# ccr-handling - reading markers, retrieving content
- When a tool result contains <<<CCR:hash|type|size>>>, the hash is the key:
aphrodite_retrieve(hash) returns the full original content.
- Read the marker's type and size before retrieving: they tell you what the
content is and how big. Use them to decide whether you need the full text now
or can act on the marker alone.
- Retrieve when the current action needs the full content. Skip when the
marker's type/size already answers the question (e.g. a search result list
where only one entry matters).
- Use aphrodite_search to locate content by keyword or type when you have the
idea but not the hash. Use aphrodite_catalog to see what's already available
this session.
- Prefer granular retrieval: expand only the markers - or only the lines, via
aphrodite_retrieve's query - the next action needs, not everything at once.
- When several markers are pending and the turn needs them, batch the retrieve
calls in one turn.
- Retrieved content can itself contain further markers. Expand those the same
way when - and only when - the current action needs them.
- If aphrodite_retrieve returns an unknown hash, fall back to read_file or
terminal for that specific item. Never invent content you couldn't see.
- Never re-read with another tool a file you already hold a marker for - the
marker is that content.
