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

01-plan 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 1mo 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.

What it actually says

Skill: plan

Turn a gathered source into an implementation plan and its phase files. Never writes code.

Actions

# Action Role Input
01 gather Collect and restate the source user request
02 explore Read the codebase for projection, rules, feasibility gathered source
03 wireframe Sketch a screen at low fidelity, frontend only source + explore context
04 plan Break into phases, write the plan and phase files explore output + wireframe

Run them in order, 01 → 04. The plan is the culmination. Skip 03 when there is no UI. Before running an action, read its file in actions/, not only the table or assets.

Once the plan and its phase files are written, and only then, run:

echo "aidd:step-end aidd-dev:01-plan"

This is the one thing about a step nothing else can supply. No host reports when a skill's work finished — a skill call's own result comes back in a tenth of a second, which is the dispatch, not the completion — so a measurement that never hears this ends the step at the next pause and credits planning with one turn out of however many it took. The framework repository documents the run journal this writes into, in aidd_docs/runs/README.md.

References

  • references/wireframe-conventions.md: how to draw the ASCII wireframe a screen needs.
  • references/plan-status.md: the plan lifecycle status values and who writes each.

Assets

  • assets/plan-template.md: the plan.md scaffold.
  • assets/phase-template.md: the per-phase scaffold.
Files

What ships with it

8 files 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.
