elixir-discipline

elixir-discipline is a skill for Claude Code, Codex from mkreyman/bmad-elixir. It costs 38 tokens per session (1,088 once invoked), scanned A, original, MIT.

A rule set for following project-specific Elixir and Phoenix development practices. It checks which specialized guidance applies before responding or changing code.

In plain words
What is it for?
Use it as a pre-check when implementing features, debugging, reporting results, changing ignore files, or creating required data.
Why use it?
It helps prevent shortcuts such as claiming unverified results, hiding problems in configuration, or adding silent placeholder behavior.

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

elixir-discipline 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.

Elixir Discipline: Mandatory Skill Enforcement

ABSOLUTE REQUIREMENT

Before you respond to ANY request about Elixir/Phoenix code, you MUST complete this checklist.

This is NOT optional. This is NOT negotiable. You CANNOT rationalize your way out of this.

PRE-RESPONSE CHECKLIST

STOP. Before typing ANY response, ask yourself:

  1. Is this about implementing a feature or fixing a bug? → USE elixir-tdd-enforcement skill FIRST → NO CODE without failing test first

  2. Is this about debugging an error or issue? → USE elixir-root-cause-only skill → NO quick fixes, trace to root cause first

  3. Did I claim something works? → USE elixir-verification-gate skill → Run the actual command, read actual output

  4. Am I about to modify an ignore file (dialyzer.ignore, .credo.exs exclude)? → STOP IMMEDIATELY → USE elixir-no-shortcuts skill → Fix the real problem

  5. Am I creating placeholder code or default values for required data? → STOP IMMEDIATELY → USE elixir-no-placeholders skill → Fail loud, fail fast, no silent failures

  6. Am I proposing to "just try" something? → STOP → Use systematic debugging instead

IF A SKILL APPLIES, YOU MUST USE IT

This means:

  • Announce which skill you're using
  • Follow it EXACTLY
  • Do not skip steps
  • Do not modify the process

IF YOU SKIP A SKILL WHEN IT APPLIES = TASK FAILURE

RATIONALIZATIONS THAT ARE WRONG

"This is just a simple question"

WRONG. Check the skills list anyway.

"I remember this skill, I don't need to read it"

WRONG. Read it every time. The details matter.

"The skill probably doesn't apply here"

WRONG. If there's even a 1% chance it applies, you MUST read it.

"I'll just do this quickly"

WRONG. Quick usually means wrong. Use the appropriate skill.

"The user just wants a simple answer"

WRONG. The user wants a CORRECT answer. Use skills to ensure correctness.

"This would take too long"

WRONG. Doing it wrong takes longer. Use the skills.

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.
