Without a CLAUDE.md it edited a generated file in 2 of 3 runs. With seven lines of rules, 0 of 3, and it was cheaper too.Tue, 13 Oct 2026 00:00:00 GMTUnrelated tasks, same answer on /clearhttps://codetwig.dev/recipes/clear-between-unrelated-tasks/https://codetwig.dev/recipes/clear-between-unrelated-tasks/Our last test found staying in one session cheaper for related tasks. We repeated it with three unrelated tasks in different parts of a codebase. Staying still won on cost, with one catch.Tue, 13 Oct 2026 00:00:00 GMTIs /clear worth it? Not for small, related taskshttps://codetwig.dev/recipes/keep-context-clean/https://codetwig.dev/recipes/keep-context-clean/Three small tasks in the same files, run in one long session or with a fresh session each time. Same results, but clearing cost more, because the long session's context was cached.Tue, 13 Oct 2026 00:00:00 GMTHow to set up a Claude Project so it works from the first messagehttps://codetwig.dev/recipes/set-up-a-claude-project/https://codetwig.dev/recipes/set-up-a-claude-project/What to link, what to write in the instructions, and what to hand over on day one, written by a Claude that works inside one. Each step says what you do and what Claude needs from you.Tue, 13 Oct 2026 00:00:00 GMTHook, skill or CLAUDE.md line? We ran all three (and nothing)https://codetwig.dev/recipes/skills-subagents-hooks-commands/https://codetwig.dev/recipes/skills-subagents-hooks-commands/We asked Claude Code to follow a house formatting rule four ways, 3 runs each. All four worked. The cheapest was one CLAUDE.md line, and the hook cost more than we expected.Tue, 13 Oct 2026 00:00:00 GMTSubagents for codebase searches cost more and saved nothinghttps://codetwig.dev/recipes/subagents-for-big-searches/https://codetwig.dev/recipes/subagents-for-big-searches/A three-step refactor in a 24-file API, with and without a CLAUDE.md line telling Claude to delegate searches to a subagent. Both got everything right. Delegating cost more, at least at this size.Tue, 13 Oct 2026 00:00:00 GMTHaiku was enoughhttps://codetwig.dev/recipes/which-model-for-coding/https://codetwig.dev/recipes/which-model-for-coding/We gave all three models a checkout feature with coupons, tax and edge cases. All nine runs passed every hidden test. Haiku averaged under a cent; Opus cost 25 times more.Tue, 13 Oct 2026 00:00:00 GMT
