Turn a PortPS5 ROADMAP milestone into an executable work plan (an Ouroboros seed YAML under seeds/, or a task plan for tools without Ouroboros).

  • Works in 4 steps: Read the milestone in docs/ROADMAP.md… → Draft seeds/m-.yaml with these fields → Check: every exit criterion in ROADMAP… → …
  • Starting work on a milestone M0-M6
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
  • Tasks that involve Project management

What it does

Milestone Seed is an agent skill from yuriolive/PortPS5. Turn a PortPS5 ROADMAP milestone into an executable work plan (an Ouroboros seed YAML under seeds/, or a task plan for tools without Ouroboros). Use when starting work on a milestone M0-M6.

Its SKILL.md is about 320 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: Converts decrypted PS5 game dumps into native Windows executables via binary relinking, replacement system libraries, and Vulkan. No CPU emulation. The licence is GPL-2.0.

When your agent uses it

  • Starting work on a milestone M0-M6
  • Tasks that involve Project management

Example prompts

  • “/milestone-seed”

Workflow steps

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

  1. Read the milestone in docs/ROADMAP.md (scope and exit criteria) and every spec file it touches (docs/spec/*.md → Milestones sections).
  2. Draft seeds/m-.yaml with these fields
  3. Check: every exit criterion in ROADMAP maps to exactly one acceptance criterion, and nothing extra is added.
  4. Run it

What it can do on your machine

Read from SKILL.md and the folder at commit aa7d6da. 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.

    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

Milestone Seed loads about 315 tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 142 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~315

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.

Milestone seed

  1. Read the milestone in docs/ROADMAP.md (scope and exit criteria) and every spec file it touches (docs/spec/*.md → Milestones sections).
  2. Draft seeds/m<N>-<slug>.yaml with these fields:
    • goal: one sentence stating the milestone outcome.
    • constraints: the relevant .agents/rules/* points, plus the milestone's scope boundaries (what is not in it).
    • acceptance_criteria: one per exit criterion, as outcomes rather than steps. Each has a single-line, read-only verify command. Criteria that can only be checked locally (GPU, game data) say verify: NONE and name the results JSON field that proves them.
    • context_references: the spec files and code paths.
  3. Check: every exit criterion in ROADMAP maps to exactly one acceptance criterion, and nothing extra is added.
  4. Run it:
    • Claude Code with the Ouroboros plugin: ooo run seeds/m<N>-<slug>.yaml.
    • Other tools: use the seed as the task plan and work through the acceptance criteria in order.
