done

A workflow for archiving finished, skipped, or abandoned features and missions in a Done.md history file. It can also browse past work and recover deleted mission content using Git commit identifiers.

In plain words
What is it for?
Use it to record completed or dropped work, review previously finished items, and restore the content of deleted mission files.
Why use it?
It keeps active planning files uncluttered while preserving a record of what happened and why.

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

done 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 2d 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 — 119 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Done

Archive completed work to Done.md and browse past accomplishments.

Config Preamble

Before any operation, locate the PlanKit folder and read its config:

  1. Check if PlanKit/ exists in the project root. If not, check plan-kit/.
  2. Read .config.json from the PlanKit folder to get the naming convention.

Determine file path:

  • Done: PlanKit/Done.md or plan-kit/done.md

If Done.md doesn't exist, create it with just # Done as content.

Archive Scenarios

Other PlanKit skills trigger these scenarios by loading this skill and specifying which one applies. When loaded, find the matching scenario and follow its instructions.

Scenario 1: Mission Completed (or Dropped)

Triggered by the mission-breakdown skill after a mission file is deleted.

Input from calling skill: mission name, mission letter, feature name, feature number, file path, status (✅ completed or 🛑 dropped), reason (for dropped only), PR numbers (if known).

  1. Get the deletion commit SHA: git log -1 --format=%h -- "path/to/deleted/file"
    • This finds the commit that last touched the file (the deletion commit)
  2. Read Done.md
  3. Find or create the version section:
    • Look for ## vX.Y matching the feature's roadmap version
    • If it doesn't exist, create it: ## vX.Y — Subtitle (YYYY-MM-DD →)
    • Start date = today if this is the first entry for this version
    • End date left blank (filled when version is released)
  4. Find or create the feature subsection:
    • Look for ### ... NNN-FeatureName under the version section
    • If it doesn't exist, create it with the feature's one-line description from the Roadmap
    • Don't set the feature-level status marker yet (it's set when the feature is fully complete)
  5. Add the mission line:
    • Format: - ✅ X-MissionName · plan: \SHA`` (for completed)
    • Format: - 🛑 X-MissionName · plan: \SHA` — reason` (for dropped)
    • Append · PR #N if PR numbers were provided
  6. Write Done.md

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
