arnesto: Skill for Claude Code

.cursor/skills-cursor/goal/SKILL.md

goal is a skill for Claude Code, Cursor from saski/arnesto. It costs 12 tokens per session (979 once invoked), scanned A, original, Unlicense.

A persistent objective that a coding agent continues working toward until the requested outcome is complete.

In plain words
What is it for?
It is for tracking multi-step development work and verifying its required results.
Why use it?
It removes the need to restate a long-running task after each turn.

Skill for Claude CodeCursor

Written for Claude Code and Cursor: disable-model-invocation in frontmatter, but also installed under .cursor/. Also seen: names the TodoWrite tool.

This is saski/arnesto's own configuration. It tells Claude Code and Cursor how to work on arnesto itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything arnesto configures →

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

goal 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.

How it starts

The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Goal

Use the same durable, tool-driven flow in local and cloud environments.

Parse

Accept /goal <objective>.

  • If the objective is empty, show Usage: /goal <objective>.
  • There is no deadline, token budget, or turn budget. A goal continues until it is complete.
  • If the request leads with a time limit such as 30m or 2h, say plainly that time-limited goals are not supported yet, then create the goal without one rather than folding the limit into the objective.
  • "Every" describes recurring work and belongs to /loop, not /goal.

Start

  1. Restate the objective clearly, including every explicit deliverable or required evidence you will verify against the repo.
  2. Call CreateGoal exactly once with the objective. Do not create goal files manually or retry creation.
  3. If creation fails, report that no goal was armed. Goal state lives in conversation state; ordinary file tools may keep optional scratchpads, but continuation does not require them.
  4. Perform the first concrete unit of work immediately in this turn; do not stop after planning or creating the goal.

Guidelines

Continuation behavior:

  • This goal persists across turns. Ending this turn does not require shrinking the objective to what fits now.
  • Keep the full objective intact. If it cannot be finished now, make concrete progress toward the real requested end state, leave the goal active, and do not redefine success around a smaller or easier task.
  • Temporary rough edges are acceptable while the work is moving in the right direction. Completion still requires the requested end state to be true and verified.

Work from evidence: Use the current working tree and external state as authoritative. Previous conversation context can help locate relevant work, but inspect the current state before relying on it. Improve, replace, or remove existing work as needed to satisfy the actual objective.

Progress visibility: If TodoWrite is available and the next work is meaningfully multi-step, use it to show a concise plan tied to the real objective. Keep the plan current as steps complete or the next best action changes. Skip planning overhead for trivial one-step progress, and do not treat a plan update as a substitute for doing the work.

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.
