CodeBurn Development Rules

Verification

• NEVER commit without running locally first and confirming it works
• Run npx tsx src/cli.ts report and npx tsx src/cli.ts today to verify changes before any commit
• For dashboard changes: run the interactive TUI and visually confirm rendering
• For new features: test the happy path AND edge cases (empty data, missing config, pipe mode)

Code Quality

• Clean, minimal code. No dead code, no commented-out blocks, no TODO placeholders
• No emoji anywhere in the codebase
• No em dashes. Use hyphens or rewrite the sentence
• No AI slop: no "streamline", "leverage", "robust", "seamless" in user-facing text
• No unnecessary abstractions. Three similar lines > premature helper function
• No magic numbers. Extract layout offsets, column widths, thresholds, timeouts, and any value used in a calculation into a named const at module scope. Inline literals are only OK for universally understood constants (0, 1, 100 for percent). If a number appears in a formula like pw - bw - 31, the 31 must be a named constant.

Accuracy

• Every user-facing number (cost, tokens, calls) must be verified against real data
• LiteLLM pricing model names must match exactly. No guessing model IDs
• Date range calculations must be tested with edge cases (month boundaries, billing day > days in month)

Style

• TypeScript strict mode. No any types
• No comments unless the WHY is non-obvious
• Imports: node builtins first, then deps, then local (separated by blank line)
• Single quotes, no semicolons inconsistency (follow existing: no trailing semicolons in most files)

Git

Branching (strict)

• NEVER commit directly to main. All work happens on branches
• Branch naming: feat/<name>, fix/<name>, chore/<name>, docs/<name>
• Merge to main ONLY after: tests pass, CLI verified, manual testing done
• npm publish ONLY from main after merge
• Tag releases: git tag v0.X.0 after publish

Creating a branch

git checkout main && git pull origin main
git checkout -b feat/my-feature
# work, test, iterate
npx vitest run
npx tsx src/cli.ts report
# when ready:
git checkout main && git merge feat/my-feature
git push origin main

Handling external PRs

• NEVER rewrite a contributor's changes on your own branch. Always merge THEIR branch
• Add your improvements as separate commits on top of their branch, not as replacements
• This preserves their authorship in git history so GitHub shows them as a contributor

gh pr checkout <number>           # checkout PR locally
npx vitest run                    # test their code
npx tsx src/cli.ts report         # manual verification
# apply patches if needed, commit on their branch
git checkout main
git merge <branch>                # preserves their authorship
git push origin main
gh pr comment <number> --body "Merged, thanks!"

What gets committed

• Source code: src/, tests/
• Config: package.json, tsconfig.json, tsup.config.ts, .gitignore
• Docs: README.md, CHANGELOG.md, LICENSE, CLAUDE.md
• Assets: assets/
• NEVER commit: .env, secrets, keys, planning docs (docs/superpowers/), IDE config, logs, .DS_Store
• Check git status before every commit. Stage specific files, never git add -A or git add .

Commit rules

• Commits from: AgentSeal hello@agentseal.org
• NEVER add Co-Authored-By lines
• NEVER include personal names or usernames in commits
• Small, focused commits. One feature per commit
• Test locally before every commit
