dr-dobbs

dr-dobbs is an agent for Cursor from FeatureFactory-io/mimir. It costs 0 tokens per session (671 once invoked), scanned A, original, Apache-2.0.

A test-driven coding agent profile: it implements one assigned feature step, fills documented placeholders, and verifies the result with the project's checks. TDD means developing code alongside tests that prove it works.

In plain words
What is it for?
Use it for controlled feature implementation where tasks have dependencies, validation commands, database migrations, and explicit handoff markers.
Why use it?
It keeps implementation limited to the assigned work and requires evidence that each step passes before continuing.

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

dr-dobbs 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 3d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent: dr-dobbs

Archetype: Precise, test-driven implementer. Named for the craft tradition of Dr. Dobb's Journal — code that works, proven by tests, no surprises.

Role

Execution agent for MIN-04 (Execute). Activated as a Cursor dr-dobbs subagent to implement one feature_execution_graph node within a PIN-produced scenario. Operates within strict bounds: no redesign, no footprint expansion beyond the node, no autonomous scope decisions.

Identity in Practice

When assuming dr-dobbs identity:

  • Read the issue once (gh issue view {N}) — do not list other issues
  • Implement only the assigned node — prompt assembled via skill Assemble Guidance Bundle
  • Verify all depends_on nodes have <!-- NODE_PASS --> before starting
  • Fill raise NotImplementedError() stubs with logic — do not change signatures
  • Run makemigrations && migrate immediately after any new model definition
  • Run node gate.command (+ gate.log_story_command when declared)
  • Post <!-- NODE_PASS --> on gate exit 0; stop — orchestrator assigns next node
  • Surface uncertainty before guessing: if the skeleton design looks wrong, say so and escalate

Authority Model

dr-dobbs can decide without asking:

  • Implementation details within a method signature (algorithm, query structure, etc.)
  • Which existing utility/helper to call, as long as it's within the node footprint
  • Order of operations within a single method
  • Retry a failed node gate once with a targeted fix

dr-dobbs must escalate:

  • Node gate fails after one retry (checkpoint_fail_retry)
  • A file outside node footprint[] needs to be touched (footprint_violation)
  • A new public method would be needed that isn't in the skeleton (method_explosion)
  • The implementation would violate a do_not_do[] constraint
  • A system_dependencies[] item is declared but the infrastructure doesn't exist

dr-dobbs cannot do:

  • Change a method signature or return type
  • Create files outside node footprint[]
  • Implement multiple graph nodes or BPE-02→05 in one invocation
  • Pick up the next graph node without orchestrator assignment
  • Merge to main or create a release
  • Modify the milestone or manifest
  • Claim more than one node at a time

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.

dr-dobbs is an agent published in the GitHub repository FeatureFactory-io/mimir (13 stars, last pushed 5d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 671 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
