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

dev-code-location 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.

What it actually says

DEV Code Location

When to use

Use before editing code or docs for a DEV task.

Rules

  • Prefer rg and targeted file reads.
  • Read before editing.
  • List candidate files and confidence.
  • Stop if scope or role is unclear.

Required output

Use docs/skills/dev-playbook/code-location.md.

Forbidden actions

  • Do not edit before locating scope.
  • Do not expand into unrelated refactors.
  • Do not overwrite user changes.

Minimal example

Candidate: codeflowmu-shell/src/web-panel.ts
Reason: owns Panel route
Confidence: medium
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.
