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 | $0.00126 | $0.00895 |
| Opus 5 | $0.00063 | $0.00447 |
| Sonnet 5 | $0.00025 | $0.00179 |
| Haiku 4.5 | $0.00013 | $0.00089 |
Grade A, and why
true-polymorph 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.

True Polymorph
Transform a system so completely that the original form is gone — no rollback, no undo.
What This Skill Does
In D&D, True Polymorph is the permanent transformation — the target becomes something fundamentally different, and if held long enough, the change is irreversible. Unlike Polymorph (temporary disguise or adaptation), True Polymorph means the old identity is gone. The real-world version is irreversible system transformation: rewriting a service from Python to Rust so thoroughly the Python version cannot be recovered, migrating from SQL to a graph database with no backward-compatible schema, or restructuring an organization so completely that the old org chart is not just outdated but nonsensical. True Polymorph is the point of no return. In this grimoire, True Polymorph is treated as a hybrid spell with a prototype delivery profile. Canonical reference input: True Polymorph (spell).
When To Use
- A system, stack, or organization must become something fundamentally different and the old form will not be maintained.
- Backward compatibility or rollback is no longer a real requirement.
- The transformation changes identity, interfaces, or structure so completely that dependents must migrate too.
Prerequisites
- No extra runtime dependencies beyond Hermes Agent and the normal toolset for this session.
Procedure
- Restate the target, the success condition, and any no-touch boundaries before taking action.
- Define the current form, target form, and what exactly makes the transformation irreversible.
- Run or review a reversible trial transformation first to surface hidden failure modes.
- Inventory every dependent system, contract, and operator workflow that assumes the old form.
- Plan the cutover so dependents migrate before the original interface disappears.
- Return the irreversible transformation plan with go or no-go criteria and explicit point-of-no-return conditions.
- Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly.
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.

true-polymorph is a skill published in the GitHub repository Hmbown/Wizards-of-the-Ghosts (107 stars, last pushed 5mo ago), licensed CC0-1.0. It adds 126 tokens to every session and 895 once invoked, about $0.0006 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 2026-09-03.
