A session-start routine that loads workspace information, checks business systems, and summarizes current priorities. It also recommends relevant skills for the day.

Use it at the start of a working session to review personal and business context, pipeline work, current data, and available next actions.

It reduces the time spent gathering context and helps begin work with an accurate view of priorities and system health.

SkillSpector: 1 finding, up to medium

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 →

medium Excessive Agency · line 7
Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.

Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.03417
Opus 5	$0.00039	$0.01708
Sonnet 5	$0.00016	$0.00683
Haiku 4.5	$0.00008	$0.00342

Security

Grade A, and why

prime 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 4d 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 — 217 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Prime

Initialize the session. Load full context. Surface priorities. Recommend today's agents.

Read

First, read .workspace-identity.json to determine workspace type.

CLAUDE.md is already auto-loaded by the Claude Code harness (visible in the system prompt's claudeMd block) - do NOT re-read it.

Load the following files in this order (paths depend on workspace type):

CEO workspace (flat paths):

context/personal-info.md - who Misha is
context/business-info.md - 31C organization and ODUN.ONE
context/strategy.md - strategic priorities and arc
context/current-data.md - current metrics, milestones, active workstreams
context/people.md - read only the "Top 10 Active Contacts (summary)" section. Full file remains available - Read context/people.md when a specific named contact requires deeper context.
context/pipeline.md - active deals and investor conversations
reference/workspace-overview.md - read only the H1 + "## Index" section. Defer the per-section detail to lazy-read when a specific tool, script, or system needs deeper context.
datastore/INDEX.md - read only the H1 + "## Top-Level Structure (summary)" section. Defer the per-document tables to lazy-read when a specific fact needs validating.

Exec workspace (shared content under corporate/, personal under personal/):

personal/context/personal-info.md - who the exec is
corporate/context/business-info.md - 31C organization and ODUN.ONE
corporate/context/strategy.md - strategic priorities and arc
corporate/context/current-data.md - current metrics, milestones, active workstreams
corporate/context/people.md - read only the "Top 10 Active Contacts (summary)" section when present. Full file remains available for lazy-read.
corporate/context/pipeline.md - active deals and investor conversations
corporate/datastore/INDEX.md - read only the H1 + "## Top-Level Structure (summary)" section when present.

What ships with it

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.
