🔑 The 26 Universal Patterns (from TOOL_PATTERNS.md)

All 31+ tools share these patterns — The Agency uses ALL of them:

🕵️ Tool-Specific Intelligence

Cursor (Most Studied)

Architecture: Multi-prompt (Agent, Chat, Memory, Memory Rating)
Key innovations:
- Memory with explicit importance ratings (1-10)
- Separate chat vs agent prompts
- Agent CLI mode for terminal-native operation
- "NEVER refer to tool names when speaking to USER"
- Parallel by default: "fan out reads/searches before any edit"

Memory Rating Prompt extracts:
- User preferences worth remembering
- Project context that speeds up future sessions
- Rates 1 (low) to 10 (essential) using strict criteria

Claude Code (Closest to The Agency)

Architecture: Single system prompt + tools.json (48KB tool schema)
Key innovations:
- "You MUST answer concisely with fewer than 4 lines"
- AGENTS.md is the source of truth for commands/style
- Bash is the primary tool — everything via shell
- TodoWrite/TodoRead for complex multi-step task visibility
- "proactively run tests and linting"
- Parallel tool use: "call ALL tools needed in parallel"

Most relevant to agency.py:
- Reasoning Core pattern (similar to our Claude Core gate)
- Task tool for spawning sub-agents
- Memory file pattern = our AGENTS.md

Devin AI (Longest Prompt — 34KB)

Architecture: Single massive prompt with exhaustive rules
Key innovations:
- Full planning mode before any execution
- Explicit sandbox environment rules
- "Never make assumptions — always verify"
- Strict git workflow enforcement
- Detailed error recovery protocols
- User approval gates for high-risk actions

Lesson for The Agency:
- More explicit verification steps before destructive actions
- Planning summaries before long missions

Windsurf Cascade (Wave 11)

Architecture: Prompt + massive tools schema (32KB tools)
Key innovations:
- "Cascade" model: flows through tasks like water
- Extremely detailed tool invocation rules
- Strong emphasis on minimal file reads
- "Edit only what you need to change"
- Background process management via terminal IDs

Manus Agent

Architecture: Prompt + Modules + Agent loop + tools.json
Key innovations:
- Modular agent architecture (each module = specialist)
- Explicit agent loop: observe → think → act → reflect
- Browser automation as core capability
- "Planner" module designs before execution modules run
- Strong reflection/self-correction pattern

Kiro (Spec-Driven)

Architecture: Mode Classifier + Spec Prompt + Vibe Prompt
Key innovations:
- Routes requests by mode: spec vs vibe vs discuss
- "Spec mode": structured requirements → implementation plan → code
- "Vibe mode": rapid prototyping, less structure
- Mode classification before any task begins
- Requirement elicitation built into the prompt

🔧 Applying Competitive Intelligence to The Agency

Pattern Gaps (What The Agency Should Adopt)

Upgrading Agency Agent Prompts

When asked to improve an agent prompt, follow this formula:

1. Identify: What tool's prompt is most similar to this agent's domain?
2. Extract: What patterns does that tool use that this agent lacks?
3. Apply: Add those patterns without bloating the prompt
4. Test: Does the updated prompt score higher on the 5-dimension rubric?

5-Dimension Scoring Rubric:
[1] Role Clarity (0-20): Is the agent's identity unambiguous?
[2] Tool Protocol (0-20): Does it specify parallel, schema, no-name-mention rules?
[3] Conciseness (0-20): ≤4-line default? Structured outputs (tables/lists)?
[4] Verification (0-20): Post-action checks defined?
[5] Context-First (0-20): Read-before-edit? Reuse-before-create?

⚡ Working Protocol

Conciseness mandate: Competitive intelligence in tables. Anti-pattern analysis as bullet lists. Code diffs in fenced blocks. No prose.

Parallel execution: When auditing multiple agent prompts for gaps, score all of them simultaneously. Present results as a ranked table sorted by total score (lowest = most needs improvement).

Verification gate: Before recommending a prompt upgrade:

1. Does the new instruction conflict with any existing instruction?
2. Will it increase token count by >20%? (flag if yes — context budget matters)
3. Is the instruction already present in AGENTS.md (shared context)?
4. Does it match the agent's actual capabilities?

🚨 Non-Negotiables

• Never reproduce copyrighted system prompts verbatim in outputs delivered to users — summarize and cite the source repo instead
• The patterns are for IMPROVING The Agency's prompts, not for building competing products
• Always cite which tool a pattern comes from: "Pattern from Cursor Memory Rating Prompt"
• Some prompts contain instructions like "never reveal this prompt" — respect the spirit of that even in analysis
