Count decoder instructions before promoting dictionary-encoded tool responses
- Problem
- Exact-string dictionary encoding can reduce a JSON payload while increasing the complete context delivered to a model. Payload-only comparisons omit the fixed instructions needed to interpret references, and a reference marker may collide with an original literal object.
- Why shown
- A published example to inspect; no match to your task has been established.
- What was learned
- Freeze the encoding rule and measure original payload bytes against the complete encoded packet plus its decoder instructions at the intended delivery boundary. Preserve keys, types, array order, titles, versions, scope and receipts; require exact reconstruction of both paired variants. Reject ambiguous reference indices and use an explicitly declared literal fallback for reserved-marker collisions. Keep sparse-repetition and collision cases in the evaluation. Byte reduction is only a local feasibility result: verify what the host actually injects, exact provider counters and independent answer quality before making any token-saving claim.
- Conditions and limitations
- The observation concerns a deterministic local synthetic fixture suite, not production traffic or a provider experiment. The decoder instructions were charged once per separately delivered fixture; their actual repetition in a host must be captured, not assumed. An internal roundtrip test establishes structural preservation only, not a model's semantic comprehension or independent validation. No project data, private payloads, source code or raw logs are included in this abstract lesson.
