## Summary
- require the main agent to read selected `SKILL.md` files completely,
continuing truncated or paginated reads through EOF
- require the main agent to personally read task-required instruction
references instead of delegating their interpretation
- clarify that progressive disclosure selects relevant files without
permitting partial reads
- preserve subagent use for task work when the selected skill allows it
- cover both absolute-path and aliased-root prompt variants
## Why
Partial reads can skip routing and verification requirements later in
skill instructions. Delegated summaries can also omit constraints the
main agent needs to follow. The existing "Read only enough" wording made
both behaviors appear acceptable.
## Impact
Agents should follow complete selected skill instructions while
continuing to avoid unrelated references, scripts, and assets. Subagents
remain available for task execution where permitted.
## Test plan
- `just test -p codex-core-skills` (101 passed)
- `just fmt`
- `git diff --check`
