Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00085 | $0.02650 |
| Opus 5 | $0.00043 | $0.01325 |
| Sonnet 5 | $0.00017 | $0.00530 |
| Haiku 4.5 | $0.00009 | $0.00265 |
Grade D, and why
worker-setup scanned grade D with 3 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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

/worker-setup
Goal
Onboard the cross-vendor worker lanes (core/infra/backends.json) one at a
time: install → authenticate → verify, with an honest cost/allocation
briefing up front. This skill never dispatches a review or a completion
check itself — that is core/infra/call-worker.sh, consumed by
/council-review and /verify-completion --second-opinion. This skill only
gets a lane from absent to healthy.
Step 0 — resolve the harness root
HR="${CLAUDE_PLUGIN_ROOT:-$PWD}"
test -f "$HR/core/infra/backends.json" || echo "worker-setup: backends registry not found at $HR — plugin users: reinstall the plugin; repo users: run this from the repo root" >&2
Stop here with that guidance if the registry does not resolve. Every command
below is relative to $HR.
Step 1 — read-only status sweep (zero paid calls)
Read $HR/core/infra/backends.json live with jq — never hardcode the
lane list, the registry is the source of truth and can grow lanes this skill
has never seen. For every backend, report one row:
| Column | How to get it |
|---|---|
| lane | the backend's key in .backends |
| vendor | .backends[$lane].vendor |
| cmd on PATH | command -v on .backends[$lane].cmd[0] |
| preflight on PATH | command -v on .backends[$lane].preflight[0] |
| config seeded | codex: ~/.codex/config.toml exists; gemini/antigravity: ~/.gemini/antigravity-cli/agent-tiers.json; grok: ~/.grok/agent-tiers.json; kiro-*: at least one ~/.kiro/agents/*.json matching a --agent in that lane's tier_args |
| cost model | from step 2's table |
| tiers | keys of .backends[$lane].tier_args |
| roles served | reverse-lookup: which .roles[*].backend (or .fallback) names this lane |
Also check once, separately: is $HOME/bin on PATH (workers/preflights
resolve from there — setup.sh's ensure_home_bin/doctor row).
This step makes zero network calls and zero CLI invocations beyond
command -v — it is safe to run unconditionally, including before the user
has decided anything.
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.

worker-setup is a skill published in the GitHub repository joymin5655/Agent (2 stars, last pushed 7d ago), licensed MIT. It adds 85 tokens to every session and 2,650 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it D with 3 findings (downloads and executes remote code, reads agent configuration directories, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
