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 | $0.00061 | $0.02810 |
| Opus 5.5 | $0.00024 | $0.01124 |
| Sonnet 5.5 | $0.00012 | $0.00562 |
| Haiku 4.5 | $0.00006 | $0.00281 |
Grade A, and why
update-arch 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 2mo 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.

Update Architecture Documentation
Refresh and expand architecture documentation, updating stale content and expanding stub files with detailed analysis.
Inputs: Existing docs/PROJECT-ARCH.md and stub files
Outputs: Updated docs/PROJECT-ARCH.md and expanded docs/PROJECT-ARCH/*.md sub-files
NPL Dependencies
Load NPL definitions before proceeding using the NPLLoad MCP tool:

Design Philosophy
incremental : Only regenerate sections that are stale or incomplete — preserve manual edits
expand-stubs
: Transform stub files from /init-project-fast into full detailed documentation
drift-detection : Identify discrepancies between documentation and current codebase
preserve-intent : Maintain architectural decisions and rationale added by humans
Phase 1: Analyze Current State
1.1 Inventory Existing Documentation
Check current documentation state:
inventory = {
main_file: check_exists("docs/PROJECT-ARCH.md"),
sub_files: glob("docs/PROJECT-ARCH/*.md"),
stubs: [],
detailed: [],
missing: []
}
for file in inventory.sub_files:
if contains(file, "Stub generated by init-project"):
inventory.stubs.append(file)
else:
inventory.detailed.append(file)
# Expected sub-files per spec
expected = ["layers.md", "domain.md", "patterns.md", "infrastructure.md"]
for expected_file in expected:
if expected_file not in inventory.sub_files:
inventory.missing.append(expected_file)
1.2 Determine Update Mode
| Condition | Mode | Action |
|---|---|---|
| No PROJECT-ARCH.md exists | full-init |
Run /init-project instead |
| Stubs exist | expand |
Expand stubs to detailed files |
| All detailed, possible drift | refresh |
Validate and update stale sections |
| User requests specific section | targeted |
Update only requested sections |
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.

update-arch is a command published in the GitHub repository noizu-labs-ml/NoizuPromptLingo (13 stars, last pushed 10d ago), licensed MIT. It adds 61 tokens to every session and 2,810 once invoked, about $0.0002 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 2026-09-04.
