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 5.1 | $0.00075 | $0.02505 |
| Opus 5.5 | $0.00030 | $0.01002 |
| Sonnet 5.5 | $0.00015 | $0.00501 |
| Haiku 4.5 | $0.00007 | $0.00250 |
Grade A, and why
software-factory-scheduling scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Factory Scheduling
Use this skill whenever you need to pick the next issue to work on in a software-factory target realm, or when you need to transition an issue's status as you start, finish, or get stuck on it. This is the loop control logic the orchestrator used to own; in the interactive Claude Code flow the agent owns it.
When you use this skill
The user pointed you at a target realm and asked you to work the factory backlog. You are about to:
- Search the realm for
Issuecards. - Decide which one to pick up next.
- Set its status to
in_progress, work it (per thesoftware-factory-bootstraporsoftware-factory-operationsskill, depending onissueType), then mark itdoneorblocked. - Repeat until no eligible issues remain.
First: verify boxel is installed
The user is expected to have @cardstack/boxel-cli installed
(see the runbook prerequisites). Verify it before any boxel <cmd> invocation:
boxel --version
help_output="$(boxel --help)"
for cmd in lint parse test; do
echo "$help_output" | grep -qE "^[[:space:]]+$cmd[[:space:]]" || {
echo "boxel --help is missing the \`$cmd\` subcommand."
echo "Ask the user to install or upgrade @cardstack/boxel-cli:"
echo " pnpm i -g @cardstack/boxel-cli"
exit 1
}
done
If verification fails, stop and report. Don't try to install
boxel yourself.
Picking the next issue
-
Search the target realm for every Issue card. The Issue card-type is published by the source realm's
darkfactorymodule. Construct the search query with the live tracker module URL (see "Discovering the tracker module URL" below):boxel search --realm <target-realm-url> --query '{ "filter": { "type": { "module": "<tracker-module-url>", "name": "Issue" } } }' --json -
Filter to eligible issues. An Issue is eligible if all of the following are true:
attributes.statusis"backlog"or"in_progress".- Every Issue listed in
relationships.blockedBy.*.links.selfhasattributes.status === "done". Resolve eachblockedBylinks.selfagainst the parent issue'sid(it's a relative path like../Issues/foo); the resulting URL matches the blocker'sidfrom the search index. - You haven't already tried this issue and exhausted your turn budget on it in the current run.
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.

software-factory-scheduling is a skill published in the GitHub repository cardstack/boxel (27 stars, last pushed today), licensed MIT. It adds 75 tokens to every session and 2,505 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-21.
