run

run is a skill for Claude Code from stellarshenson/claude-code-plugins. It costs 12 tokens per session (1,040 once invoked), scanned A, original, MIT.

A command for running an autobuild orchestrator, a tool that coordinates repeated software improvement cycles. It checks that the required toolkit is installed and current before starting.

In plain words
What is it for?
It helps launch structured autonomous iterations for improving a codebase.
Why use it?
It avoids running with an unavailable or outdated toolkit and keeps the orchestrator from modifying the caller's project setup.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions .claude-plugin; names the AskUserQuestion tool.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

run 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 20d 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.

Autobuild - Run Orchestrator

Load and execute the autobuild skill for autonomous iteration orchestration.

Pre-flight install (MANDATORY, no asking)

Before invoking orchestrate, always run:

python3 -m pip install --user --upgrade stellars-claude-code-plugins 2>&1 | tail -1
LIB=$(python3 -c "import importlib.metadata as m;print(m.version('stellars-claude-code-plugins'))" 2>/dev/null) || { echo "FATAL: toolkit unavailable"; exit 1; }
PLUG=$(grep -m1 '"version"' "${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json" 2>/dev/null | cut -d'"' -f4)
OLDER=$(printf '%s\n%s\n' "$LIB" "$PLUG" | sort -V | head -1)
[ -n "$PLUG" ] && [ "$LIB" != "$PLUG" ] && [ "$OLDER" = "$LIB" ] && { echo "STALE: library $LIB older than plugin $PLUG - refusing to run on an outdated CLI; re-run the upgrade"; exit 1; }
echo "toolkit $LIB"

Run the CLI without touching the caller's project. The gate above puts it on PATH, so the bare command name is the whole invocation. uv run instead resolves whatever project the working directory sits in and writes uv.lock and .venv into it, so if you reach for uv pass --no-project (uv run --no-project <cli> ...) - it skips project discovery, leaves the tree untouched and still finds the same PATH binary. --no-sync and --frozen are not substitutes; both still create .venv.

The upgrade always runs - a stale-but-importable install is exactly the failure this gate prevents, and the reinstall also repairs a stale shim on PATH whose package is uninstalled in the active Python.

Startup Sequence

When the user asks to run an improvement cycle, execute these skills IN ORDER before starting the orchestrator:

  1. program-writer - Generate PROGRAM.md from user's objective. Ask clarifying questions about scope, constraints, exit conditions. Do NOT proceed until user approves the program.

  2. benchmark-writer - Generate BENCHMARK.md from the approved PROGRAM.md. Define score formula, direction (minimize/maximize), checklist sections, evaluation instructions. Do NOT proceed until user approves the benchmark.

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.

run is a skill published in the GitHub repository stellarshenson/claude-code-plugins (4 stars, last pushed today), licensed MIT. It adds 12 tokens to every session and 1,040 once invoked, about $0.0000 per session on Opus 5.5. 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.
