session-start

session-start is a skill for Claude Code, Codex from slowdoctor-dev/workspace-md. It costs 64 tokens per session (1,200 once invoked), scanned A, original, Apache-2.0.

A session-opening workflow that loads the workspace’s instruction order, checks whether the runtime has changed, consumes the next-task buffer, and briefs the owner. It is intended for later sessions, not first-time setup.

In plain words
What is it for?
Use it at the start of a session to load required guidance, check runtime details, process NEXT.md, and confirm the working direction.
Why use it?
It helps the assistant begin with the right project context and notice configuration drift before working.

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

session-start 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 1mo 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.

When to use

At the beginning of every working session. Not the first-time bootstrap (use init for that).

Requires

Requires 3-control/foundation/SOUL.md, 3-control/foundation/PRINCIPLE.md, and 2-mind/garden/essential/ to exist. If any are missing, run init instead of continuing.

Quick reference

Step Reads Writes
1. Quick integrity + runtime drift check repo structure + 3-control/runtime/profile.md + detect-runtime result —
2. Load read order 7 files (see Procedure §2) —
3. Consume NEXT garden/essential/NEXT.md clears NEXT.md content
4. Brief Owner (compiled from loaded files) —
5. Confirm direction (Owner reply) —

Procedure

1. Lightweight integrity check + runtime drift detection

Confirm 4 top folders + 2-mind/garden/ + 2-mind/forge/ + 3-control/foundation/{SOUL,PRINCIPLE}.md are present. If broken, escalate to init.

Invoke detect-runtime skill in drift-check mode (cheap re-detect using cached self-introspection where possible). Compare against active 3-control/runtime/profile.md:

  • profile.md present + detection matches → silent pass; use profile.md's active_tier
  • profile.md present + harness, backend_model, or effective_context differs → surface diff to Owner + propose re-ratify; default behavior = continue with profile.md's tier for this session
  • profile.md absent → default active_tier = standard (R1 baseline) for this session; remind Owner to run /init to create active profile.md from 3-control/runtime/profile.example.md
  • detect-runtime fails or returns uncertain (no shell access, headless, network unreachable) → continue silently with profile.md's tier (or standard if absent); record the failure in the audit-log next time audit runs

2. Load read order (7 items, in sequence)

Canonical: 3-control/foundation/use-driven-memory.md §Read order. Keep this operational list numerically in sync with that source.

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.
