execplan-run

execplan-run is a skill for Claude Code, Codex from CueCrux/Crux. It costs 174 tokens per session (1,891 once invoked), scanned A, original, Apache-2.0.

An execution helper for carrying an approved work plan through implementation and closeout in CueCrux, a project-tracking workflow. It handles milestones, workspaces, pull requests, checks, merges, and moving to the next milestone.

In plain words
What is it for?
Use it to claim planned work, implement one milestone at a time, run its checks, open and shepherd pull requests, merge completed work, and close the plan.
Why use it?
It closes the gap between writing a plan and actually finishing it. It keeps work ordered, checks progress, and records whether each milestone passed its required gate.

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

execplan-run scanned grade A with 1 finding 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.

How it starts

The opening of the file, as written. The whole thing — 138 lines — stays where its author put it; the contents beside it link to each section on GitHub.

ExecPlan Run

The four execplan-* skills author plans. None of them close one. That is why 63 plans sit in_progress and 25 of those have zero milestones gated (measured 2026-08-06). This skill is the execution and closeout loop.

Announce at start: "Using execplan-run — ." Then work the phases.

Two lanes

Lane Who Reads
Orchestrator — pick, check collisions, dispatch, shepherd, close the session working with the operator references/orchestrator.md
Worker — one milestone, gate to gate a worktree session or subagent references/milestone-loop.md

Default to orchestrator unless handed a specific <slug> M<n> to implement. Closeout is the orchestrator's job and it is not optional: references/closeout.md.

Mechanics live in a script, not in your context

scripts/ep does every board read, coordination call, worktree op, and PR poll and prints a compact block. Use it instead of hand-rolling curl | jq or gh loops — that is the whole token argument.

ep board [n]                        # ranked open work, already in recommended order (~650 tok)
ep preflight <slug>                 # grounding + board row + live peers + worktrees, one block
ep announce <slug> [M<n>] [paths]   # declare focus; prints overlaps. ttl 0 clears
ep worktree <repo> <slug> [branch]  # worktree off origin/main, named for the slug
ep pr open|watch|merge <dir> [...]  # push, poll checks, squash-merge
ep reap [--dry] [repo]              # delete worktrees whose branch already merged

Facts stay on MCP (store_fact / query_facts) — the script never writes them, because facts must be deliberate.

The loop

0 BOOT      once per session — banner, or ep board
1 PICK      ep board → take the FIRST entry (it is already ranked)
2 PREFLIGHT ep preflight <slug> → grounding, blockers, peers, ODs
3 CLAIM     ep announce + ep worktree + save_session
4 MILESTONE implement → test → commit → store_fact gate:M<n>   ← repeats
5 PR        ep pr open → watch → merge   (automatic; no menu unless the plan changed)
6 CLOSE     last milestone → Status flip, OD sweep, ep reap, announce ttl=0

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.
