gsd:list-phase-assumptions

A command that lists the assumptions Claude is making about how a project phase should be approached. It presents the assumptions for discussion before planning begins.

In plain words
What is it for?
Use it to check a phase against the roadmap, review assumptions about the work, and decide whether to provide context, plan the phase, or correct the assumptions.
Why use it?
It helps catch misunderstandings early, before they shape the phase plan.

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:list-phase-assumptions 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.

Origin

This is a copy

94% identical to gsd:list-phase-assumptions — 6 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Purpose: Help users see what Claude thinks BEFORE planning begins - enabling course correction early when assumptions are wrong. Output: Conversational output only (no file creation) - ends with "What do you think?" prompt

<execution_context> @./.claude/get-shit-done/workflows/list-phase-assumptions.md </execution_context>

Project state and roadmap are loaded in-workflow using targeted reads.

<success_criteria>

  • Phase validated against roadmap
  • Assumptions surfaced across five areas
  • User prompted for feedback
  • User knows next steps (discuss context, plan phase, or correct assumptions) </success_criteria>
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.
