# ADR-0006: Full-document rule delivery, no dynamic subsetting

**Status:** Accepted (2026-08-08) — carried forward from the original design doc

## Context

An obvious token-saving optimization is to send an agent only the slice of the ruleset relevant to
its current task or file path. This was considered and rejected during design.

## Decision

The rendered rules document is **always sent in full**. No path-based or task-based filtering of
what an agent receives.

How much leash a given model needs to reliably stay on task is a **per-model concern handled by the
renderer** (ADR-0012), not a universal token-saving optimization applied to everyone. Some
models need a fuller, more complete document than others.

## Consequences

- Predictable behavior: an agent's context either contains the whole policy or the session is
  gated (ADR-0005).
- Higher token cost per session, accepted deliberately.
- Renderer verbosity becomes the tuning knob for per-model needs.
- Note that this reasoning applies to **rules**, not to **tools**. Tool schemas are a separate
  context budget and *are* filtered per agent, driven by the permissions table (see phase 3).
