dependencies
42 
43## ECC Areas To Reuse
44 
45- `AGENTS.md` for repo-wide operating rules
46- `skills/` for deep workflow guidance
47- `commands/` for slash-command patterns worth adapting into prompts/macros
48- `mcp-configs/` for shared connector baselines
