fr-plan

fr-plan is a skill for Claude Code, Codex from derio-net/super-fr. It costs 36 tokens per session (1,523 once invoked), scanned A, original, MIT.

A collaborative planning workflow that breaks a software change into phases and records the plan as files in the project.

In plain words
What is it for?
Use it to create phase-based implementation plans, connect them to a written specification, and document the work in a plans folder.
Why use it?
It turns a broad request into an organized sequence of implementation steps that another developer or coding agent can follow and review.

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

fr-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 7d 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

fr-plan

Produce implementation plans through collaborative dialogue. Conversational parts stay here; mechanical parts delegate to the fr plan CLI.

Announce at start: "I'm using fr-plan to create the implementation plan."

Format (v2 plan-as-folder)

A plan is a directory under docs/superpowers/plans/<slug>/ containing:

  • _meta.yaml — schema_version, plan slug, spec ref, target_repo, vk_version, created date, optional rework metadata (parent_plan, prior_rework, origin_items).
    • spec ref notation: a same-repo spec is a plain repo-relative path (docs/superpowers/specs/<file>.md). A spec that lives in another repo MUST use the cross-repo form <owner>/<repo>:<path-in-that-repo> (e.g. derio-net/frank:docs/superpowers/specs/<file>.md). Without the owner/repo: prefix, fr apply's reachability gate treats it as a missing same-repo file and refuses to dispatch. fr plan self-review warns when a same-repo-form spec doesn't resolve locally (#248).
  • _prose.md — the human-readable narrative. Tooling never parses this; it's for humans (and the implementing agent).
  • NN.yaml (one file per phase, two-digit zero-padded: 01.yaml, 02.yaml, …, 99.yaml) — phase header, tasks, steps, and per-step state. Per-phase files prevent merge conflicts when parallel branches tick different phases. Phases are numbered from 1: 01.yaml is the first phase; 00.yaml (phase 0) fails parse — fr plan create rejects it pre-flight.

Every step id follows P<n>.T<n>.S<n> (phase number, task number, step number). The renderer / observer / diff / apply chain depends on this shape.

Procedure

  1. Read context (recent commits, existing plans, spec file).
  2. Confirm scope. Decompose if too large.
  3. Propose 2-3 approaches with tradeoffs. Recommend one.
  4. Present plan structure section by section, get approval.
  5. Scaffold the plan folder:
    fr plan create --slug <YYYY-MM-DD-slug> --target-repo <owner/repo> \
        --spec docs/superpowers/specs/<spec-file>.md \
        --phases-file <phases.yaml> \
        --prose-file <prose.md>
    
    fr plan create ALSO appends a row to the spec's ## Implementation Plans table — there is no separate spec-index step.
  6. Iterate on the prose / per-phase yaml via the Edit tool.
  7. Run self-review: fr plan self-review <plan-dir>.
  8. Hand off for execution:
    • fr apply <plan-dir> — render → observe → diff → preview (default dry-run). Add --yes to actually create / update GitHub Issues.
    • The implementing agent uses fr pickup <plan-dir> --phase N to receive the phase scope as markdown.

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.

fr-plan is a skill published in the GitHub repository derio-net/super-fr (1 stars, last pushed yesterday), licensed MIT. It adds 36 tokens to every session and 1,523 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
