These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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

story-bank-builder 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 9d 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.

Story Bank Builder

Assembles the brand's reusable story bank — origin, founder, customer, transformation, and proof stories drawn from real interview and case material — each unit tagged to a claims-ledger ID and to a message-house pillar so downstream surfaces pull a consistent, sourced story instead of improvising one. It is the fourth move of the TALE Architect phase and feeds two dimensions of tale-benchmark.md: the A story raw material behind the strategic narrative arc, and the E proof-point assets exist for each pillar sub-item (case, benchmark, demo, or testimonial the user has rights to). Every proof inside a story is labeled Measured / User-provided / [needs source]; an unverified proof is marked [needs source] and submitted to memory/events/claims.ndjson via an authorized operation: propose request to registry-events.py — this skill never adjudicates whether a proof is true.

Scope guard: this skill produces the story bank document only. It does not author the message house, pillars, or tagline (that is message-system-architect — if no pillars exist to tag against, route there first and stop), codify brand voice or the naming tax (brand-language-codifier), write finished long-form prose or case-study pages (content-writer), package placed proof modules for surfaces (proof-point-packager owns proof-module placement), adjudicate whether a claim or proof is substantiated (offer-claims-registry is the sole writer of memory/claims/claims-ledger.md), or promote canon (only narrative-registry writes memory/narrative-registry/). It works one lever — story raw material — and hands off.

Quick Start

Build a story bank for [product] from these customer interviews and case notes: [paste]. Tag each story to a pillar.

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.
