Quotes worth keeping#

On why firstmate exists#

it was to create an experience. a feeling. a sense of peacefulness that was taken away by the noisy agents... it's the experience of being a good captain that sails with a well-managed crew, with the help of a firstmate that carries out the captain's direction. — 2026-08-10

firstmate is THE chief of staff - it's probably the project that pushed the furthest on this pattern. the most common feedback from people who have adopted firstmate is 'there's no way to go back.' — 2026-09-07

chat, as a sequential stream of messages, has a fundamental flaw that it's chronologically structured and assumes a turn by turn interaction... the most important thing that needs my attention is often not the latest thing at the bottom of the chat. — 2026-08-19

That is why /bearings and /ahoy exist.

On design#

the agent's context window is like our computer's 'memory'... anything that needs to serve as a durable record should not be trusted to stay only in the context window. they must be pushed and persisted onto the disk, and made discoverable by the agent. — 2026-08-31

this setup allows the agent to be completely self-aware and self-evolvable. it can answer any question about its own behavior, and it can change every bit of itself according to your needs (now the unintended side effect is that i have 500+ PRs coming from everyone using their firstmate to self evolve). — 2026-08-10

firstmate runs in the orchestrator pattern by default. it plans and delegates work to crewmates. and when a crewmate runs into problems, they escalate back to firstmate for guidance. — 2026-07-08

one fresh example of the advantage of being vendor-agnostic - i could ship a jev integration in firstmate the same day jev was released. anthropic can't. — 2026-09-17

On agents and code#

i'm slowly realizing that the code i'm writing is no longer code... it's intent. it's 'here's what i want.' intent doesn't crash and can't be broken. — 2026-07-17

What happened when a firstmate script broke: "it ran the script, saw it fail, created a workaround, and recorded a memory to use the workaround ever since."

use a proper validation pipeline like /no-mistakes — the impact is equal to introducing peer review and CI to a team where everyone always push directly to main. — 2026-07-03

sol will remodel my kitchen before making me breakfast. opus 5 will go down rabbit holes and come back with an essay but no rabbit. — 2026-08-13

one thing the recent model releases have consistently told us is that public benchmarks are completely useless now — 2026-09-04
