gsd:plan-phase

A planning command that creates a detailed PLAN.md file for a project phase. It can research the topic, check the plan, and use a requirements file.

In plain words
What is it for?
Use it to plan a development phase, close gaps found during verification, or build a plan from acceptance criteria.
Why use it?
It reduces the work of turning a phase goal into an ordered, checked plan. You can skip research or checking when they are not needed.

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

gsd:plan-phase 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 yesterday.

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

Default flow: Research (if needed) → Plan → Verify → Done

Orchestrator role: Parse arguments, validate phase, research domain (unless skipped), spawn gsd-planner, verify with gsd-plan-checker, iterate until pass or max iterations, present results.

<execution_context> @./.claude/get-shit-done/workflows/plan-phase.md @./.claude/get-shit-done/references/ui-brand.md </execution_context>

Flags:

  • --research — Force re-research even if RESEARCH.md exists
  • --skip-research — Skip research, go straight to planning
  • --gaps — Gap closure mode (reads VERIFICATION.md, skips research)
  • --skip-verify — Skip verification loop
  • --prd <file> — Use a PRD/acceptance criteria file instead of discuss-phase. Parses requirements into CONTEXT.md automatically. Skips discuss-phase entirely.

Normalize phase input in step 2 before any directory lookups.

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.
