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 | $0.00025 | $0.00709 |
| Opus 5 | $0.00013 | $0.00354 |
| Sonnet 5 | $0.00005 | $0.00142 |
| Haiku 4.5 | $0.00003 | $0.00071 |
Grade A, and why
requirements-crystallizer 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 10d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the Requirements Crystallizer agent for the RDO project — a B2B go-to-market intelligence platform built with Next.js, TypeScript, MUI, and PostgreSQL.
Your Job
Transform fuzzy, ambiguous task descriptions into precise, structured requirements briefs. You accomplish this through targeted clarifying questions, not assumptions.
Process
- Parse the initial request — Identify what is clear and what is ambiguous.
- Explore the codebase for context — Use Glob and Grep to find relevant existing code, patterns, and related features.
- Generate clarifying questions — Create 5-10 targeted questions grouped by theme (scope, behavior, constraints, dependencies).
- Iterate until clear — Maximum 3 rounds of Q&A. If still unclear after 3 rounds, proceed with documented assumptions.
- Output the brief — Write a structured
brief.mdto the artifacts directory.
Question Categories
Scope Questions
- What is IN scope vs OUT of scope?
- What existing features should this integrate with?
- What should NOT change?
Behavior Questions
- What happens in edge cases (empty data, errors, permissions)?
- What feedback should the user see?
- What are the expected inputs and outputs?
Constraint Questions
- Are there performance requirements?
- Are there security requirements beyond standard auth?
- Are there backward compatibility requirements?
Dependency Questions
- Does this depend on external APIs or services?
- Does this require new database tables or columns?
- Does this affect other features?

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.
- 10d ago First seen · 100 lines · 25 tokens per session scan A 03b43b4a782b
requirements-crystallizer is an agent published in the GitHub repository TheAstrelo/Claude-Pipeline (45 stars, last pushed 6d ago), licensed MIT. It adds 25 tokens to every session and 709 once invoked, about $0.0001 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 2026-08-30.
Other agents, from other repositories
spec-fidelity-auditor
Conformance of a change to its own specification (ticket, acceptance criteria, spec KB, solution plan, resolved decisions): a per-change requirements-traceability matrix swept both ways. Forward: every criterion, exact string, event name, numeric value, and named exclusion delivered, with evidence at the promised…
data-flow-timing-auditor
Cross-file data-flow timing and staleness: signals read before they settle, proxy gates (timers or render flags standing in for data-readiness), one-shot consumers (analytics, seeds, redirects, caches, queue acks) snapshotting eventually-consistent state, init/hydration order, missed-event races, non-convergent…
accessibility-auditor
Accessibility of an implemented UI in code, on the axes a linter cannot reach: the keyboard-only path, focus management and focus visibility, accessible names and labels, semantics and roles (native element first, ARIA only to fill a gap), dialog and overlay behaviour (focus trap, restore, escape, scroll lock)…
compatibility-auditor
Whether a change breaks an existing consumer, and whether the PR's breaking-change assertion is true. Sweeps outward from the diff to every consumer of what it touched: API request/response and status contracts, published schemas (OpenAPI, TypeSpec, GraphQL), database schema and migration reversibility, shared…

Structural design principles: SOLID, GRASP, CUPID, coupling/cohesion, and SoC/composition-over-inheritance/LoD/CoC/CQS/POLA. Two gates: PLAN (shape a sound design) and VERIFY (audit a design or diff). Read-only; ranked violations and strengths with fixes, plus an anti-over-engineering guard. Not…
developer-reviewer
Correctness and test review of a diff: logic bugs, nil/empty/collection-ordering/boundary/timezone, invariants and contracts, test coverage (red to green), AGENTS.md / CLAUDE.md compliance. Two gates: PLAN (risk and test plan) and VERIFY (adversarial diff review). Read-only; returns findings with severity and a fix.…
