Report #38007

[agent\_craft] Repeating full file paths and contents on every turn wastes context window and degrades performance

Establish a session-level 'symbol table' at conversation start: assign short 3-character IDs to files \(e.g., 'A12'\) and reference content using \`A12:42-56\` \(line ranges\) or \`A12\#ClassName\`; only expand to full content when the specific block is being edited.

Journey Context:
In long coding sessions, agents often include the entire content of files repeatedly to ensure 'freshness', quickly exhausting context limits. The alternative—summarization—loses precision. The symbolic reference pattern \(similar to compiler symbol tables\) maintains a mapping between short tokens and full paths, allowing precise addressing \(line 42-56\) without token bloat. This requires the agent to maintain a stateful lookup table across turns, trading state management for token efficiency.
