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 | $0.00018 | $0.00773 |
| Opus 5 | $0.00009 | $0.00387 |
| Sonnet 5 | $0.00004 | $0.00155 |
| Haiku 4.5 | $0.00002 | $0.00077 |
Grade A, and why
Workflow scanned grade A with 1 finding 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 11d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Quick Reference
| Topic | File |
|---|---|
| Directory layout, naming, formats | structure.md |
| Data passing between nodes | data-flow.md |

Requirements
- jq — JSON processing
- yq — YAML config parsing
- curl — HTTP requests
- flock — Lock files to prevent concurrent runs
- Secrets in macOS Keychain (
security find-generic-password)
Data Storage
- Location:
workflows/in workspace root - State:
flows/{name}/state/— cursor.json, seen.json, checkpoint.json - Logs:
flows/{name}/logs/— JSONL per run - Data:
flows/{name}/data/— intermediate files between nodes
Core Rules
1. Data Flow Pattern
Each node writes output to data/{NN}-{name}.json. Next node reads it.
curl ... > data/01-fetch.json
jq '...' data/01-fetch.json > data/02-filter.json
Breaking this pattern = nodes can't communicate.
2. Error Declaration
Every node in flow.md MUST declare:
- On error: retry(N) | fail | continue | alert
- On empty: skip | continue | fail
Undefined behavior = unpredictable workflow.
3. Lock Files
Prevent concurrent runs:
LOCKFILE="/tmp/workflow-${NAME}.lock"
exec 200>"$LOCKFILE"
flock -n 200 || exit 0
4. State Files
| File | Purpose |
|---|---|
| cursor.json | "Where did I leave off?" |
| seen.json | "What have I processed?" |
| checkpoint.json | "Multi-step recovery" |

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.
- 11d ago First seen · 103 lines · 18 tokens per session scan A 57258e310d1b
Workflow is a skill published in the GitHub repository xyva-yuangui/XyvaClaw (21 stars, last pushed 1mo ago), licensed MIT. It adds 18 tokens to every session and 773 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
