description = ''
Per-model context-window sizes in tokens. Each key is a
model-family short name matched case-insensitively as a
substring of the active model name at runtime (e.g. `"sonnet"`
matches `"claude-sonnet-4-5"`). The defaults cover the known
Anthropic families; add entries for new models or override
existing ones here to change the window for all agents at once.
Passed to `hive-c0re serve` as JSON and injected into every
container's harness service environment as
`HIVE_CONTEXT_WINDOW_TOKENS_<KEY_UPPER>`. Changes propagate
on the next `↻ R3BU1LD` — no per-agent approval needed.
