Orchestrates multi-day execution of complex tasks through milestones.

  • Works in 4 steps: Load and Validate State → Milestone Execution Loop → Parallel Milestone Execution → …
  • The user says long run
  • SKILL.md covers Core Principle, Hard Gates, When To Use and When NOT To Use, plus 11 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Long Run is an agent skill from tmdgusya/engineering-discipline. Orchestrates multi-day execution of complex tasks through milestones. Each milestone goes through plan-crafting, run-plan (worker-validator), and review-work phases with checkpoint/recovery. Runs autonomously end-to-end — no per-milestone approval gates; escalates to the user only on failures. Triggers when the user says "long run", "start long run", "execute milestones", or "run all milestones".

Its SKILL.md is about 5.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Product & Project Management, covering Project management. The repository describes itself as: SKILL for engineering-discipline.

When your agent uses it

  • The user says long run
  • Execute milestones
  • Run all milestones

Example prompts

  • “long run”
  • “start long run”
  • “execute milestones”
  • “/long-run”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Load and Validate State
  2. Milestone Execution Loop
  3. Parallel Milestone Execution
  4. Completion

What it can do on your machine

Read from SKILL.md and the folder at commit 137dead. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    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

Long Run loads about 5.4k tokens when it runs. Until then it costs about 102 tokens; SKILL.md has 2,611 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~102
When it runs · the whole SKILL.md, loaded when a task matches
~5.4k

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: warnings

    port and proceed directly to execution. Do not wait for approval.

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 2,611 words (~5,383 tokens).

“Orchestrates multi-day execution of complex tasks through a milestone pipeline. Each milestone passes through plan-crafting → run-plan → review-work with checkpoints between milestones for recovery from interruptions.”
