Optimize Index Retrieval

Optimize Index Retrieval

Goal

Implement a strict, reusable optimization standard for complex index retrieval flows. Keep retrieval and decision semantics unchanged; optimize only response shaping, context budget control, and retry guidance.

Non-Goals

• Change scoring logic, thresholds, or label mapping.
• Redesign business workflow beyond retrieval context control.
• Replace domain datasets, schema, or storage models.

Workflow

1. Freeze semantics first.

• Keep labels, thresholds, scoring weights, and ranking logic unchanged.
• Limit changes to response contract, payload control, and observability.

2. Add context-control inputs.

• Add response profile with exactly two values: compact|full.
• Default compact for heavy decision/intake commands.
• Default full for diagnostic and low-volume commands.
• Add payload budget in KB, default 20 (20*1024 UTF-8 bytes).
• Clamp retrieval limit to 1..20; report both requested and effective values.

3. Add oversize observability.

• Never silently truncate full output.
• Always compute payload bytes with UTF-8 serialized output.
• After profile + field mask are applied, run oversize check.
• If oversized, keep output visible and append:
  • meta.contextControl.oversize=true
  • meta.contextControl.thresholdBytes
  • meta.contextControl.payloadBytes
  • meta.contextControl.oversizeStage
  • meta.contextControl.stageBreakdown
  • meta.contextControl.optimizationHints
  • meta.contextControl.limitAdjusted.requested/effective when limit applies.

4. Provide explicit next-call hints.

• Generate at least 2 directly executable hint commands.
• Hints must prioritize:
  • switch to compact profile,
  • reduce limit (for example 20 -> 10 -> 5),
  • narrow fields,
  • split one heavy call into staged calls.
• For text mode, print an OVERSIZE_HINT block with copyable commands.

5. Validate with contract + child-runner + perf benchmark.

• Add contract tests for profile defaults, limit clamp, payload budget, oversize metadata completeness.
• Add output tests for json/text/ndjson consistency.
• Add child-runner simulation: first call oversized, second call follows hint and payload decreases while key decision fields remain available.
• Run scripts/benchmark_context_control.py to compare profiles and report payload/latency deltas.

Required Contract

Load and apply references/context-control-standard.md as the authoritative output contract.

Performance Benchmark Capability

Use bundled script: ./scripts/benchmark_context_control.py

Example:

python ./scripts/benchmark_context_control.py `
  --command-template "python skills/p1max-qa-playbook-workflow/workflow.py triage.decide --source internal --params @tmp/triage_input.json --payload-budget-kb 20 --response-profile {profile} --output json" `
  --stdout-format auto `
  --rounds 10 `
  --profile-a full `
  --profile-b compact `
  --min-payload-drop-pct 50

Expected use:

• Confirm payload reduction is substantial.
• Confirm latency regression is controlled.
• Produce JSON summary for release notes or review comments.
• Set --stdout-format ndjson when the target command emits NDJSON.

Delivery Checklist

• Contract fields exist and are populated when oversized.
• fields keeps highest priority and still triggers oversize evaluation.
• No scoring/decision semantic change is introduced.
• Tests include child-runner guided retry.
• Benchmark script output is attached in review.
