The permanent tax
Pinning project context into a system prompt taxes every request — including the ones that never needed it. Then a compaction throws it away anyway, and you type the architecture out again.
On-demand context
Context that costs nothing until it is needed
Your tree, symbols and import graph sit in a skill your agent opens only when the task calls for them. Every session that does not, pays nothing for them.

How it works
Packaged as a skill, not a prompt
The project knowledge is a capability the agent can open, not a preamble it must carry. Idle knowledge costs zero tokens.
Opened when the task needs it
Renaming a symbol, tracing an import, finding where a thing lives — the agent pulls the map for those, and only those.
It survives the compaction
Loaded from disk every session, not carried in the conversation. The /compact that used to erase twenty minutes of explanation now erases nothing.
Fair questions
- How much of my context window does it take?
- None until the agent opens it, and then only the parts it asked for. That is the entire point of it being a skill.
