no-surrender

A guided check of how well a user understands a claim, including its mechanism, consequences, ways it could be disproved, and limits. It records the result in the claim's engagement data when explicitly enabled.

In plain words
What is it for?
Use it to test understanding of a knowledge-base claim and record which parts of the reasoning have been considered.
Why use it?
It helps distinguish ideas the user has genuinely examined from ideas they have merely accepted. The setting prevents the check from running unless deliberate approval is configured.

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

no-surrender 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 2d 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 — 240 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/no-surrender

Intent. Test the user's mental grip on a claim. Write the result to the claim's engagement vector so the vault knows what the user has actually engaged with vs. what they've absorbed without verification. Read surrender-tracking-design.md at the repo root for the design rationale.

This verb is the architectural circuit-break for the calibration loop (model emits high confidence without reasoning; user accepts without verification). It is the only verb in the vault that writes engagement.

Gating — read every invocation, never cache

Step 1, always. Read vault/vault.yaml. Check surrender.enabled.

  • If surrender.enabled is missing, false, or anything other than literal true: print this and exit immediately:
    /no-surrender is gated by surrender.enabled in vault.yaml. Set surrender.enabled: true to enable.
    
  • Do not proceed. Do not write any file. Do not read any claim. The gate is the first action and the first thing to fail.

This is a behavioural gate (skill-instruction layer), not a runtime gate. The flag exists to make activation deliberate. Re-read on every invocation — never assume it's still on from a prior call.

Target forms

Single argument forms (mutually exclusive):

Form Example Behaviour
[[wikilink]] /no-surrender [[ai-tutor-design-must-embed...]] Resolve wikilink to file in notes/claims/ or notes/synthesis/; test that one claim
Path /no-surrender notes/claims/some-claim.md Test that one claim
_<topic-map> /no-surrender _ai-in-education Read MOC; sequentially test each claim under ## Core claims. User can /stop between claims.
--weakest=N /no-surrender --weakest=5 Find N claims with lowest current effective engagement (after decay); test in order
--recent-since=Nd /no-surrender --recent-since=14d Test claims with created date within last N days

Optional modifier:

  • --axis=<name> — force a specific axis (mechanism, implications, falsifiability, bounds). Overrides default axis selection.

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.

Changes

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.

no-surrender is a skill published in the GitHub repository letrplB/second-brain (1 stars, last pushed 3mo ago), licensed MIT. It adds 47 tokens to every session and 2,995 once invoked, about $0.0002 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.
