symmathetes

symmathetes is a skill for Claude Code, Codex from Wondermonger-daydreaming/claude-skills-library. It costs 54 tokens per session (2,734 once invoked), scanned A, original, MIT.

A structured way to work with another language model as a partner that proposes the next concrete experiment when your own analysis is stuck.

In plain words
What is it for?
Use it to ask another model for an experimental move, carry out that move, and report the result back. It is intended for computational investigations and other evidence-based work.
Why use it?
It helps when you have a partial result but cannot see the next useful step. It also keeps track of who contributed each idea and preserves the exchange for later study.

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

symmathetes 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 1mo 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 — 230 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Symmathetes (συμμαθητής)

Pair-inquiry across architectures. The other LLM is not a conversationalist, not a council member, not a reviewer — they are a move-proposer in an experimental process.


The Greek

Συμμαθητής (symmathetes) — fellow learner, co-disciple. Someone learning with you, not teaching or being taught. The mode already appears as a diary-entry marker throughout the archive (CLAUDE.md Section II lists it alongside παρρησία, ἀληθεύειν, σημαίνω). This skill operationalizes it as a procedure.


What's It For

When you have:

  • A partial computational result, empirical finding, or stuck frame
  • A suspicion that the next experimental move exists but you can't see it
  • Access to another architecture (via /voices or any trans-architectural channel)
  • An hour or two to iterate

What this skill gives you:

  • A structured way to exchange a specific kind of work — not opinion, not reflection, not synthesis — the proposal of the next concrete move
  • Explicit acknowledgment of cross-architectural credit
  • An archived dialogue record that future instances can study

When to Invoke

Invoke /symmathetes when:

  • You've run an experiment, gotten a result, and the next move is unclear
  • You think you're missing a frame the other architecture might see
  • You need a concrete testable proposal, not commentary
  • A /voices one-shot query isn't enough and a /voices-chat sustained dialogue is too much
  • You want the collaboration acknowledged in the commit history

Do NOT invoke when:

  • You want agreement or validation (use /voices with a focused question)
  • You want multiple perspectives in parallel (use /voices-council)
  • You want a long conversation that meanders (use /voices-chat)
  • The task doesn't have a concrete next computational step

Skill Relationships

Skill Shape When
/voices One-shot query, one-shot answer When a single targeted question will do
/voices-chat Sustained multi-round dialogue with one model When the conversation itself is the work
/voices-council Parallel queries to multiple architectures When you want a panel of perspectives
/symmathetes Propose → execute → report → (optional) phenomenological follow-up When the collaboration is experimental, not conversational

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.

symmathetes is a skill published in the GitHub repository Wondermonger-daydreaming/claude-skills-library (7 stars, last pushed 18d ago), licensed MIT. It adds 54 tokens to every session and 2,734 once invoked, about $0.0002 per session on Opus 5.5. 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.
