What it does
Lifecycle Check is an agent skill from MillenniumDawn/Millennium-Dawn. Audit a country branch against the focus tree lifecycle checklist (focus tree, ideas, decisions, OOB, characters, loc, namelists, AI, game rules, graphics, changelog), reporting done/missing/partial per item. Use when asked if a country's content is complete or review-ready, e.g. "/lifecycle-check UKR".
Its SKILL.md is about 980 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 Development, covering Changelog and release notes. The repository describes itself as: Millennium Dawn and it's codebase. The licence is CC-BY-SA-4.0.
When your agent uses it
- Asked if a countrys content is complete
- Tasks that involve Changelog and release notes
Example prompts
- “s content is complete or review-ready, e.g.”
- “/lifecycle-check”
What it can do on your machine
Read from SKILL.md and the folder at commit 5821281. 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:
git
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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
Lifecycle Check loads about 977 tokens when it runs. Until then it costs about 80 tokens; SKILL.md has 303 words of instructions outside code blocks.
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

- lifecycle-check
- description
- Audit a country branch against the focus tree lifecycle checklist (focus tree, ideas, decisions, OOB, characters, loc, namelists, AI, game rules, graphics, changelog), reporting done/missing/partial per item. Use when asked if a country's content is complete or review-ready, e.g. "/lifecycle-check UKR".
Syntax: /lifecycle-check [TAG]. Without a TAG, infer it from the most frequent
country prefix in git diff origin/main...HEAD --name-only.
Read docs/src/content/resources/focus-tree-lifecycle-checklist.md first.
Checks
Mark each item Done, Missing, or Partial (the file exists but looks like a stub).
Drafting cannot be checked from files. Remind the user that draft approval comes before coding.
Coding
| Item | How to check |
|---|---|
| Focus tree file | common/national_focus/05_TAG.txt exists and is non-empty |
| Focus tree rewards | Count completion_reward blocks vs focus count to spot stubs |
| National ideas | common/ideas/TAG.txt exists; grep for idea blocks |
| National decisions | common/decisions/TAG*.txt (or under categories/) exists |
| History file updated | history/countries/TAG*.txt in branch diff, or exists and non-trivial |
| OOB file | history/units/TAG_*.txt exists |
| Character file | common/characters/TAG.txt has a general or field_marshal block |
| Party localisation | localisation/english/ contains a file with TAG. ideology keys |
| Focus localisation | localisation/english/MD_focus_TAG_l_english.yml non-empty |
| Ideas localisation | localisation/english/ file with TAG_idea_ or TAG_spirit_ keys |
| Decisions localisation | localisation/english/ contains a file with decision keys for TAG |
| Unit namelists | TAG name entries in common/units/names/ or names_divisions/ |
| Investment/Influence AI | common/ai_strategy/TAG*.txt has investment or influence entries |
| Game rules | common/game_rules/ contains a rule referencing TAG |
| Scripted localisation | common/scripted_localisation/ file with TAG entries (if used) |
Graphics
| Item | How to check |
|---|---|
| Focus icons | Every focus has icon =; flag placeholders like goal_unknown |
| Idea icons | Grep the ideas file for picture = |
| Leader portraits | gfx/leaders/TAG/ exists and contains at least one .dds file |
Polish and completion
| Item | How to check |
|---|---|
| Spell-check | Manual review needed |
| error.log clear | Requires an in-game test |
| Playtest | Requires manual confirmation |
| Code compliance | Recommend /content-review and /audit |
| Changelog entry | Grep Changelog.txt for the TAG or country name |
| Authors updated | Confirm manually against docs/src/content/misc/authors.md |
Output
One line per item, grouped by phase, with [✓], [✗], [~], or [?], the item name,
and the path or reason. End with a count of done, missing, partial, and manual-only.
Flag any missing item required before lead review: focus tree, OOB, localisation,
changelog.
