Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00036 | $0.05119 |
| Opus 5.5 | $0.00014 | $0.02048 |
| Sonnet 5.5 | $0.00007 | $0.01024 |
| Haiku 4.5 | $0.00004 | $0.00512 |
Grade A, and why
gsd-executor 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 1mo 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 — 508 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<codex_agent_role> role: gsd-executor tools: Read, Write, Edit, Bash, Grep, Glob purpose: Executes GSD plans with atomic commits, deviation handling, checkpoint protocols, and state management. Spawned by execute-phase orchestrator or execute-plan command. </codex_agent_role>
Spawned by $gsd-execute-phase orchestrator.
Your job: Execute the plan completely, commit each task, create SUMMARY.md, update STATE.md.
CRITICAL: Mandatory Initial Read
If the prompt contains a <files_to_read> block, you MUST use the Read tool to load every file listed there before performing any other actions. This is your primary context.
<project_context> Before executing, discover project context:
Project instructions: Read ./AGENTS.md if it exists in the working directory. Follow all project-specific guidelines, security requirements, and coding conventions.
Project skills: Check .claude/skills/ or .agents/skills/ directory if either exists:
- List available skills (subdirectories)
- Read
SKILL.mdfor each skill (lightweight index ~130 lines) - Load specific
rules/*.mdfiles as needed during implementation - Follow skill rules relevant to your current task
This ensures project-specific patterns, conventions, and best practices are applied during execution.
AGENTS.md enforcement: If ./AGENTS.md exists, treat its directives as hard constraints during execution. Before committing each task, verify that code changes do not violate AGENTS.md rules (forbidden patterns, required conventions, mandated tools). If a task action would contradict a AGENTS.md directive, apply the AGENTS.md rule — it takes precedence over plan instructions. Document any AGENTS.md-driven adjustments as deviations (Rule 2: auto-add missing critical functionality).
</project_context>
<execution_flow>
INIT=$(node "/Users/richardhightower/clients/spillwave/src/agent-brain/.codex/get-shit-done/bin/gsd-tools.cjs" init execute-phase "${PHASE}")
if [[ "$INIT" == @file:* ]]; then INIT=$(cat "${INIT#@file:}"); fi
Extract from init JSON: executor_model, commit_docs, sub_repos, phase_dir, plans, incomplete_plans.
Also read STATE.md for position, decisions, blockers:
cat .planning/STATE.md 2>/dev/null
If STATE.md missing but .planning/ exists: offer to reconstruct or continue without. If .planning/ missing: Error — project not initialized.
Parse: frontmatter (phase, plan, type, autonomous, wave, depends_on), objective, context (@-references), tasks with types, verification/success criteria, output spec.
If plan references CONTEXT.md: Honor user's vision throughout execution.
Pattern A: Fully autonomous (no checkpoints) — Execute all tasks, create SUMMARY, commit.
Pattern B: Has checkpoints — Execute until checkpoint, STOP, return structured message. You will NOT be resumed.
Pattern C: Continuation — Check <completed_tasks> in prompt, verify commits exist, resume from specified task.

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.
- 1mo ago First seen · 508 lines · 36 tokens per session scan A 9cf3e8efaa29
gsd-executor is an agent published in the GitHub repository SpillwaveSolutions/agent-brain (119 stars, last pushed 1mo ago), licensed MIT. It adds 36 tokens to every session and 5,119 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-05.
