# Sync Everything Claude Code (ECC) assets into a local Codex CLI setup.
# - Backs up ~/.codex config and AGENTS.md
# - Merges ECC AGENTS.md into existing AGENTS.md (marker-based, preserves user content)
# - Generates prompt files from commands/*.md
# - Generates Codex QA wrappers and optional language rule-pack prompts
# - Installs global git safety hooks (pre-commit and pre-push)
# - Runs a post-sync global regression sanity check
# - Merges ECC MCP servers into config.toml (add-only via Node TOML parser)

# ECC Tool Prompt: run-tests

Run the repository test suite with package-manager autodetection and concise reporting.

## Instructions
1. Detect package manager from lock files in this order: \`pnpm-lock.yaml\`, \`bun.lockb\`, \`yarn.lock\`, \`package-lock.json\`.
2. Detect available scripts or test commands for this repo.
3. Execute tests with the best project-native command.
4. If tests fail, report failing files/tests first, then the smallest likely fix list.
5. Do not change code unless explicitly asked.

## Output Format
\`\`\`
RUN TESTS: [PASS/FAIL]
Command used: <command>
Summary: <x passed / y failed>
Top failures:
- ...
Suggested next step:

write_extension_prompt "ecc-tool-check-coverage.md" <<EOF
# ECC Tool Prompt: check-coverage

Analyze coverage and compare it to an 80% threshold (or a threshold I specify).

## Instructions
1. Find existing coverage artifacts first (\`coverage/coverage-summary.json\`, \`coverage/coverage-final.json\`, \`.nyc_output/coverage.json\`).
2. If missing, run the project's coverage command using the detected package manager.
3. Report total coverage and top under-covered files.
4. Fail the report if coverage is below threshold.

## Output Format
\`\`\`
COVERAGE: [PASS/FAIL]
Threshold: <n>%
Total lines: <n>%
Total branches: <n>% (if available)
Worst files:
- path: xx%
Recommended focus:

EOF

write_extension_prompt "ecc-tool-security-audit.md" <<EOF
# ECC Tool Prompt: security-audit

Run a practical security audit: dependency vulnerabilities + secret scan + high-risk code patterns.

## Instructions
1. Run dependency audit command for this repo/package manager.
2. Scan source and staged changes for high-signal secrets (OpenAI keys, GitHub tokens, AWS keys, private keys).
3. Scan for risky patterns (\`eval(\`, \`dangerouslySetInnerHTML\`, unsanitized \`innerHTML\`, obvious SQL string interpolation).
4. Prioritize findings by severity: CRITICAL, HIGH, MEDIUM, LOW.
5. Do not auto-fix unless I explicitly ask.
