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 | $0.00059 | $0.00945 |
| Opus 5 | $0.00030 | $0.00473 |
| Sonnet 5 | $0.00012 | $0.00189 |
| Haiku 4.5 | $0.00006 | $0.00094 |
Grade A, and why
software-factory 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 6d 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 — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Factory
Software Factory is an AI-native SDLC method for connecting product intent, technical intent, and implementation work in one traceable workflow.
This portable skill is for writing Software Factory records and executing Work Orders headlessly in any repository. It does not assume access to a hosted Software Factory service, private repository automation, or repository-specific review skills. When project tools are available, use them; otherwise, use the files and templates in this skill as the execution system of record.
Records
Requirements
Requirements describe the system from an external perspective.
- Product Overview Documents capture durable product-wide why and what: business problem, current state, product description, success metrics, technical requirements, and other framing.
- Feature Requirements Documents capture localized feature intent with user stories and acceptance criteria. User stories state who needs what and why; acceptance criteria define testable behavior.
Read guides/requirements-writing-guide.md when writing or revising requirements.
Blueprints
Blueprints describe the system from an internal perspective.
- Container Blueprints document separately deployable or runnable units and their runtime boundaries.
- Component Blueprints document reusable system capabilities. Structured
componentblocks define runtime nodes; relationship paragraphs describe data, contracts, and control flow. - Feature Blueprints compose Component Blueprints and feature-specific components to satisfy a Feature Requirements Document.
Read guides/blueprint-writing-guide.md when writing or revising blueprints. During implementation, follow referenced Blueprints—including @… mentions and links resolved via MCP—before coding so the full component graph is understood.
Delivery
Work Orders describe delivery intent: implementable scope, exclusions, connected requirements, connected blueprints, and acceptance-test expectations.

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 is a skill published in the GitHub repository 8090-inc/software-factory-plugin (7 stars, last pushed 2mo ago), licensed MIT. It adds 59 tokens to every session and 945 once invoked, about $0.0003 per session on Opus 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 2026-08-31.
