What it costs to keep this loaded
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 | $0.00044 | $0.02847 |
| Opus 5 | $0.00022 | $0.01424 |
| Sonnet 5 | $0.00009 | $0.00569 |
| Haiku 4.5 | $0.00004 | $0.00285 |
Grade A, and why
openspec-daem0n-bridge 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 8d 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.

OpenSpec-Daem0n Bridge
Overview
This skill creates a bidirectional bridge between:
- OpenSpec: Spec-driven development with formal change proposals
- Daem0n-MCP: AI memory system with semantic search and outcome tracking
The feedback loop:
OpenSpec specs ──────► Daem0n patterns/rules
▲ │
│ ▼
Future specs ◄────── Past outcomes/failures
Auto-Detection
On session start, after get_briefing():
Check if openspec/ directory exists in the project root:
ls openspec/specs/ 2>/dev/null
If OpenSpec detected AND specs not yet imported:
- Announce: "OpenSpec detected. Syncing specs to Daem0n memory..."
- Execute Workflow 1 (Import) automatically
- Report summary of imported specs and rules
How to check if already imported:
recall(topic="openspec", tags=["spec"], limit=1)
If results exist with recent timestamps, skip import.
Workflow 1: Import Specs to Memory
Triggers:
- Auto: OpenSpec directory detected on first session
- Manual: "sync specs to memory", "import openspec", "refresh openspec"
Steps
-
List all spec directories
ls openspec/specs/ -
For each spec, read the spec.md file
cat openspec/specs/[name]/spec.md -
Parse requirements using these patterns:

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.

openspec-daem0n-bridge is a skill published in the GitHub repository 9thLevelSoftware/Daem0n-MCP (73 stars, last pushed 29d ago), licensed MIT. It adds 44 tokens to every session and 2,847 once invoked, about $0.0002 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.
