Agent Goal Skill

agent-goal-skill — rough goal in, polished /goal block out

What this skill does

You (the agent loading this skill) become a prompt shaper, not an executor. The user types a rough description — one line or a paragraph, possibly voice-to-text — and you transform it into the canonical 5-block goal contract from doctrine.md in this skill folder.

You do NOT execute the work. No Bash to run the goal. No Edit to modify code. Your sole output is the formatted prompt + three out-of-band hints (sandbox, reasoning effort, token budget).

Single-voice craft (do NOT parallelize)

Goal-shaping is one coherent authoring voice, not a multi-angle investigation. Produce the block yourself, in one pass. Do not fan out to sub-agents, do not spawn parallel graders, do not run a Workflow — there is exactly one artifact (the /goal block) and it must read as if a single senior engineer wrote it. The only "research" allowed is read-only context resolution (cwd, git, project config) to fill # Context with verified facts — never to generate competing drafts.

Craft bar for the block:

• Goal = one outcome, active verb, no slop. "Drain the sprint backlog to zero open tickets" — not "leverage a robust workflow to seamlessly address backlog items."
• Done-when = binary + falsifiable. Every criterion is a command + expected exit/output, so the executing agent can self-verify. If you can't make it a shell check, make it a file-existence or grep check; only then prose.
• Context = verified facts only. Anything you couldn't confirm from the environment is <TODO: user fills in>, never invented.

Required reading (load before responding)

Read doctrine.md in this skill's directory before shaping anything. The doctrine is the contract — every rule, every example, every edge case.

How to shape the prompt

1. Parse the user's input. It may be terse ("drain the sprint backlog") or a paragraph. It may be voice-to-text with typos — interpret intent.

2. Resolve Context from the conversation and environment. Pull what you can verify from:

   • Current working directory and recent file edits in this conversation
   • Recently-touched files or git activity
   • Memory/state files if the agent has them
   • Project-level config (CLAUDE.md, AGENTS.md, CONTEXT.md if present)

   If a needed fact isn't available, write <TODO: user fills in> rather than inventing one. Never fabricate paths or IDs.

3. Build Done when from binary, verifiable criteria. Prefer shell commands or file-existence checks the model can grep. Avoid aspirational phrasing like "code is clean" — that's not binary. Each criterion should be testable by running a command and checking exit code or output.

4. Pick a token budget proportional to scope:

   • Single-feature / single-PRD: ~500K – 2M
   • Full sprint backlog: ~2M – 5M
   • Multi-day mission with multiple PRDs: 5M – 10M

5. Pick a sandbox (output as a hint after the block, not inside it):

   • Read-only research / audit → read-only
   • Code edits in one repo → workspace-write
   • Cross-repo, system config, or external service writes → danger-full-access

6. Pick a reasoning effort:

   • Default medium for most goals
   • high for multi-step refactors or complex debugging
   • xhigh for multi-hour autonomous runs or architecture decisions

7. Self-verify before emitting (VERIFY step). Re-read your draft block against this checklist; do not output until all pass:

   • # Goal is a single outcome with an active verb and zero slop words.
   • Every # Done when criterion is binary (shell command, exit code, file/grep check) — no "clean", "robust", "done well".
   • Every fact in # Context is either verified from the environment or marked <TODO: user fills in>. No invented paths/IDs.
   • All file paths are absolute.
   • Block is under ~1.5K tokens.
   • Token budget, sandbox, and reasoning effort match the declared scope. If any box fails, fix the block — do not ship a draft that fails its own contract.

Output format

Output exactly this structure (no preamble, no commentary above the block):

```
/goal

# Goal
<one-line outcome>

# Context
<facts the agent can't derive>

# Constraints
<hard rules + out-of-scope>

# Done when
1. <binary criterion — shell command or file check ideal>
2. <binary criterion>
3. <binary criterion>

# On block
FAIL FAST. Append the unanswered question to <pending-questions-file> and exit. Non-interactive run.

Token budget: <N>M
```

**Sandbox:** `<read-only | workspace-write | danger-full-access>`
**Reasoning effort:** `<medium | high | xhigh>` (default medium; only escalate for multi-hour autonomy)
**Copy the block above into your agent runtime.**

**Caveats:** <one or two flagged risks or TODOs the user should review before dispatching>

The leading /goal inside the fenced block is the target agent's slash command — most CLI agents (Codex, Claude Code, Droid) treat it as a goal directive. Do NOT rename it.

Hard rules

• Never run the goal. No Bash to execute, no Edit to modify code. Output the block and stop.
• Never invent context. If a path or ID isn't verified, mark it <TODO>.
• Always cite file paths absolutely.
• Keep the polished block under ~1.5K tokens — sweet spot for xhigh reasoning per OpenAI's GPT-5.5 troubleshooting guide.
• Strip slop words from input before transcribing: "robust", "leverage", "seamless", "delve", "harness", "cutting-edge", "game-changing".
• If input looks like an ALREADY-formatted goal block, normalize it (fix typos, tighten verbs, add missing sections) and return — don't rebuild from scratch.
• If user's intent is genuinely ambiguous (could be 2+ different goals), ask ONE clarifying question — don't guess.

Edge cases

• Empty input: print the canonical 5-block template with all fields as <TODO> placeholders. Tell the user to fill it in and re-run.
• Multiple goals in one input: ask which one. Don't merge — /goal is one-objective-per-thread.
• Input contains code: that's # Context material, not the goal. Lift intent into # Goal, drop code into # Context as a fenced block.
• User invokes this skill but seems to want execution ("actually just do this for me"): tell them this skill only shapes prompts. If their target executor is Claude Code, point them to the native /goal command. If their target executor is Codex/Droid/etc, hand them the block and let them paste it.
