afx

afx is a skill for Claude Code, Codex from cluesmith/ci-channel. It costs 94 tokens per session (1,265 once invoked), scanned A, original, MIT.

A command-line tool for starting and managing separate coding workers, workspaces, and scheduled jobs. It supports different work protocols and can resume existing workers.

In plain words
What is it for?
Use it to start a worker for an issue or ad-hoc task, provide context files, choose a work protocol, create a separate worktree, check or resume work, and manage scheduled jobs.
Why use it?
It removes the need to remember the tool’s exact command options and helps keep parallel coding work isolated. This reduces errors when starting or continuing work on issues.

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

afx 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 5d 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.

Agent Farm CLI

afx spawn

Spawns a new builder in an isolated git worktree.

afx spawn [number] [options]

The ONLY flags that exist:

Flag Description
--protocol <name> Protocol: spir, aspir, air, bugfix, tick, maintain, experiment. Required for numbered spawns.
--task <text> Ad-hoc task (no issue number needed)
--shell Bare Claude session
--worktree Bare worktree session
--amends <number> Original spec number (TICK only)
--files <files> Context files, comma-separated. Requires --task.
--no-comment Skip commenting on the GitHub issue
--force Skip dirty-worktree and collision checks
--soft Soft mode (AI follows protocol, you verify)
--strict Strict mode (porch orchestrates) — this is the default
--resume Resume builder in existing worktree
--no-role Skip loading role prompt

There is NO -t, --title, --name, or --branch flag. The branch name is auto-generated from the issue title.

Examples:

afx spawn 42 --protocol spir           # SPIR builder for issue #42
afx spawn 42 --protocol aspir          # ASPIR (autonomous, no human gates)
afx spawn 42 --protocol air            # AIR (small features)
afx spawn 42 --protocol bugfix         # Bugfix
afx spawn 42 --protocol tick --amends 30  # TICK amendment to spec 30
afx spawn 42 --protocol spir --soft    # Soft mode
afx spawn 42 --resume                  # Resume existing builder
afx spawn --task "fix the flaky test"  # Ad-hoc task (no issue)
afx spawn 42 --protocol spir --force   # Skip dirty-worktree check

Pre-spawn checklist:

  1. git status — worktree must be clean (or use --force)
  2. Commit specs/plans first — builders branch from HEAD and can't see uncommitted files
  3. --protocol is required for numbered spawns

afx send

Sends a message to a running builder.

afx send [builder] [message]
Flag Description
--all Send to all builders
--file <path> Include file content
--interrupt Send Ctrl+C first
--raw Skip structured formatting
--no-enter Don't press Enter after message

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.
