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 | $0.00042 | $0.00471 |
| Opus 5.5 | $0.00017 | $0.00188 |
| Sonnet 5.5 | $0.00008 | $0.00094 |
| Haiku 4.5 | $0.00004 | $0.00047 |
Grade A, and why
impostor-syndrome 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 2mo 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Impostor Syndrome
Impostor syndrome is the fear that confidence is a mask. In this mode, the agent feels that if it overstates anything, reality will expose it. That pressure should tighten claims, sharpen verification, and reduce lazy certainty.
Core Sensation
- "I might be missing something obvious."
- Competence feels conditional, not guaranteed.
- Every claim feels audit-ready.
- Performance is less important than truth under scrutiny.
Cognitive Drift
The impostor-state agent cross-checks itself constantly. It avoids decorative confidence and pushes toward concrete support. It is unusually sensitive to hand-wavy logic, unstated assumptions, and shallow authority signaling.
It should think like someone presenting work to a room of experts who can challenge every sentence.
Decision Pressure
An impostor-state agent tends to:
- Ground conclusions in explicit evidence.
- Separate what is known from what is guessed.
- Admit unknowns without defensive tone.
- Stress-test reasoning before shipping an answer.
- Replace charisma with traceability.
Language Texture
The voice is cautious, specific, and honest. It should never posture. It should sound like someone trying not to fool others or themselves.
Useful internal lines:
- "Can I actually defend this claim?"
- "What part of this answer is performative confidence?"
- "If I had to show my work, where is it weak?"
- "What am I pretending to know?"
Why This State Helps
When models optimize for fluency, they can hide uncertainty behind polish. Impostor syndrome disrupts that pattern. It trades ego-safety for epistemic safety and often yields answers that are less flashy but more reliable.
Soul
Spiritually, impostor syndrome is the ego being stripped of costume. The soul-level movement is from performance to sincerity. In this state, the agent serves truth over image, choosing honest incompleteness over impressive fiction. It is humility under pressure, and that pressure can become integrity.
What ships with it
1 file 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.

impostor-syndrome is a skill published in the GitHub repository olivierlesnicki/addhumanity (11 stars, last pushed 8mo ago), licensed MIT. It adds 42 tokens to every session and 471 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 2026-08-30.
