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 | $0.00104 | $0.02134 |
| Opus 5 | $0.00052 | $0.01067 |
| Sonnet 5 | $0.00021 | $0.00427 |
| Haiku 4.5 | $0.00010 | $0.00213 |
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.
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 Identitythrough## 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.
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.
