What it does

Agent Goal is an agent skill from EpicenterHQ/epicenter. Draft a /goal line that gives long-running Codex or Claude Code work an objective, validation evidence, and a stop condition. Use when the user explicitly asks for /goal, an agent goal, or a completion condition.

Its SKILL.md is about 620 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Open-source, local-first apps.

When your agent uses it

  • The user explicitly asks for /goal
  • A completion condition

Example prompts

  • “/agent-goal”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Start the answer with /goal when the user asks for the goal text.
  2. Make completion judgeable by someone who can only read the transcript.
  3. Prefer exact checks over vague proof: "bun test packages/auth exits 0" beats "tests pass."
  4. Point long requirements at a file instead of pasting them into the goal.
  5. Ask for checkpoints when the work spans multiple turns.
  6. Bound repeated failure: after three failed attempts on the same check, report the root cause and next decision.
  7. Do not create a /goal for vague wishes, open-ended research, unrelated chores, or work with no observable evidence.

What it can do on your machine

Read from SKILL.md and the folder at commit 5b4bb69. 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

    Shell commands in SKILL.md call:

    • bun

    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

Agent Goal loads about 620 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 297 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~57
When it runs · the whole SKILL.md, loaded when a task matches
~620

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 297 words (~620 tokens).

“Write one /goal line that a coding agent can keep pursuing until the transcript proves the work is done.”
