At a glance

Create detailed phase plan (PLAN.md) with verification loop. An agent skill from SpillwaveSolutions/agent-brain.

  • Agent Workflows work in your project
  • SKILL.md covers A. Skill Invocation, B. AskUserQuestion →… and C. Task() → spawn_agent Mapping
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Gsd Plan Phase is an agent skill from SpillwaveSolutions/agent-brain. Create detailed phase plan (PLAN.md) with verification loop

Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows. The repository describes itself as: Local-first RAG memory for AI agents: hybrid + GraphRAG search, MCP server with OAuth 2.1, plugin for Claude Code / OpenCode / Codex. The licence is MIT.

When your agent uses it

  • Agent Workflows work in your project

Example prompts

  • “/gsd-plan-phase”

What it can do on your machine

Read from SKILL.md and the folder at commit 8339623. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Gsd Plan Phase loads about 914 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 362 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~19
When it runs · the whole SKILL.md, loaded when a task matches
~914

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

<codex_skill_adapter>

A. Skill Invocation

  • This skill is invoked by mentioning $gsd-plan-phase.
  • Treat all user text after $gsd-plan-phase as {{GSD_ARGS}}.
  • If no arguments are present, treat {{GSD_ARGS}} as empty.

B. AskUserQuestion → request_user_input Mapping

GSD workflows use AskUserQuestion (Claude Code syntax). Translate to Codex request_user_input:

Parameter mapping:

  • header → header
  • question → question
  • Options formatted as "Label" — description → {label: "Label", description: "description"}
  • Generate id from header: lowercase, replace spaces with underscores

Batched calls:

  • AskUserQuestion([q1, q2]) → single request_user_input with multiple entries in questions[]

Multi-select workaround:

  • Codex has no multiSelect. Use sequential single-selects, or present a numbered freeform list asking the user to enter comma-separated numbers.

Execute mode fallback:

  • When request_user_input is rejected (Execute mode), present a plain-text numbered list and pick a reasonable default.

C. Task() → spawn_agent Mapping

GSD workflows use Task(...) (Claude Code syntax). Translate to Codex collaboration tools:

Direct mapping:

  • Task(subagent_type="X", prompt="Y") → spawn_agent(agent_type="X", message="Y")
  • Task(model="...") → omit (Codex uses per-role config, not inline model selection)
  • fork_context: false by default — GSD agents load their own context via <files_to_read> blocks

Parallel fan-out:

  • Spawn multiple agents → collect agent IDs → wait(ids) for all to complete

Result parsing:

  • Look for structured markers in agent output: CHECKPOINT, PLAN COMPLETE, SUMMARY, etc.
  • close_agent(id) after collecting results from each agent </codex_skill_adapter>
<objective>
Create executable phase prompts (PLAN.md files) for a roadmap phase with integrated research and verification.

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

Show full SKILL.md (139 more words)Show less

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. </objective>

<execution_context> @/Users/richardhightower/clients/spillwave/src/agent-brain/.codex/get-shit-done/workflows/plan-phase.md @/Users/richardhightower/clients/spillwave/src/agent-brain/.codex/get-shit-done/references/ui-brand.md </execution_context>

<context>
Phase number: {{GSD_ARGS}} (optional — auto-detects next unplanned phase if omitted)

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.
  • --reviews — Replan incorporating cross-AI review feedback from REVIEWS.md (produced by $gsd-review)
  • --text — Use plain-text numbered lists instead of TUI menus (required for /rc remote sessions)

Normalize phase input in step 2 before any directory lookups. </context>

<process>
Execute the plan-phase workflow from @/Users/richardhightower/clients/spillwave/src/agent-brain/.codex/get-shit-done/workflows/plan-phase.md end-to-end.
Preserve all workflow gates (validation, research, planning, verification loop, routing).
