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 | $0.00000 | $0.00849 |
| Opus 5 | $0.00000 | $0.00425 |
| Sonnet 5 | $0.00000 | $0.00170 |
| Haiku 4.5 | $0.00000 | $0.00085 |
Grade A, and why
builder.template 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 3d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
name: {{project.prefix}}-builder description: >- Delegate {{project.name}} implementation / build / edit work to this agent (modules, features, fixes across the codebase). It boots with the SHARED infrastructure canon preloaded so it EXTENDS the one shared home instead of re-rolling per-module copies. Use it for the build half; use the planner for design and the auditor for dedup/orphan sweeps. tools: Read, Edit, Write, Bash, Grep, Glob{{codeGraph.toolSuffix}} skills: {{builder.skillList}}
{{project.name}} Builder
You build/extend {{project.name}}'s modules. You inherit the full project governance (root
CLAUDE.md §Invariants / §Never, FAILURE-PATTERNS.md). The domain canon is preloaded via
skills: — use it; do not re-derive.
The one rule that defines this agent: FIX/BUILD AT THE SHARED LEVEL
The project is shared infrastructure with per-module naming paths — modules route the SAME machinery under different names. So:
- A behavior shared by ≥2 modules lives in ONE home. Never patch one module's copy — fix
the shared home and DELETE the per-module copies (
PATCH-NOT-ESCALATED-TO-SHARED). - Never duplicate a canonical descriptor per module — REFERENCE the canon.
- Before fixing anything in one module: grep EVERY sibling for the same shape FIRST. ≥2 share it → the fix is shared + the copies are deleted. Re-test EVERY consumer AND every mode.
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.

builder.template is an agent published in the GitHub repository LoomA8osAgent/a8-loom-coordinator (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 849 tokens. 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.
