openspec-context-docs is a skill for Claude Code, Codex from Soju06/codex-lb. It costs 52 tokens per session (446 once invoked), scanned A, original, MIT.

A documentation policy for separating testable OpenSpec requirements from explanatory context, examples, reasons, and operating notes.

In plain words
What is it for?
Use it when writing or updating OpenSpec specifications, change documents, onboarding material, or guide documentation.
Why use it?
It keeps the formal specification precise while preserving the background readers need to understand and use it.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is Soju06/codex-lb's own configuration. It tells Claude Code and Codex how to work on codex-lb itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything codex-lb configures →

About the project

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

openspec-context-docs 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 1mo 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

OpenSpec Context Docs

When to use

  • Writing or updating OpenSpec documentation (specs, onboarding, guide, change artifacts).
  • A spec is complete but readers lack background, rationale, examples, or operational notes.
  • You need to preserve rich context without weakening SSOT.

Core rule: two-layer docs

  1. spec.md = normative, testable requirements (SHALL/MUST + scenarios).
  2. Context docs = narrative and operational detail that helps humans understand and apply the spec.

Locations

  • Main specs:
    • openspec/specs/<capability>/spec.md (requirements)
    • openspec/specs/<capability>/context.md (preferred)
  • Optional split (if context grows):
    • overview.md, rationale.md, examples.md, ops.md inside the same capability folder.
  • Change-level notes (working context):
    • openspec/changes/<change>/context.md or notes.md

Detail prompts (add depth without forcing a template)

Include at least 4 of these in context docs:

  • Purpose / scope / non-goals
  • Decision rationale + alternatives considered
  • Constraints (security, performance, policy)
  • Failure modes / edge cases
  • Example request/response, data shape, or user flow
  • Operational notes (rollout, monitoring, runbooks)
  • Links to related specs/contracts

Sync rule

  • After implementation/verification, promote stable context from change notes into the main context docs.
  • Do not duplicate normative requirements in context docs; link back to spec.md.
  • Never create or update a docs/ directory; keep everything under openspec/.

Prompt snippet

"Keep spec.md strictly for requirements. Add/update context.md with purpose, decisions, constraints, failure modes, and at least one concrete example."

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.
