strata:procedure

strata:procedure is a skill for Claude Code, Codex from gideondk/strata. It costs 120 tokens per session (652 once invoked), scanned A, original, MPL-2.0.

A guide for recording repeatable procedures such as recipes, checklists, release instructions, and debugging steps. It stores how a team carries out a task.

In plain words
What is it for?
Use it to document onboarding, releases, migrations, testing routines, or common fixes, with prerequisites and a verification step.
Why use it?
It keeps useful workflows from being forgotten and helps future engineers repeat them consistently.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

strata:procedure 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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

strata:procedure

The "how" notes. Distinct from domain (the "what") and decisions (the "why"). A procedure tells a future engineer (or future Claude) the sequence of Steps to reproduce something.

What goes here

  • Onboarding checklists: "first day on this codebase"
  • Service templates: "how to add a new bounded context"
  • Release runbooks: "shipping a hotfix"
  • Test patterns: "writing a new aggregate test"
  • Migration recipes: "moving a service to the new pattern"
  • Common debugging flows: "what to check when X breaks"

What does NOT belong:

  • One-off scripts → keep in code
  • Decisions WHY you do it this way → /strata:decide
  • What a thing IS → /strata:domain
  • "What happened on this branch" → /strata:save

How

User runs /strata:procedure <title> or you autonomously identify a Workflow worth capturing. You:

  1. Compose the procedure as a numbered step list with prerequisites + a verification step.
  2. Recall first. Call recall(query="<title>", scope="procedural", layer=1). If a near-duplicate already exists (e.g. "shipping a hotfix" vs "hotfix release runbook"), extend that one instead of adding a second.
  3. Invoke:
cat <<'EOF' | "${CLAUDE_PLUGIN_ROOT}/bin/strata" procedure \
    --title "<title>"
# <Title>

## Prerequisites
- ...

## Steps
1. ...
2. ...

## Verify
- ...

## When to use this procedure
<one sentence>
EOF

Lands in <vault>/<repo>/procedural/<slug>.md.

Shape

Always: title, prerequisites, numbered steps, verification, applicability. The verification step is what makes it executable, without it, the Procedure is just narrative.

If a step references code, use backticks (OrderAggregate.cs), those get Verified against the code graph in /strata:review.

Don't do

  • Don't write a procedure for something that happens once. Procedures are for the recurring shape.
  • Don't dump command transcripts. Synthesise into "do A, then B, then verify C."
  • Don't write a procedure when a decision is what's needed. "We use Postgres" is a decision; "how to add a new Postgres-backed table" is a procedure.

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.

strata:procedure is a skill published in the GitHub repository gideondk/strata (5 stars, last pushed 1mo ago), licensed MPL-2.0. It adds 120 tokens to every session and 652 once invoked, about $0.0006 per session on Opus 5. 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 2026-08-31.
