bundle-builder

bundle-builder is a skill for Claude Code from magnus919/agent-skills. It costs 46 tokens per session (3,452 once invoked), scanned A, original, MIT.

A workflow tool that turns saved interview or observation notes into an Agent Skills bundle, a directory of files an agent can load and use. It creates the bundle only when required workflow details are present.

In plain words
What is it for?
Use it to generate a loadable skill package from recorded workflow stages, branches, entry points, and completion conditions, with an optional task board.
Why use it?
It removes the repetitive work of assembling skill files, documentation, a manifest, and workflow maps by hand. It also stops when key information is missing rather than producing an incomplete bundle.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

bundle-builder 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 2d 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.

Bundle Builder — Workflow Synthesis Engine

This sub-skill is loaded after the interviewer (active mode) or observer (passive mode) achieves convergence. It reads the accumulated workflow state from memory and generates an output bundle directory.

Input

All workflow-architect:state:* memory entries. Read them all at once:

Read: workflow-architect:state:entry_points
Read: workflow-architect:state:phases
Read: workflow-architect:state:branching
Read: workflow-architect:state:pain_points
Read: workflow-architect:state:exit_criteria

If any required fields are missing (entry_points, phases, branching, exit_criteria), abort with a clear message about what's missing.

Output Structure

The bundle is written to ~/.hermes/skills/<category>/<bundle-name>/ with this layout:

<bundle-name>/
├── SKILL.md                # *** UMBRELLA ENTRY POINT *** — makes the bundle
│                           # loadable via skill_view() and discoverable by
│                           # the agent's skill scanner on trigger keywords.
│                           # CRITICAL: without this, the bundle is invisible.
├── README.md               # Summary of this bundle
├── manifest.yaml           # Skill-to-trigger mapping
├── skills/
│   ├── entry-skill.md      # One per discovered phase
│   ├── phase-two.md
│   └── ...
├── decision-map.md         # Mermaid flowchart
├── AGENTS.md               # Agent loading instructions for this bundle
├── kanban/
│   └── board-definition.yaml  # Only if kanban is appropriate
└── references/
    └── generated-from.md   # Metadata about how this bundle was created

The SKILL.md umbrella is not optional. Without it, individual sub-skills may exist on disk but the agent's skill scanner has no entry point to match trigger keywords against. The umbrella is how the agent discovers and enters the bundle.

Bundle naming

Ask the user for a bundle name at the start of synthesis:

"Before I generate the bundle — what should I call it?
Something short, lowercase with hyphens, like 'my-triage-workflow'
or 'dev-sprint-routine'."

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
