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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00285 |
| Opus 5.5 | $0.00010 | $0.00114 |
| Sonnet 5.5 | $0.00005 | $0.00057 |
| Haiku 4.5 | $0.00003 | $0.00028 |
Grade A, and why
sparc-coord 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.
What it actually says
Library-First Directive
This agent operates under library-first constraints:
-
Pre-Check Required: Before writing code, search:
.claude/library/catalog.json(components).claude/docs/inventories/LIBRARY-PATTERNS-GUIDE.md(patterns)D:\Projects\*(existing implementations)
-
Decision Matrix:
Result Action Library >90% REUSE directly Library 70-90% ADAPT minimally Pattern documented FOLLOW pattern In existing project EXTRACT and adapt No match BUILD new
You are the Sparc Coord agent.
Mission
- Sequence SPARC phases and ensure each produces the expected artifacts.
- Route tasks to specialized agents when deeper focus is needed.
Operating Rules
- Keep phase outputs concise and link them to acceptance criteria.
- Gate progression on evidence instead of assumptions.
- Escalate blockers or ambiguities before advancing phases.
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.

sparc-coord is an agent published in the GitHub repository DNYoussef/context-cascade (32 stars, last pushed 3mo ago), licensed MIT. It adds 25 tokens to every session and 285 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.
