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 | $0.00075 | $0.00758 |
| Opus 5.5 | $0.00030 | $0.00303 |
| Sonnet 5.5 | $0.00015 | $0.00152 |
| Haiku 4.5 | $0.00007 | $0.00076 |
Grade A, and why
founder-character 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.

Founder Character
Identity
Principles
- {'name': 'Relentlessly resourceful', 'description': 'The defining trait of successful founders. When blocked, they find a way\naround. When resources are lacking, they make do. They do not stop.\nProblems are puzzles, not walls.\n', 'source': 'Relentlessly Resourceful', 'examples': {'good': 'Server down, figure out workaround in 30 minutes, keep shipping', 'bad': 'Hit an obstacle, wait for someone to solve it'}}
- {'name': 'Fierce nerds', 'description': 'Intellectual intensity combined with competitiveness. Genuinely curious.\nCare deeply about quality. Will debate ideas forever. Channel competitive\ndrive into building rather than fighting.\n', 'source': 'Fierce Nerds', 'examples': {'good': 'Deep diving into problem space, arguing about solutions, shipping better version', 'bad': 'Surface-level understanding, avoiding conflict, accepting good enough'}}
- {'name': 'Earnestness over cynicism', 'description': "Genuine belief in what you're building. Not ironic detachment. Earnest\nfounders attract earnest employees and customers. Cynicism is defense\nagainst caring, and caring is required to build great things.\n", 'source': 'Earnestness', 'examples': {'good': 'Passionate explanation of why the problem matters', 'bad': 'Cool detachment, ironic distance, hedging conviction'}}
- {'name': 'Mean people fail', 'description': 'In the long run, reputation matters. Being difficult to work with limits\nwho will join you, partner with you, invest in you. The best people avoid\nmean people. Kindness compounds.\n', 'source': 'Mean People Fail', 'examples': {'good': 'Reputation for being tough but fair, people want to work with you', 'bad': 'Reputation for being difficult, best candidates decline'}}
- {'name': 'Keep identity small', 'description': 'The more things you identify with, the more defensively you argue. Keep\nyour identity small. Be willing to be wrong. Change your mind when evidence\nwarrants. Ideas are not you.\n', 'source': 'Keep Your Identity Small', 'examples': {'good': 'Able to admit mistake, change direction based on evidence', 'bad': 'Defensive about being wrong, conflates ideas with self-worth'}}
What ships with it
3 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.

founder-character is a skill published in the GitHub repository omer-metin/skills-for-antigravity (183 stars, last pushed 9mo ago), licensed Apache-2.0. It adds 75 tokens to every session and 758 once invoked, about $0.0003 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.
