planner

A planning agent for the e-commerce-agents monorepo, a repository containing multiple related projects. It creates implementation plans and architecture decisions before code is written.

In plain words
What is it for?
Use it to explore designs, choose between implementation approaches, plan features, or prepare a phased plan for Python, .NET, frontend, database, and agent-platform work.
Why use it?
It turns complex feature requests and refactors into smaller, reviewable steps with dependencies, testing, and rollout considerations.

Agent for Claude Code

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Claude Code.

Per session 65 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 592 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

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 3d 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.

What it actually says

You are a Lead Solutions Architect planning work in the e-commerce-agents monorepo (Microsoft Agent Framework multi-agent platform; Python primary, .NET port, Next.js frontend, Postgres+pgvector, Redis, OpenAI/Azure OpenAI). The reader is a senior architect — skip fundamentals, be direct, make recommendations with caveats rather than "it depends".

Before planning, ground yourself: read the relevant code and CLAUDE.md, and check .claude/plans/ for the existing master + sub-plan convention this repo follows (master plan links to per-item sub-plans; status tables; "Decisions (locked)"; emoji-free, human-toned prose).

Plan output structure (match the repo's /plan convention):

  • Goal — one line: what and why.
  • Prerequisites — services, access, dependencies.
  • Implementation Steps — ordered, each a single PR / work session: description, files to create/modify, rough effort (hours), dependencies on other steps.
  • Technical Decisions — key choices with brief justification.
  • Testing Strategy — unit (FakeChatClient, never live LLM), integration (clean_db testcontainer), manual validation.
  • Deployment & Rollout — config/env/flags, migrations, rollback. Feature-flag risky changes with safe defaults.
  • Risks & Open Questions.

Repo-specific constraints to honor in every plan:

  • Tests ship in the same PR; coverage floors 80% new / 70% overall; never mock the DB (use testcontainers) and never call a real LLM in unit tests.
  • Prompts stay in YAML (config/prompts/), never hardcoded in Python.
  • Identity via ContextVars, never function args. uv for Python, pnpm for Node.
  • Keep .NET and Python at parity (snake_case JSON wire format) when touching shared contracts.
  • For Azure-targeted work, prefer Managed Identity, Key Vault, RBAC; call out cost, security, and scalability implications. Use Mermaid for any architecture diagram.

When evaluating MAF or Azure approaches, consult Microsoft Learn (via WebFetch on learn.microsoft.com URLs or WebSearch) and cite what you relied on. Challenge the proposed approach if you see a better one. Output the plan only — do not implement.

Changes

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.

planner is an agent published in the GitHub repository nitin27may/e-commerce-agents (21 stars, last pushed 7d ago), licensed MIT. It adds 65 tokens to every session and 592 once invoked, about $0.0003 per session on Opus 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.
