execute-round

execute-round is a skill for Claude Code from Arch1eSUN/Arcgentic. It costs 65 tokens per session (1,030 once invoked), scanned A, original, MIT.

A workflow for carrying out a pre-planned development round from start to finish. It runs four handoff stages: administration, design, coding with review, and a final state check.

In plain words
What is it for?
Use it to implement a planned round in an arcgentic project, including the required design, development, code review, software-engineering review, and self-audit steps.
Why use it?
It removes the need to coordinate each project stage manually or remember which role should act next. It also requires a written handoff so implementation follows an agreed plan.

    Skill enumerates or reads other installed skills. Access to other skills' SKILL.md files or the skills directory reveals prompt instructions, capabilities, and secrets that should be invisible to peer skills.
    Fix: Remove all code or instructions that list or read other skills' files or directories. Skills should operate independently; cross-skill access is a privilege escalation.

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

execute-round 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.

How it starts

The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

execute-round

Orchestrates the 4-commit chain for an arcgentic round per spec § 4.2.3. Reads the planned handoff (from plan-round skill or hand-authored), then executes Phase 1-4 via the arcgentic Python CLI.

When to invoke

  • User says "let's execute round R{N}" or "run the 4-commit chain for the handoff at ..."
  • User runs /execute-round <round_name> slash command
  • A handoff doc exists at docs/superpowers/plans/... and dev work is ready to start

Prerequisites

Requires the arcgentic CLI:

  • Stable: pipx install arcgentic
  • Dev: cd toolkit && pip install -e ".[dev]"

Requires a planned handoff doc — run /plan-round first if missing.

V1 projects must resolve the session-mode gate before implementation. If project.session_mode.mode is already present in .agentic-rounds/state.yaml, use it and do not ask again:

arcgentic session-mode recommend --round=$ROUND --handoff=$HANDOFF_PATH
arcgentic session-mode prompt --round=$ROUND --handoff=$HANDOFF_PATH --mode=multi-session --role=developer

Inputs

Parse from $ARGUMENTS:

  • round_name (e.g. "R10-L3-aletheia")
  • handoff_path (defaults to most recent docs/superpowers/plans/{date}-{round}-handoff.md)
  • --dry-run flag (optional; skip all commits and pushes)

Workflow

When invoked:

  1. Verify the handoff doc exists at handoff_path.
  2. Shell out:
    arcgentic execute-round-impl --round=$ROUND --handoff=$HANDOFF_PATH [--dry-run]
    
  3. The CLI orchestrates 4 phases:
    • Phase 1 — Entry-admin commit: commit handoff + state-row updates
    • Phase 2 — BA design pass: dispatch ba-designer → write design doc → commit
    • Phase 3 — Dev body: dispatch developer → run pre-audit quality gates (mypy / pytest / ruff) → inline CR step → inline SE step (MANDATE #20: NO BA design in SE brief) → commit
    • Phase 4 — State refresh + self-audit handoff: compose self-audit handoff doc with stable artifact/fixed-anchor facts → run arcgentic audit-check --strict-extended → write → commit

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.
