new-plan

A planning guide that turns a request or issue into an execution-ready development plan. It requires scope, acceptance criteria, dependencies, validation steps, and risk controls.

In plain words
What is it for?
Reading issue details and comments, checking related merge requests and issues, defining the affected modules, and planning implementation and verification.
Why use it?
It reduces hidden assumptions by making the requested outcome, related work, and proof of completion explicit before implementation starts.

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

new-plan 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 2d 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.

The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.

New Plan

Purpose

Turn a request into a plan that can be executed without hidden assumptions.

Required Inputs

  • user request or issue link
  • affected modules and stack context
  • architecture and policy constraints
  • delivery constraints (deadline/dependency)

Quando o input inclui uma issue do tracker, o agente deve consumir todos os campos antes de planear:

GitLab (default):

# 1. Body completo + metadata (labels, milestone, assignees, state, dates, web_url)
glab issue view <N> --output json

# 2. Todos os comentários/notas (decisões, feedback, mudanças de scope)
glab issue view <N> --comments

# 3. MRs já vinculados à issue (trabalho existente, branches abertas)
glab api "projects/:id/issues/<N>/related_merge_requests" 2>/dev/null || true

# 4. Issues relacionadas (parent, blocker, linked — dependências e fronteiras)
glab api "projects/:id/issues/<N>/links" 2>/dev/null || true

Exceção web/your-github-project (GitHub):

gh issue view <N> --json number,title,body,state,labels,milestone,assignees,url,comments
gh api "repos/{owner}/{repo}/issues/<N>/timeline" --jq '.[] | select(.event=="cross-referenced")' 2>/dev/null || true

Campos obrigatórios a usar no plano:

Campo Uso no plano
description (body) Requisitos, scope, AC — base do work breakdown
notes / comments Decisões posteriores, mudanças de scope, contexto técnico
labels Prioridade, tipo de trabalho, área/módulo, flags (Blocked, needs-research)
milestone Ciclo de entrega — informar deadline/constraints
assignees Responsável — contacto para dúvidas
related MRs Trabalho já feito — ajustar plano ao estado real
linked issues Dependências, bloqueadores, parent — mapear para Dependencies section

Não planear com base apenas no título ou resumo verbal do utilizador quando existe issue no tracker.

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.

new-plan is a skill published in the GitHub repository Joaonic/agentkit (2 stars, last pushed 3mo ago), licensed MIT. It adds 24 tokens to every session and 737 once invoked, about $0.0001 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 2026-08-31.
