ralplan

ralplan is a skill for Claude Code from jcwleo/oh-no-harness. It costs 47 tokens per session (7,836 once invoked), scanned A, original, MIT.

An implementation-planning workflow for work whose requirements are already understood. It uses evidence from the code repository to produce a reviewed plan and an execution profile.

In plain words
What is it for?
Use it to plan multi-step, cross-file changes or work involving important design choices. It prepares an approved plan for later execution.
Why use it?
It removes guesswork from large, risky, or architecture-sensitive changes. It also keeps planning separate from writing production code.

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

ralplan 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 10d 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.

Ralplan

Ralplan converts approved requirements plus repository evidence into one reviewed plan and Ralph execution profile. It never implements production code and writes only under .oh-no/. Plan-Reviewer depth and instance count are selected by the execution risk, not applied as an unconditional tax.

Invariants

R1. Requirements direction is user-owned. A role proposal that changes the
    Direction Contract is `requested-direction-change: yes` and needs explicit
    user approval; do not incorporate a requested direction change without
    explicit approval. An approved change starts a new planning run.
R2. The plan body is Planner-owned. Plan-Reviewer reviews and blocks; it MUST
    NOT produce a replacement plan.
R3. Plan-Reviewer reviews the exact Planner draft (id + body), not a recap:
    architecture pass, then quality-gate pass, in one dispatch.
R4. APPROVE freezes the exact reviewed Planner draft. Non-blocking findings
    are optional follow-ups and cause no mutation or dispatch; a body change
    required before approval is blocking and yields ITERATE.
R5. On ITERATE, Planner classifies every blocker before mutating the draft or
    assigning a new draft id (disposition-before-mutation).
R6. Review runs exactly once (Review v1) per planning run. REJECT escalates
    immediately. An all-accepted ITERATE yields exactly one final Planner
    revision v2 with no further review.
R8. Every blocker names a basis, exact draft pointer, material consequence,
    and smallest sufficient correction. Preference, future-proofing, and
    optional stronger proof are non-blocking.
R9. Roles are sequential — Analyst -> Planner -> Plan-Reviewer. Review
    topology is risk-selected: STANDARD and ordinary THOROUGH each dispatch ONE
    required full-role Plan-Reviewer. Only the named THOROUGH paired-review
    trigger selects one perspective-diverse pair and the platform's escalated
    diversity (cross-host on Codex); THOROUGH alone never does.
R10. Active semantic risk selects mode and cost; category words and host
     capability alone never escalate.
R15. The Active plan contract is compiled once before Planner draft v1, and
     the identical block goes to Planner and every reviewer instance.
     Reviewer missing-field blocking is limited to its active rows.
R16. Recorded snapshot state authorizes transitions; unrecorded in-memory
     conclusions do not.

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.

ralplan is a skill published in the GitHub repository jcwleo/oh-no-harness (11 stars, last pushed 1mo ago), licensed MIT. It adds 47 tokens to every session and 7,836 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 2026-08-30.
