Tier 1 always overrides Tier 2/3 - research patterns + token efficiency are non-negotiable
Deep analysis against research patterns + token metrics
1. Read target prompt from $ARGUMENTS
2. Assess type (command, agent, subagent, workflow)
3. **CRITICAL ANALYSIS**:
- Critical rules position? (should be <15%)
- Max nesting depth? (should be ≤4)
- Instruction ratio? (should be 40-50%)
- Rule repetitions? (should be 1x + refs)
- Explicit prioritization? (should exist)
- Token count baseline? (measure for reduction)
4. Calculate component ratios
5. Identify anti-patterns & violations
6. Determine complexity level
Find first critical instruction→Calculate position %→Flag if >15%
Count max XML depth→Flag if >4 levels
Calculate instruction %→Flag if >60% or <40%
Find repeated rules→Flag if same rule 3+ times
Count tokens/words/lines→Establish baseline for reduction target
Critical rules <15%? (3 pts - HIGHEST)
Max depth ≤4? (2 pts)
Instructions 40-50%? (2 pts)
Rules defined once? (1 pt)
Priority system exists? (1 pt)
External refs used? (1 pt)
Potential for 30-50% reduction? (3 pts - NEW)
100% meaning preservable? (2 pts - NEW)
X/15 with violations flagged
Lines, words, estimated tokens
CRITICAL, MAJOR, MINOR
simple | moderate | complex
Prioritized by impact (Tier 1 first)
Move critical rules to first 15%
Analysis complete, rules identified
Position sensitivity: early placement improves adherence
1. Extract all critical/safety rules
2. Create block
3. Position immediately after (within 15%)
4. Assign unique IDs

6. Verify position <15%
Clear, concise statement
Rules at <15%, unique IDs, refs work
Reduce nesting from 6-7 to 3-4 levels
Critical rules elevated
Excessive nesting reduces clarity
1. Identify deeply nested sections (>4 levels)
2. Convert nested elements→attributes where possible
3. Extract verbose sections→external refs
4. Flatten decision trees using attributes
5. Verify max depth ≤4
Condition
Max nesting ≤4, attributes for metadata, structure clear
Reduce tokens 30-50% while preserving 100% semantic meaning
Nesting flattened
Real-world optimization learnings: visual operators + abbreviations + inline mappings
1. Apply visual operators (→ | @)
2. Apply systematic abbreviations (req, ctx, exec, ops)
3. Convert lists→inline mappings
4. Consolidate examples
5. Remove redundant words
6. Measure token reduction
7. Validate semantic preservation

After: "Analyze request→Determine path→Execute"
Savings: ~60% | Max 3-4 steps per chain

auth→authentication (security context) | val→validate (validation context) | ref→reference (@ref pattern)
Keep domain terms: authentication, authorization, delegation, prioritization
Keep critical terms: approval, safety, security
Keep technical precision: implementation, specification
- Abbreviate only when 100% clear from context
- Never abbreviate critical safety/security terms
- Maintain consistency throughout
- Document if ambiguous
key→value | key2→value2 | key3→value3
Task-to-Context Mapping:
- Writing docs → .opencode/context/core/standards/docs.md
- Writing code → .opencode/context/core/standards/code.md
- Writing tests → .opencode/context/core/standards/tests.md
Task→Context Map:
docs→standards/docs.md | code→standards/code.md | tests→standards/tests.md
~70%
Max 3-4 mappings per line for readability
"Description" (context) | "Description2" (context2)
Examples:
- "Create a new file" (write operation)
- "Run the tests" (bash operation)
- "Fix this bug" (edit operation)
Examples: "Create file" (write) | "Run tests" (bash) | "Fix bug" (edit)
~50%
- "MANDATORY" when required="true" present
- "ALWAYS" when enforcement="strict" present
- Repeated context in nested elements
- Verbose conjunctions: "and then"→"→", "or"→"|"
3-4 items when using | separator
3-4 steps when using → operator
100% clear from context
- Abbreviation creates ambiguity
- Inline mapping exceeds 4 items
- Arrow chain exceeds 4 steps
- Meaning becomes unclear
- Domain precision lost
