agent-collaboration

agent-collaboration is a skill for Claude Code, Codex from bradygaster/squad. It costs 22 tokens per session (440 once invoked), scanned A, original, MIT.

A shared set of working practices for software agents collaborating in the same project. It covers worktree awareness, recording decisions, requesting help, and reviewing changes.

In plain words
What is it for?
It helps agents find the repository root, read and record team decisions, ask other agents for input, and follow the project's reviewer process.
Why use it?
It reduces confusion about which project directory an agent should use and where team decisions belong. It also gives agents a consistent way to communicate responsibilities and review work.

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

agent-collaboration 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.

What it actually says

Context

Every agent on the team follows identical collaboration patterns for worktree awareness, decision recording, and cross-agent communication. These were previously duplicated in every charter's Collaboration section (~300 bytes × 18 agents = ~5.4KB of redundant context). Now centralized here.

The coordinator's spawn prompt already instructs agents to read decisions.md and their history.md. This skill adds the patterns for WRITING decisions and requesting help.

Patterns

Worktree Awareness

Use the TEAM ROOT path provided in your spawn prompt. All .squad/ paths are relative to this root. If TEAM ROOT is not provided (rare), run git rev-parse --show-toplevel as fallback. Never assume CWD is the repo root.

Decision Recording

After making a decision that affects other team members, write it to: .squad/decisions/inbox/{your-name}-{brief-slug}.md

Format:

### {date}: {decision title}
**By:** {Your Name}
**What:** {the decision}
**Why:** {rationale}

Cross-Agent Communication

If you need another team member's input, say so in your response. The coordinator will bring them in. Don't try to do work outside your domain.

Reviewer Protocol

If you have reviewer authority and reject work: the original author is locked out from revising that artifact. A different agent must own the revision. State who should revise in your rejection response.

Anti-Patterns

  • Don't read all agent charters — you only need your own context + decisions.md
  • Don't write directly to .squad/decisions.md — always use the inbox drop-box
  • Don't modify other agents' history.md files — that's Scribe's job
  • Don't assume CWD is the repo root — always use TEAM ROOT
Changes

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.
