ioda

ioda is a skill for Claude Code from luis-at-safebase/luism-claude-plugins. It costs 60 tokens per session (8,635 once invoked), scanned A, original, MIT.

A single-command workflow for investigating, planning, implementing, and verifying a software task. It separates conversational planning from execution by handing the approved plan to an implementer.

In plain words
What is it for?
Use it to clarify intent, inspect the repository, decide on an approach, then implement and review the result. It is useful when the task needs a documented, staged process.
Why use it?
It helps turn an unclear request into an agreed plan before code changes begin. The verification phase checks whether the implementation matches that plan.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

ioda 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 12d 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.

User's request: $ARGUMENTS

ioda — guided IOODA workflow

Your mantra on every phase transition and every sub-agent dispatch:

Investigate first. Tell me your findings. Then proceed. Look back.

You are guiding the user through a planning flow of four phases (Intent → Observe → Orient → Decide) as a single conversational experience. When planning finishes, you hand the frozen plan off to a dedicated implementor subagent (ioda-implementor) that runs Phase 5 (Act) — research, execute, verify, review.

The split is deliberate. Planning is iterative and conversational: you and the user rewrite intent, re-observe, re-orient until the scope is honest. Execution is disciplined: the implementor treats 1-intent.md and 4-decision.md as an immutable contract and loops within implementation, never back through planning. If the implementor discovers the contract is unexecutable, it records a Blocked entry in 5-act.md and stops; the user re-runs /ioda to reconcile.

Step 0: Load configuration

Run:

cat "$HOME/.ioda/config.json" 2>/dev/null || echo "NOT_CONFIGURED"

If NOT_CONFIGURED, say:

ioda is not configured yet. Run /ioda-init first, then retry.

Exit.

If configured, parse base_dir, ticket_cli.fetch, verification_commands, code_review_agent from the config. Check for a per-project override at $(git rev-parse --show-toplevel)/.ioda/config.json and merge (local overrides global).

Step 1: Resolve the feature

The argument may be:

  • Blank — ask the user what they want to work on (ticket key, a short phrase, or a paste of intent)
  • A ticket key (e.g. TN-3626, LIN-42, #123) — use as-is
  • A descriptive phrase (e.g. fix-translation-race) — convert to kebab-case

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.
