Effective optimization increases useful capacity without requiring larger models or longer windows — but only when applied with measurement discipline. The techniques below are ordered by impact and risk.\n\n## When to Activate\n\nActivate this skill when:\n- Context budgets or token costs constrain task complexity\n- Observation masking can replace verbose tool outputs with retrievable references\n- Prefix or KV-cache hit rate needs improvement\n- Retrieval scoping can reduce irrelevant loaded context\n- Context partitioning can extend effective capacity across agents\n- Budget triggers are needed for masking, compaction, or partitioning\n\nDo not activate this skill for adjacent work owned by other skills:\n- Explaining why attention or context windows behave this way: `context-fundamentals`.\n- Diagnosing active lost-in-middle, poisoning, distraction, confusion, or clash: `context-degradation`.\n- Designing a structured handoff summary for a long conversation: `context-compression`.\n- Storing large outputs, plans, or logs as files: `filesystem-context`.\n\n## Core Concepts\n\nApply four primary strategies in this priority order:\n\n1. **KV-cache optimization** — Reorder and stabilize prompt structure so the inference engine reuses cached Key/Value tensors. This is the cheapest optimization when the runtime supports prefix caching: low quality risk, immediate cost and latency savings. Apply it first when stable prefixes exist.\n\n2. **Observation masking** — Replace verbose tool outputs with compact references once their purpose has been served. Tool outputs can dominate agent trajectories (claim-context-optimization-tool-output-dominance), so masking often yields the largest capacity gains. The original content remains retrievable if needed downstream.\n\n3. **Compaction** — Summarize accumulated context when utilization exceeds 70%, then reinitialize with the summary. This distills the window's contents while preserving task-critical state. Compaction is lossy — apply it after masking has already removed the low-value bulk.\n\n4. **Context partitioning** — Split work across sub-agents with isolated contexts when a single window cannot hold the full problem. Each sub-agent operates in a clean context focused on its subtask. Reserve this for tasks where estimated context exceeds 60% of the window limit, because coordination overhead is real.\n\nThe governing principle: context quality matters more than quantity. Every optimization preserves signal while reducing noise. Measure before optimizing, then measure the optimization's effect.\n\n## Detailed Topics\n\n### Compaction Strategies\n\nTrigger compaction when context utilization exceeds 70%: summarize the current context, then reinitialize with the summary. This distills the window's contents in a high-fidelity manner, enabling continuation with minimal performance degradation. Prioritize compressing tool outputs first (they consume 80%+ of tokens), then old conversation turns, then retrieved documents. Never compress the system prompt — it anchors model behavior and its removal causes unpredictable degradation.\n\nPreserve different elements by message type:\n\n- **Tool outputs**: Extract key findings, metrics, error codes, and conclusions. Strip verbose raw output, stack traces (unless debugging is ongoing), and boilerplate headers.\n- **Conversational turns**: Retain decisions, commitments, user preferences, and context shifts. Remove filler, pleasantries, and exploratory back-and-forth that led to a conclusion already captured.\n- **Retrieved documents**: Keep claims, facts, and data points relevant to the active task. Remove supporting evidence and elaboration that served a one-time reasoning purpose.\n\nTarget 50-70% token reduction with less than 5% quality degradation. If compaction exceeds 70% reduction, audit the summary for critical information loss — over-aggressive compaction is the most common failure mode.\n\n### Observation Masking\n\nMask observations selectively based on recency and ongoing relevance — not uniformly. Apply these rules:\n\n- **Never mask**: Observations critical to the current task, observations from the most recent turn, observations used in active reasoning chains, and error outputs when debugging is in progress.\n- **Mask after 3+ turns**: Verbose outputs whose key points have already been extracted into the conversation flow. Replace with a compact reference: `[Obs:{ref_id} elided. Key: {summary}. Full content retrievable.]`\n- **Always mask immediately**: Repeated/duplicate outputs, boilerplate headers and footers, outputs already summarized earlier in the conversation.\n\nMasking should achieve 60-80% reduction in masked observations with less than 2% quality impact. The key is maintaining retrievability — store the full content externally and keep the reference ID in context so the agent can request the original if needed.\n\n### KV-Cache Optimization\n\nMaximize prefix cache hits by structuring prompts so that stable content occupies the prefix and dynamic content appears at the end. KV-cache stores Key and Value tensors computed during inference; when consecutive requests share an identical prefix, the cached tensors are reused, saving both cost and latency.\n\nApply this ordering in every prompt:\n1. System prompt (most stable — never changes within a session)\n2. Tool definitions (stable across requests)\n3. Frequently reused templates and few-shot examples\n4. Conversation history (grows but shares prefix with prior turns)\n5. Current query and dynamic content (least stable — always last)\n\nDesign prompts for cache stability: remove timestamps, session counters, and request IDs from the system prompt. Move dynamic metadata into a separate user message or tool result where it does not break the prefix. Even a single whitespace change in the prefix invalidates the entire cached block downstream of that change.\n\nTarget 70%+ cache hit rate for stable workloads. At scale, this translates to 50%+ cost reduction and 40%+ latency reduction on cached tokens.\n\n### Context Partitioning\n\nPartition work across sub-agents when a single context cannot hold the full problem without triggering aggressive compaction. Each sub-agent operates in a clean, focused context for its subtask, then returns a structured result to a coordinator agent.\n\nPlan partitioning when estimated task context exceeds 60% of the window limit. Decompose the task into independent subtasks, assign each to a sub-agent, and aggregate results. Validate that all partitions completed before merging, merge compatible results, and apply summarization if the aggregated output still exceeds budget.\n\nThis approach achieves separation of concerns — detailed search context stays isolated within sub-agents while the coordinator focuses on synthesis. However, coordination has real token cost: the coordinator prompt, result aggregation, and error handling all consume tokens. Only partition when the savings exceed this overhead.\n\n### Budget Management\n\nAllocate explicit token budgets across context categories before the session begins: system prompt, tool definitions, retrieved documents, message history, tool outputs, and a reserved buffer (5-10% of total). Monitor usage against budget continuously and trigger optimization when any category exceeds its allocation or total utilization crosses 70%.\n\nUse trigger-based optimization rather than periodic optimization. Monitor these signals:\n- Token utilization above 80% — trigger compaction\n- Attention degradation indicators (repetition, missed instructions) — trigger masking + compaction\n- Quality score drops below baseline — audit context composition before optimizing\n\n## Practical Guidance\n\n### Optimization Decision Framework\n\nSelect the optimization technique based on what dominates the context:\n\n| Context Composition | First Action | Second Action |\n|---|---|---|\n| Tool outputs dominate (>50%) | Observation masking | Compaction of remaining turns |\n| Retrieved documents dominate | Summarization | Partitioning if docs are independent |\n| Message history dominates | Compaction with selective preservation | Partitioning for new subtasks |\n| Multiple components contribute | KV-cache optimization first, then layer masking + compaction |\n| Near-limit with active debugging | Mask resolved tool outputs only — preserve error details |\n\n### Performance Targets\n\nTrack these metrics to validate optimization effectiveness:\n\n- **Compaction**: 50-70% token reduction, <5% quality degradation, <10% latency overhead from the compaction step itself\n- **Masking**: 60-80% reduction in masked observations, <2% quality impact, near-zero latency overhead\n- **Cache optimization**: 70%+ hit rate for stable workloads, 50%+ cost reduction, 40%+ latency reduction\n- **Partitioning**: Net token savings after accounting for coordinator overhead; break-even typically requires 3+ subtasks\n\nIterate on strategies based on measured results. If an optimization technique does not measurably improve the target metric, remove it — optimization machinery itself consumes tokens and adds latency.\n\n## Examples\n\n**Example 1: Compaction Trigger**\n```python\nif context_tokens / context_limit > 0.8:\n    context = compact_context(context)\n```\n\n**Example 2: Observation Masking**\n```python\nif len(observation) > max_length:\n    ref_id = store_observation(observation)\n    return f\"[Obs:{ref_id} elided. Key: {extract_key(observation)}]\"\n```\n\n**Example 3: Cache-Friendly Ordering**\n```python\n# Stable content first\ncontext = [system_prompt, tool_definitions]  # Cacheable\ncontext += [reused_templates]  # Reusable\ncontext += [unique_content]  # Unique\n```\n\n**Example 4: Budget-triggered optimization policy**\n```yaml\nbudgets:\n  tool_outputs: 35%\n  message_history: 30%\n  retrieved_documents: 20%\n  reserved_buffer: 15%\ntriggers:\n  tool_outputs_over_budget: mask resolved observations\n  total_context_over_70_percent: compact message history\n  repeated_irrelevant_retrievals: tighten retrieval scope\n```\n\n## Guidelines\n\n1. Measure before optimizing—know your current state\n2. Apply masking before compaction — remove low-value bulk first, then summarize what remains\n3. Design for cache stability with consistent prompts\n4. Partition before context becomes problematic\n5. Monitor optimization effectiveness over time\n6. Balance token savings against quality preservation\n7. Test optimization at production scale\n8. Implement graceful degradation for edge cases\n\n## Gotchas\n\n1. **Whitespace breaks KV-cache**: Even a single whitespace or newline change in the prompt prefix invalidates the entire KV-cache block downstream of that point. Pin system prompts as immutable strings — do not interpolate timestamps, version numbers, or session IDs into them. Diff prompt templates byte-for-byte between deployments.\n\n2. **Timestamps in system prompts destroy cache hit rates**: Including `Current date: {today}` or similar dynamic content in the system prompt forces a full cache miss on every new day (or every request, if using time-of-day). Move dynamic metadata into a user message or a separate tool result appended after the stable prefix.\n\n3. **Compaction under pressure loses critical state**: When the model performing compaction is itself under context pressure (>85% utilization), its summarization quality degrades — it omits task goals, drops user constraints, and flattens nuanced state. Trigger compaction at 70-80%, not 90%+. If compaction must happen late, use a separate model call with a clean context containing only the material to summarize.\n\n4.
