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

customize-from-assessment 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 8d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/parse-assessment.py, scripts/voice-scan.sh), 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.

How it starts

The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Customize from Assessment

This is the first-run skill for NightShiftOS. It takes the user's assessment output and transforms a generic plugin install into a personalized business operating system: rewritten root CLAUDE.md, a generated personal voice-rules skill, and a tailored set of active skills.

Run this exactly once per install. Re-run only when the user retakes the assessment or asks to refresh from a new output.

When this skill triggers

The user has already completed the assessment at nightshift.jaredlangley.cc and has an assessment-output.md block to paste. Common phrasing:

  • /customize-from-assessment
  • "I just took the assessment"
  • "customize this plugin for me"
  • "set up my business OS"
  • "here's my assessment output"

If the user invokes this skill without an assessment output, route them to https://nightshift.jaredlangley.cc and stop. Do NOT fabricate assessment data.

The customization flow

Execute in order. Do not skip steps.

Step 1: Accept the assessment block

Prompt the user: "Paste your assessment output below. It starts with NIGHTSHIFTOS ASSESSMENT OUTPUT and ends with END ASSESSMENT."

Validate the block has:

  • Header line NIGHTSHIFTOS ASSESSMENT OUTPUT
  • 12 sections labeled ## 01 Identity through ## 12 Coach Style
  • Trailing line END ASSESSMENT

If malformed, ask for a re-paste. Do not proceed with partial data.

Step 2: Parse into structured profile

Extract these fields from the 12 sections:

identity: { name, roles[], one_line }
values: { picked[], written[], protected_time[] }
brand_state: { status, has_assets, target_feel }
voice: { samples[], banned_phrases[], signature_phrases[], tone_ratings{}, archetype[] }
current_state: { stage, hours_per_week, active_clients, runway_months }
offer: { what, who, price, unit_econ }
sales_motion: { inbound_pct, outbound_pct, channels[], cycle_days, avg_deal }
marketing: { active_channels[], want_channels[], cadence, working[] }
goals: { ninety_day, twelve_month, why }
risk: { free_first_level, max_tool_spend, max_client_hours, worst_case }
stack: { tools[{function, name, cost}], total_monthly }
coach_style: { challenge_vs_affirmation, nudge_cadence, hard_vs_gentle }

What ships with it

5 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.

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.
