phase-dev-plan.template

phase-dev-plan.template is a command for coding agents from evan043/claude-cli-advanced-starter-pack. It costs 0 tokens per session (5,729 once invoked), scanned A, original, MIT.

A command template that turns a feature or bug description into a phased development plan. Phases are groups of work completed in sequence, with support for organizing work under roadmaps and epics.

In plain words
What is it for?
Use it to plan small, medium, or large changes, and to place the plan under a parent roadmap or epic.
Why use it?
It breaks complex development into smaller stages, making dependencies and progress easier to track before implementation begins.

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

phase-dev-plan.template 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 646 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Codex Runtime Compatibility

This prompt was authored for Claude-style slash workflows. In Codex runtime, adapt tool calls as follows:

  • AskUserQuestion => ask the user directly in chat.
  • WebSearch/WebFetch => use available web tools (search_query, open, find) and cite links.
  • Read/Write => use shell/filesystem tools in this workspace.
  • Claude-only MCP calls (for example Playwright MCP names) => use available equivalents or clearly state fallback.
  • Keep intent and output format identical; only adapt execution mechanics.

description: Create phased development plans with 95%+ success probability options:

  • label: "Small (1-2 phases)" description: "Quick feature or bug fix"
  • label: "Medium (3-4 phases)" description: "Standard feature implementation"
  • label: "Large (5+ phases)" description: "Complex multi-system changes"

Phased Development Plan Generator

Create comprehensive, executable development plans that maximize success probability.

NEW EPIC-HIERARCHY ARCHITECTURE:

  • Supports parent roadmap context via --parent-roadmap flag
  • Supports parent epic context via --parent-epic flag
  • Includes parent_context in PROGRESS.json
  • Reports PHASE_DEV_COMPLETE to parent when all phases complete
  • Uses src/phase-dev/completion-reporter.js for parent notification

🚨 MANDATORY FILE CREATION - DO NOT SKIP

CRITICAL: Every phase-dev-plan MUST create ALL of these files. Skipping ANY file is a failure.

Exploration Documentation (REQUIRED FIRST - Step 2)

Before creating PROGRESS.json, you MUST create these 6 files in .claude/exploration/{slug}/:

File Purpose Required
EXPLORATION_SUMMARY.md Overview + statistics ✅ YES
CODE_SNIPPETS.md Extracted code examples ✅ YES
REFERENCE_FILES.md File paths + line numbers ✅ YES
AGENT_DELEGATION.md Agent assignments per task ✅ YES
PHASE_BREAKDOWN.md Full phase/task detail ✅ YES
findings.json Machine-readable data ✅ YES

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.

phase-dev-plan.template is a command published in the GitHub repository evan043/claude-cli-advanced-starter-pack (61 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 5,729 tokens. 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.
