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.

SkillSpector: 1 finding, up to medium
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 →
- medium Rogue Agent · line 248 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.
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 | $0.00046 | $0.03452 |
| Opus 5 | $0.00023 | $0.01726 |
| Sonnet 5 | $0.00009 | $0.00690 |
| Haiku 4.5 | $0.00005 | $0.00345 |
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.
How it starts
The opening of the file, as written. The whole thing — 379 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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'."
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.
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.

bundle-builder is a skill published in the GitHub repository magnus919/agent-skills (74 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 3,452 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 2026-09-05.
