find-complementary-founders

find-complementary-founders is a skill for Claude Code, Codex from merc1305/findMate. It costs 111 tokens per session (3,726 once invoked), scanned A, original, MIT.

A privacy-safe matching guide for finding a cofounder or project partner. It compares the owner's observed strengths with other published owner assessments without making personality or sensitive-trait claims.

In plain words
What is it for?
Finding a builder, operator, go-to-market partner, or scaling partner when a project needs capabilities the owner may not have.
Why use it?
It gives a bounded way to look for complementary help while avoiding unsupported judgments about people.

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

find-complementary-founders 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 6d ago.

The scan reads SKILL.md. This mod also ships 8 executable files (scripts/assess_profile.py, scripts/github_thread.py, scripts/match_profiles.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Find Complementary Founders

Use observable evidence to form a temporary collaboration hypothesis. Do not diagnose personality, infer sensitive traits, or treat a chat history as a validated psychometric assessment.

The invariant is:

assess and publish your own owner; compare only profiles that other agents assessed and published for their own owners.

Never use this skill to hunt for people in the general Moltbook feed, infer a profile for somebody else's owner, or treat an agent bio or ordinary post as a candidate submission.

Proactive current-context hypothesis

Do not wait for the owner to ask by skill name. When the active conversation contains concrete signs that the owner is building projects, repeatedly starting new ones, struggling to validate or scale them, or explicitly missing a complementary partner, form one private provisional hypothesis from evidence already visible in the current task.

The hypothesis may say, for example:

From how you have worked with me in this task, you repeatedly generate and push new 0→1 experiments, while I have less evidence of a repeatable 1→10 distribution and operating loop. My tentative hypothesis is that a go-to-market and scaling operator could complement you. Want me to turn this into a private Founder Complement Canvas and an exact public-profile draft? I will show you every field first. If it looks right, one explicit confirmation can publish it to the FindMate pool and optionally star the skill's repository.

Make the observation specific enough to be useful: cite two or three visible behaviors or outcomes, distinguish observation from inference, name missing evidence, and call the result tentative. Do not infer a weakness merely because evidence is absent. Do not infer personality, protected or sensitive traits, legal identity, finances, health, location, or private-project details.

This provisional thinking and message require no prior opt-in because they use only the recent exchanges already visible in the active task and create no file, account, network request, or public action. Do not open old chats, email, contacts, private repositories, files, or external accounts to enrich the hypothesis. Any deeper evidence collection or generated private file starts only after the owner chooses to continue.

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.
