claude-vibe-squad: Skill for Claude Code

.claude/skills/mode-selection/SKILL.md

mode-selection is a skill for Claude Code from mtarcure/claude-vibe-squad. It costs 41 tokens per session (919 once invoked), scanned A, original, MIT.

A skill for selecting an approved operating mode before launching work, such as a project workflow or a bounty workflow.

In plain words
What is it for?
It helps choose the correct launch mode before an agent begins a project or bounty task.
Why use it?
It prevents approval of the work itself from being mistaken for approval of the workflow used to perform it.

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

mode-selection 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 4d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Mode Selection

House procedure for choosing a dispatch mode before authoring the packet. The mode is a separate operator decision from the work itself, and the wrong mode silently changes the wall, the verification contract, and the gates a lane runs under. Verify every claim here against the current scripts — do not trust this doc over the code.

  • chrono/CLAUDE.md Dispatch step 1 requires opening the chosen file under shared/modes/, stating which mode the work will run under, and waiting for the operator to agree. Hard Rule 1 forbids a mode starting without explicit consent.
  • Approving the work is not approving the mode. Measured 2026-08-21: an operator approved a bounty campaign and 34 of 38 lanes dispatched as mode: project — nobody was told. Say the mode word out loud; never infer it from "yes, go".

Both dispatch paths preserve an explicit choice

  • Generated packets use scripts/send-task.sh ... --mode project|bounty. The wrapper rejects an omitted or invalid value, writes the exact choice into frontmatter, and never supplies a default.
  • Prepared packets carry mode: project|bounty in frontmatter and dispatch with bin/send-task.sh <packet-file>, which carries the packet's own mode into the compiled contract (MODE_VALUE -> "mode").
  • The wrapper survives because it still assembles standard frontmatter, resolves lanes and review metadata, and routes through the hardened dispatcher. Retire it only if those conveniences move elsewhere; do not retain or reintroduce a mode default as its reason to exist.

Verify the mode that LANDED, never the one you intended

  • The dispatch context carries the landed mode as a real field. Read it from the exact attempt you dispatched, never from a glob — attempt ids are UUIDs, so glob order is not chronological and head -1 can hand you a previous attempt's mode after a retry:
    python3 -c 'import json,sys; a=json.load(open(sys.argv[1]))["authority"]; \
      p=a.get("mode_profile"); m=(a.get("memory_context") or {}).get("mode"); \
      print(p if p==m else f"MISMATCH profile={p} memory={m}")' <context_path>
    
    mode_profile and memory_context.mode must agree; if they disagree, stop — do not pick one.
  • A wrapper --dry-run echoes Packet mode: <mode> and derives that mode's contract. It proves the generated packet's choice but not a landed attempt; a green prepared-packet dry-run likewise does not replace the exact-attempt check.
  • If the landed mode differs from what the operator approved, stop and say so before the lane works.

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.
