A planning skill for broad or long-running work in GoalBuddy, a task board and execution loop for coding agents. It turns a vague goal into one active task at a time, with assigned roles, progress records, and evidence that the result works.

Use it to prepare complex work, discover and sequence tasks, delegate investigation or implementation, and define tests or other proof of completion.

It gives large or stalled projects a structured path from intent to verified completion instead of relying on ad-hoc task lists.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00079	$0.05367
Opus 5	$0.00039	$0.02684

Security

Grade A, and why

goal-prep 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 9d ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/apply-receipt.mjs, scripts/check-can-stop.mjs, scripts/check-goal-state.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 391 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Goal Prep

$goal-prep (Codex) or /goal-prep (Claude Code) prepares a GoalBuddy board. It does not start execution automatically, but the board and harness-specific starter command must be shaped so the next run continues into safe execution by default.

GoalBuddy is for autonomous, long-running Codex or Claude Code work where the PM thread may need to discover the work, define tasks, sequence them, delegate them, execute them, verify them, and keep going without the human decomposing every step.

The loop is:

raw user intent -> intake compiler -> goal oracle -> local work surface -> one active task -> receipt -> proof loop -> repeat

GoalBuddy's core invariant is:

Intent -> Oracle -> Surface -> Loop -> Proof

No oracle, no serious goal. A goal oracle is the observable signal that tells the PM whether the original owner outcome is actually true yet. It may be a test suite, browser walkthrough, demo transcript, generated artifact, benchmark, source-backed answer, release check, or final human decision. Weak proof creates weak goals, so record the oracle before shaping tasks and keep testing against it until final completion.

Invocation Boundary

There are two different modes:

$goal-prep or /goal-prep: prepare intake, goal.md, state.yaml, and the starter execution commands, then stop.
Codex /goal Follow docs/goals/<slug>/goal.md. or Claude Code /goalbuddy Follow docs/goals/<slug>/goal.md.: execute the board, including Scout/Judge/Worker work.

This boundary is strict. $goal-prep is not a lightweight /goal; it is a board compiler.

This document is the prep-mode contract plus the shared board model. The execution contract lives in references/goal-execution.md next to this file; read it at the start of every Codex /goal or Claude Code /goalbuddy run. If it cannot be read, these execution invariants still hold: state.yaml is board truth; exactly one active task unless disjoint write scopes are proven; Scout and Judge tasks are read-only; Worker tasks write only inside allowed_files and run their verify commands; every completed, blocked, or escalated task gets a receipt; the goal completes only through a final Judge or PM audit that maps receipts and verification back to the original outcome (recording full_outcome_complete: true for continuous execution goals).

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.
