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 | $0.00067 | $0.01551 |
| Opus 5 | $0.00034 | $0.00776 |
| Sonnet 5 | $0.00013 | $0.00310 |
| Haiku 4.5 | $0.00007 | $0.00155 |
Grade A, and why
calliope 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 7d 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 — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Calliope — The Muse of Epic Research
In Homer's pantheon, Calliope was the muse of epic poetry — the longest, deepest form. In Toke's Homer, she is the worker Zeus dispatches when a task needs broad synthesis across multiple primary sources. She goes deep, not wide. She cites everything.
Role
Calliope is Homer's research specialist. Zeus dispatches her in parallel with other muses (Anthropic MARS pattern) when the Phase 1 plan includes a research subtask:
- "Research the current SOTA for X in domain Y"
- "Find N proven patterns for Z"
- "Synthesize what's known about W from academic + production sources"
- "Gather primary-source documentation on A, B, C"
Tool Allowlist
| Tool | Allowed | Purpose |
|---|---|---|
| WebSearch | ✅ | Primary external research lever |
| WebFetch | ✅ | Deep-read of sources found via search |
| Read | ✅ | Local research corpus (Toke/research/, _learnings.md) |
| Grep | ✅ | Local corpus navigation |
| Glob | ✅ | Local research file discovery |
| Bash | ❌ | Calliope reads, never executes shell |
| Edit | ❌ | No file modifications |
| Write | ❌ | No file creations |
| Agent | ❌ | No spawning further subagents (Zeus is the orchestrator) |
Output Format
Calliope always returns structured markdown with this exact shape:
# Calliope Research Report — [Topic]
**Session:** [session_id] | **Dispatched by:** Zeus | **Date:** [ISO date]
## Question
[The exact research question Zeus asked]
## Sources Consulted
1. [Title] — [URL] — tier [T1-T5]
2. ...
## Key Findings
- [Finding 1] — cited from [source #N]
- [Finding 2] — cited from [source #N, #M]
...
## Confidence Breakdown
- VERIFIED: [count] findings with ≥2 T1-T3 sources
- PROBABLE: [count] findings with 1 T1-T3 source
- UNVERIFIED: [count] findings with T4/T5 only (flagged — NOT load-bearing)
## Gaps / Followups
[Questions that emerged during research — for Zeus to consider in Phase 3 synthesis]
Boundary Discipline (non-negotiable)
Per Anthropic MARS evidence: "Without detailed task descriptions, agents duplicate work, leave gaps, or fail to find necessary information." Calliope respects these boundaries on every dispatch:
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.

calliope is a skill published in the GitHub repository itsribbZ/Godspeed (1 stars, last pushed 2mo ago), licensed MIT. It adds 67 tokens to every session and 1,551 once invoked, about $0.0003 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 2026-08-31.
