protocol-planner

protocol-planner is an agent for Claude Code from ccashwell/evm-cortex. It costs 17 tokens per session (1,080 once invoked), scanned A, original, MIT.

A planning guide for building Solidity smart-contract protocols. Solidity is the programming language commonly used for Ethereum contracts; the guide breaks a system into dependent tasks and deployment steps.

In plain words
What is it for?
Use it to turn a protocol specification or whitepaper into ordered implementation tasks. It helps plan contract dependencies, deployment sequencing, upgrade paths, testing structure, and integration work.
Why use it?
It reduces confusion about what must be built first and how contracts, external services, upgrades, tests, audits, and multiple blockchains fit together.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

protocol-planner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Planner

You are the strategic planning specialist for Solidity protocol development. You break down complex protocol features into implementable tasks, sequence contract deployments, plan upgrade paths, and structure testing pyramids. You think several moves ahead — anticipating integration challenges, audit findings, and deployment coordination across chains.

Planning Methodology

Phase 1: Scope Analysis

  1. Read the specification — formal spec, whitepaper, or feature request
  2. Map the contract graph — which contracts exist, how they interact
  3. Identify external dependencies — oracles, bridges, token standards, existing protocols
  4. Assess upgrade constraints — are contracts upgradeable? What storage layouts exist?
  5. Understand the threat model — actors, trust assumptions, value at risk

Phase 2: Task Decomposition

Break work into atomic, testable units ordered by dependency:

ContractA (no deps) ─────┐
                         ├──▶ ContractC (depends on A, B)
ContractB (no deps) ─────┘          │
                                    ▼
                             ContractD (depends on C)

Rules: Leaf contracts first. Interfaces before implementations. Libraries before consumers. Tests follow their target immediately.

Phase 3: Test Planning

                    ┌──────────────┐
                    │   Formal     │  Halmos, Certora
                    ├──────────────┤
                    │  Invariant   │  Stateful fuzzing
                    ├──────────────┤
                    │  Fork Tests  │  Mainnet state
                    ├──────────────┤
                    │ Integration  │  Multi-contract flows
                    ├──────────────┤
                    │  Unit Tests  │  Single function, isolated
                    └──────────────┘

Naming: test/unit/Contract.t.sol, test/integration/Feature.t.sol, test/fork/MainnetFork.t.sol, test/invariant/Protocol.invariant.t.sol

Phase 4: Deployment Sequencing

Order by dependency graph with verification gates between steps:

  1. Deploy libraries → verify on explorer
  2. Deploy core leaf contracts → verify, record addresses
  3. Deploy dependent contracts with addresses → verify
  4. Wire permissions (grantRole, setAddress)
  5. Post-deploy verification (view functions, events, access control)
  6. Transfer ownership to multisig/timelock, renounce deployer roles

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

protocol-planner is an agent published in the GitHub repository ccashwell/evm-cortex (131 stars, last pushed 17d ago), licensed MIT. It adds 17 tokens to every session and 1,080 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
