keystone-orient

keystone-orient is a skill for Claude Code, Codex from tacoda/keystone. It costs 23 tokens per session (281 once invoked), scanned A, original, MIT.

A planning step for software changes that loads the relevant project state, coding conventions, and process guidance before work begins. It produces a written plan for agreement between the developer and the agent.

In plain words
What is it for?
Use it before a significant code change, after acceptance criteria are written, or when work needs to be re-planned.
Why use it?
It reduces the risk of coding against outdated project information or local conventions. It also helps bring the work back on track when implementation becomes unclear.

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

keystone-orient 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 5d 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

keystone:orient — planning phase

Phase 2 of the six-phase lifecycle. Loads .charter/corpus/state/CODEBASE_STATE.md, the matching idioms for the touched region from corpus/idioms/<stack>/, and the relevant process guides. Output is a written plan the agent and user agree on before implementation starts.

Canonical playbook: .charter/actions/orient.md. Full discipline at .charter/guides/process/planning.md.

Run

Open .charter/actions/orient.md and execute every activity.

When to trigger

  • After /keystone:spec lands acceptance criteria.
  • Before writing any code on a non-trivial change.
  • When the agent loses the plot mid-implementation — re-orient and resync.
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.
