A command-line tool for starting and managing separate coding-agent workers, called builders, in isolated workspaces. It also handles their protocols, status, messages, and scheduled tasks.

Spawning builders for issues or custom tasks, resuming existing workers, checking their status, and managing their workspaces or scheduled jobs.

It reduces the manual work of setting up parallel coding sessions and helps keep their changes separated.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00094	$0.03149
Opus 5.5	$0.00038	$0.01260
Sonnet 5.5	$0.00019	$0.00630
Haiku 4.5	$0.00009	$0.00315

Security

Grade C, and why

afx scanned grade C with 2 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 14d 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.

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:

git status — worktree must be clean (or use --force)
Commit specs/plans first — builders branch from HEAD and can't see uncommitted files
--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 ships with it

6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

afx is a skill published in the GitHub repository cluesmith/codev (297 stars, last pushed 2d ago), licensed Apache-2.0. It adds 94 tokens to every session and 3,149 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
