At a glance

Mandatory prelude for every role at the start of a round. An agent skill from Arch1eSUN/Arcgentic.

  • Works in 5 steps: Read state.yaml to know which round +… → Inventory locally available → Inventory project-local → …
  • Tasks that involve MCP servers
  • SKILL.md covers When to use, Rationale, Procedure and Mandatory output format, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Pre Round Scan is an agent skill from Arch1eSUN/Arcgentic. Mandatory prelude for every role at the start of a round. Inventories available skills, MCP servers, plugins, sub-agents, and external references. Outputs which tools will be used in this round and which were considered but rejected, with reasons. Use as the very first action of every role skill in an arcgentic-managed project.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/scan-checklist.md`).

It sits in Agent Workflows, covering MCP servers and Subagents. It works with Model Context Protocol. The repository describes itself as: Mechanical plan/dev/self-audit/external-audit gates for AI coding agents, with a configurable role-routing topology engine, an MCP-UI live status panel, and native-tooling Claude… The licence is MIT.

When your agent uses it

  • Tasks that involve MCP servers
  • Tasks that involve Subagents

Example prompts

  • “/pre-round-scan”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Read state.yaml to know which round + which role
  2. Inventory locally available
  3. Inventory project-local
  4. Map to round needs
  5. Document in audit/handoff § "Toolkit use"

What it can do on your machine

Read from SKILL.md and the folder at commit 8539955. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pre Round Scan loads about 633 tokens when it runs, and up to ~1.1k if it reads all its reference files. Until then it costs about 86 tokens; SKILL.md has 202 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~86
When it runs · the whole SKILL.md, loaded when a task matches
~633
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Mandatory prelude for every role at the start of a round. Inventories available skills, MCP servers, plugins, sub-agents, and external references. Outputs which tools will be used in this round and which were considered but rejected, with reasons. Use as the very first action of every role skill in an arcgentic-managed project.

Pre-round scan

When to use

EVERY role skill (plan-round, execute-round, audit-round, track-refs) invokes this as its first action, before any other reasoning. Output goes into the role's handoff/verdict document as a "§ Toolkit use" section.

Rationale

R1.4 Moirai mandate (post-NEEDS_FIX): "default: multi-agent dispatch is the path, serial is the exception". Without a pre-round scan, agents repeatedly forget that MCP servers / agency-agents / skills exist and default to from-scratch implementation. The scan is mechanical insurance.

Procedure

  1. Read state.yaml to know which round + which role
  2. Inventory locally available:
    • Skills under ~/.claude/skills/ (user-level)
    • Plugins under ~/.claude/plugins/ (cached + installed)
    • MCP servers configured in ~/.claude.json
    • Sub-agents under ~/.claude/agents/
  3. Inventory project-local:
    • Project's CLAUDE.md / AGENTS.md mandates
    • Project's references/INDEX.md (if exists) — categorized OSS clones
    • Project's tech-debt registry (if exists)
  4. Map to round needs:
    • For each round-relevant subsystem, identify candidates from inventory
    • State which will be used + why
    • State which were considered + rejected + why
  5. Document in audit/handoff § "Toolkit use"

See references/scan-checklist.md for the explicit checklist.

Mandatory output format

markdown
### Toolkit use (pre-round scan)

**Skills available + considered:**
- arcgentic:foo — used (reason)
- arcgentic:bar — rejected (reason)
- ...

**MCP servers available + considered:**
- context7 — used for {library} docs lookup
- ...

**Sub-agents available + considered:**
- backend-architect — used for BA design pass
- ...

**External references available + considered:**
- references/X — used (used-what-part)
- references/Y — rejected (reason)
- ...

Failures count

Tool failures are first-class. If context7 returns 500 and you fall back to web search, record both the attempt and the fallback. Silent degradation is a Rule 2 violation in arcgentic's discipline ledger.
