Claude Code
Strong for interactive coding loops, plans, and repo-aware agent sessions.
Stack
Three primary tools. No Cursor homepage card for now. Availability is separate from article status.
| Tool | Best stage | Best for | Poor fit | Caveats | Availability |
|---|---|---|---|---|---|
| Claude Code | build | Repo-local agent loops, plan-then-implement sessions, and rules/hooks enforcement. | Blind one-shot generation without a verification command; treating chat memory as policy. | Keep secrets out of prompts; encode hard no-gos in rules files and hooks, not hopes. | active |
| Codex | build | Spec-driven coding tasks, batchable edits, and CLI-centered workflows. | Vague product ideas with no acceptance tests; skipping human review on security-sensitive diffs. | Product surfaces evolve; pin docs links and re-check commands after upgrades. | active |
| Grok Build | sell | Fast shipping and demo-oriented build loops once the spec is clear. | Deep proprietary enterprise workflows that require vendor-specific compliance tooling only available elsewhere. | Treat Grok Build as one node in the OPC stack; keep Claude Code/Codex for heavy repo policy when needed. Re-verify commands against live docs. | active |
