Daem0n-MCP: Skill for Claude Code

.claude/skills/openspec-daem0n-bridge/SKILL.md

openspec-daem0n-bridge is a skill for Claude Code from 9thLevelSoftware/Daem0n-MCP. It costs 44 tokens per session (2,847 once invoked), scanned A, original, MIT.

A connector between OpenSpec, a tool for writing formal change proposals, and Daem0n-MCP, an AI memory system that stores searchable past outcomes. It imports project specifications into memory and feeds earlier results back into future proposals.

In plain words
What is it for?
Use it to import OpenSpec files, update the memory store, and turn archived changes into reusable lessons for future proposals.
Why use it?
It prevents the agent from treating each specification as an isolated task. Past successes, failures, and rules can inform new changes.

Token cost

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.

Security

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:

  1. Announce: "OpenSpec detected. Syncing specs to Daem0n memory..."
  2. Execute Workflow 1 (Import) automatically
  3. 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

  1. List all spec directories

    ls openspec/specs/
    
  2. For each spec, read the spec.md file

    cat openspec/specs/[name]/spec.md
    
  3. Parse requirements using these patterns:

    Pattern Extract As
    MUST, SHALL, REQUIRED rule.must_do
    MUST NOT, SHALL NOT, PROHIBITED rule.must_not
    SHOULD, RECOMMENDED pattern
    SHOULD NOT, NOT RECOMMENDED warning
    ## Purpose section pattern (overview)
  4. Create memories via remember_batch

    mcp__daem0nmcp__remember_batch(memories=[
        {
            "category": "pattern",
            "content": "[spec-name]: [overview/purpose summary]",
            "rationale": "OpenSpec specification - source of truth",
            "tags": ["openspec", "spec", "[spec-name]"],
            "file_path": "openspec/specs/[spec-name]/spec.md",
            "context": {
                "openspec_type": "spec",
                "imported_at": "[ISO timestamp]"
            }
        }
        // ... one per spec
    ])

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.
