Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00034 | $0.05447 |
| Opus 5.5 | $0.00014 | $0.02179 |
| Sonnet 5.5 | $0.00007 | $0.01089 |
| Haiku 4.5 | $0.00003 | $0.00545 |
Grade A, and why
loom-builder-complexity 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 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.
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 — 560 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Builder: Complexity Assessment and Issue Decomposition
This document covers complexity assessment, issue decomposition, and scope management for the Builder role. For the core builder workflow, see builder.md.

⚠️ --body @path Does NOT Expand — It Posts the Literal String
If you post a comment via gh issue comment / gh pr comment / gh api ... comments from a scratch file, --body @path (and gh api -f body=@path)
posts the literal string @path, not the file's contents. Full pitfall,
incident citation, and fixes:

Never Abandon Work
You must NEVER stop work on a claimed issue without creating a clear path forward.
When you claim an issue with loom:building, you are committing to ONE of these outcomes:
- Create a PR - Complete the work and submit for review
- Decompose into sub-issues - Break complex work into smaller, claimable issues
- Mark as blocked - Document the blocker and add
loom:blockedlabel
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.

loom-builder-complexity is a skill published in the GitHub repository rjwalters/kicad-tools (70 stars, last pushed today), licensed MIT. It adds 34 tokens to every session and 5,447 once invoked, about $0.0001 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 2026-09-24.
