| 1 | # Decision Council |
| 2 | |
| 3 | $ARGUMENTS |
| 4 | |
| 5 | Evaluate a decision from 4 distinct perspectives using parallel sub-agents, then synthesize a weighted recommendation. |
| 6 | |
| 7 | ## Usage |
| 8 | |
| 9 | ``` |
| 10 | /council [decision question or proposal to evaluate] |
| 11 | ``` |
| 12 | |
| 13 | ## What This Command Does |
| 14 | |
| 15 | 1. **Parses** the decision question from user input |
| 16 | 2. **Gathers** codebase context relevant to the decision |
| 17 | 3. **Spawns** 4 parallel sub-agents — each analyzing from a different perspective |
| 18 | 4. **Synthesizes** all perspectives into a structured recommendation with decision matrix |
| 19 | |
| 20 | ## MANDATORY: You MUST use the Agent tool |
| 21 | |
| 22 | **DO NOT analyze the decision yourself.** Your job is to parse the question, spawn 4 sub-agents in parallel via the `Agent` tool, and synthesize their outputs. If you attempt to provide all perspectives inline, you have failed. |
| 23 | |
| 24 | ## Process |
| 25 | |
| 26 | ### 1. Parse the Decision |
| 27 | |
| 28 | Extract from the user's input: |
| 29 | |
| 30 | - **The proposal** — what is being considered |
| 31 | - **The alternatives** — what the options are (if not stated, infer the implicit alternative: status quo) |
| 32 | - **The context** — what project/codebase/situation this applies to |
| 33 | |
| 34 | If the question is too vague to evaluate, ask ONE clarifying question before proceeding. |
| 35 | |
| 36 | ### 2. Gather Context |
| 37 | |
| 38 | Before spawning agents, quickly scan the codebase for relevant context: |
| 39 | |
| 40 | - Current tech stack, dependencies, patterns in use |
| 41 | - Existing code related to the decision area |
| 42 | - Configuration, infrastructure, or architectural choices already made |
| 43 | |
| 44 | Include this context in each sub-agent prompt so perspectives are grounded in reality. |
| 45 | |
| 46 | ### 3. Spawn 4 Sub-Agents in Parallel (REQUIRED) |
| 47 | |
| 48 | Call the `Agent` tool **4 times in a single response** — all agents MUST launch in the same message to run in parallel. |
| 49 | |
| 50 | | Agent | Role | Directive | |
| 51 | |-------|------|-----------| |
| 52 | | **Advocate** | Case FOR | Present the strongest case FOR the proposal. Find evidence, benefits, success stories. Reference relevant code/patterns in the codebase. Be persuasive but honest. | |
| 53 | | **Critic** | Case AGAINST | Present the strongest case AGAINST. Find risks, hidden costs, failure modes, alternatives that might be better. Be thorough but fair. | |
| 54 | | **Pragmatist** | Trade-offs | Evaluate practical trade-offs: implementation cost, timeline, team capacity, maintenance burden, migration risk, operational complexity. Ground estimates in the actual codebase size and patterns. | |
| 55 | | **User-Proxy** | User impact | Consider end-user and customer impact: UX changes, downtime during migration, performance implications, breaking changes, adoption friction, documentation needs. | |
| 56 | |
| 57 | Each agent prompt MUST include: |
| 58 | |
| 59 | 1. The original decision question |
| 60 | 2. The codebase context gathered in step 2 |
| 61 | 3. The specific perspective this agent owns |
| 62 | 4. Instruction to search the codebase for supporting evidence |
| 63 | 5. Constraint: 200-400 words, concrete evidence over abstract arguments |
| 64 | |
| 65 | ### 4. Synthesize |
| 66 | |
| 67 | After all 4 agents complete, combine their outputs into the structured format below. Do NOT simply concatenate — identify agreements, contradictions, and conditional factors across perspectives. |
| 68 | |
| 69 | ## Output Format |
| 70 | |
| 71 | ```markdown |
| 72 | ## Decision Council: [Question] |
| 73 | |
| 74 | ### Advocate (FOR) |
| 75 | [Summary of arguments for — key benefits and evidence] |
| 76 | |
| 77 | ### Critic (AGAINST) |
| 78 | [Summary of arguments against — key risks and alternatives] |
| 79 | |
| 80 | ### Pragmatist (TRADE-OFFS) |
| 81 | [Practical considerations — cost, timeline, complexity] |
| 82 | |
| 83 | ### User-Proxy (USER IMPACT) |
| 84 | [End-user perspective — UX, performance, breaking changes] |
| 85 | |
| 86 | ### Synthesis |
| 87 | **Recommendation:** [FOR / AGAINST / CONDITIONAL] |
| 88 | **Confidence:** [HIGH / MEDIUM / LOW] |
| 89 | **Key condition:** [Primary factor that would change the recommendation] |
| 90 | |
| 91 | **Where perspectives agree:** [Common ground across agents] |
| 92 | **Where perspectives conflict:** [Key disagreements and why] |
| 93 | |
| 94 | ### Decision Matrix |
| 95 | | Factor | Weight | FOR score (1-5) | AGAINST score (1-5) | |
| 96 | |--------|--------|-----------------|---------------------| |
| 97 | | Technical merit | [H/M/L] | [score] | [score] | |
| 98 | | Risk | [H/M/L] | [score] | [score] | |
| 99 | | Cost | [H/M/L] | [score] | [score] | |
| 100 | | Timeline | [H/M/L] | [score] | [score] | |
| 101 | | User impact | [H/M/L] | [score] | [score] | |
| 102 | | **Weighted total** | | **[total]** | **[total]** | |
| 103 | ``` |
| 104 | |
| 105 | ## Rules |
| 106 | |
| 107 | - Each sub-agent must search the codebase for relevant evidence — no purely abstract arguments |
| 108 | - Sub-agents must be honest within their role — the Advocate should acknowledge weaknesses, the Critic should acknowledge strengths |
| 109 | - Keep each perspective to 200-400 words — density over length |
| 110 | - The synthesis must add value beyond summarizing — identify the decisive factor |
| 111 | - If the decision is clearly one-sided after analysis, say so — don't manufacture false balance |
