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 | $0.00014 | $0.01491 |
| Opus 5.5 | $0.00006 | $0.00596 |
| Sonnet 5.5 | $0.00003 | $0.00298 |
| Haiku 4.5 | $0.00001 | $0.00149 |
Grade A, and why
write-prd 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 1mo 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 — 201 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/write-prd - Brief + Constitution -> PRD
/write-prd is the PRD-level clarification loop. It resolves high-impact ambiguity before /spec-init builds the SDD route map and /prd decomposes the PRD into Memory Bank L1-L3 artifacts.
0) Input sources
Read the current PRD source. Accept any one of these as the source input:
.memory-bank/analysis/product-brief.md- explicit PRD source text or file provided by the user
- existing
prd.mdor.memory-bank/prd.mdwhen present and being normalized/clarified
Read as optional context when present and relevant:
.memory-bank/constitution.md.memory-bank/analysis/brainstorming/BR-*.md.memory-bank/product.md.memory-bank/requirements.md.memory-bank/glossary.md.memory-bank/invariants.md.memory-bank/spec-index.md.memory-bank/contracts/*.memory-bank/states/*.memory-bank/runbooks/*.memory-bank/testing/*- user-provided context in
$ARGUMENTS
If no Product Brief, explicit PRD source text/file, or existing prd.md / .memory-bank/prd.md is available, stop and ask for /brief or explicit PRD source text.
If the Constitution is missing, stop and ask for /constitution or explicit permission to create the PRD without a Constitution gate.
1) Constitution gate
Compare the PRD source and optional context against .memory-bank/constitution.md.
If the PRD requires changing the Constitution, add this section to .memory-bank/prd.md and stop unless the user explicitly confirms the amendment path:
## Constitution Amendment Candidates
### Candidate 1
- Current principle:
- Conflict:
- Proposed amendment:
- Rationale:
Do not weaken, reinterpret, or silently override the Constitution.
2) Draft PRD
Create or update .memory-bank/prd.md with this frontmatter:
---
description: Product Requirements Document.
status: draft
type: prd
clarification_status: pending
constitution_checked: true

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.
- 1mo ago First seen · 201 lines · 14 tokens per session scan A 32288db9e5fc
write-prd is a command published in the GitHub repository mrvladd-d/memobank (56 stars, last pushed 4mo ago), licensed MIT. It adds 14 tokens to every session and 1,491 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 2026-08-30.
