How we build: Tailor.ia Lean
At Tailor.ia we code with Claude Code every day. Tailor.ia Lean is the plugin we distilled from that practice: it makes the AI spend fewer tokens and make fewer mistakes. It is free, open source, serverless and telemetry-free.
Install on Claude Code
/plugin marketplace add ffid-br/tailor-ia-lean
/plugin install tailor-ia-leanOpen a new session. The rules load on their own at the start of each session, in about 350 tokens. It also works on Codex.
The routine with it
- /lean
- The why behind each rule, with before and after examples. Start here.
- /orquestrar
- The expensive model thinks and the cheap one executes. For tasks that touch three or more files.
- /fluxo-dev
- From ticket to merge: branch, tests, PR and memory, no ceremony.
- /fechar
- At the end of the session, saves to docs/memoria what isn't in the code and says whether it's time for /compact or /clear.
The three agents it brings
batedorHaiku
Locates: file and line, who calls what, folder map. Proposes no fix.
operarioSonnet
Implements an already specified step, in up to three files, and runs the tests.
revisorSonnet
Lists the diff's defects, one line each. No praise.
What it changed in the benchmark
- 14%
- cheaper
- ½
- of Opus's turns
- 56%
- less context re-read
- 28%
- fewer output tokens
Opus 5.5 in command, three real tasks on a frontend of about a thousand files, five repetitions. The first round, with Sonnet, went against the plugin and is also published.
Even better together with caveman, which compresses the prose of the reply, and ponytail, which forces the simplest solution that works.
