Aetox Orient

A project is read from the cheapest layer outward, and each layer says which part of the next one to open. Reading a whole file to find out what it is, is the failure this discipline exists to stop: the week this app's map was built against counted eighteen whole reads of 50 KB or more, and the two largest were architecture documents read end to end for one section.

Layer 0: what the conversation already holds

Before any tool: the project's own file (AETOX.md, AGENTS.md or CLAUDE.md, already in your context when it exists) and the project memory lines that earlier sessions wrote. They are what this project settled — the command that proves a change, the folder that is generated, the convention nobody wrote down elsewhere. An instruction there outranks a guess from the tree.

Layer 1: the shape, once

codebase with action: map, the whole project, one call per conversation. It costs about a thousand tokens and returns files ranked by how many other files use them, with their symbols and line numbers:

• The first files are the ones the project leans on: its types, its

config, its registry. A change that touches one of them reaches everywhere; a change that touches none is local.

• Markdown files appear as heading outlines, so an architecture document is

opened at the section, never end to end.

• "N more files under the budget line" means the map was cut to fit. Map

the folder the task lives in (path) to see that folder deeper; do not map the whole project again.

• The map refuses when no project is focused; that is the answer, not an

error to route around.

Layer 2: the name, exactly

Before changing an identifier, codebase with action: symbol: the declaration, its signature and every reference. That list is the blast radius of the change, and it is exact where a search guesses. Use search for text — a string in a message, a word in a comment — and symbol for names.

Layer 3: the lines, not the file

read with offset and limit at the line the map or the symbol named, and enough around it to see the function whole. A whole file is read when its size is known to be small or when the task is the file itself; a whole read of something large is said out loud, with the reason.

Layer 4: the code's own verdict

After editing, codebase with action: errors on the files touched — the language server's compile and type errors, which a test run reports later and less precisely. Then the proof aetox-verify asks for.

Closing: one line for the next session

What this work taught that the code does not say — a trap, a convention, the command that proves this project — goes to memory as one line. It is what Layer 0 will hold next time. Narrating what was read is not that; the map and the files are there to be read again.

Not this

• Mapping, then reading the top file whole anyway.
• Announcing the layers. Orientation is part of the work, not a report on

it; the user asked for the change.

• Skipping to search because it is familiar. A search finds where a word

appears; the map says what the project is made of, and the symbol says what a name is. Three questions, three tools.
