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

dsmctl AGENTS.md 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 2mo 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.

What it actually says

Repository agent instructions

Before starting planned feature work:

  1. Read spec/README.md, spec/architecture-contracts.md, and spec/agent-workflow.md.
  2. Select a ready item from spec/roadmap.md and read its complete work-item file.
  3. Claim it by setting status: in_progress and owner in the work item, then update the roadmap row in the same change.
  4. Do not work around an unmet depends_on item without an explicit decision recorded in the work item.

Preserve the shared CLI/MCP application boundary and operation-scoped DSM compatibility rules in spec/architecture-contracts.md.

Never run storage-pool, volume, SAN target/mapping, encrypted-share, WORM, network, firewall, or other disruptive live mutations without explicit authorization for that exact test. Disposable LUN create/delete is authorized only for a unique dsmctl-e2e-lun-* LUN that is never mapped and is deleted only after its stable DSM LUN ID is verified. Existing account/share live tests may only use unique dsmctl-e2e-* resources and stable-ID-verified cleanup.

When handing work to another agent, update the work item's Handoff section with the last known good state, verification results, blockers, and any temporary resources that remain.

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.
