openspec-quickstart

A short guide for proposing schema changes, breaking exported interfaces, and major architecture changes in OpenSpec. OpenSpec is a project process that records planned changes as proposals, tasks, designs, and requirements.

In plain words
What is it for?
Use it before changing data schemas, public exports, or architecture, and to validate the resulting OpenSpec proposal.
Why use it?
It helps teams agree on changes before implementation and ensures requirements include testable scenarios. It also distinguishes changes that need proposals from ordinary bug fixes and non-breaking updates.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-quickstart 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 2d 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.

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

OpenSpec quickstart for agents

Short guide for schema changes and breaking exports. Full reference: openspec/AGENTS.md.

When to create a proposal

Do propose for: new capabilities, breaking schema/export changes, architecture shifts.

Skip proposal for: bug fixes restoring spec behavior, typos, non-breaking dependency updates, tests for existing behavior.

Checklist

  1. Run openspec list and openspec list --specs — check for conflicts.
  2. Pick a unique verb-led change-id (e.g. add-field-catalog, update-borders-policy).
  3. Scaffold under openspec/changes/<change-id>/:
    • proposal.md — why, what, impact
    • tasks.md — implementation checklist
    • design.md — only if cross-cutting or ambiguous
    • specs/<capability>/spec.md — deltas with ## ADDED|MODIFIED|REMOVED Requirements
  4. Every requirement needs at least one #### Scenario: block.
  5. Run openspec validate <change-id> --strict and fix all issues.
  6. Do not implement until the proposal is approved.

Scenario format (required)

#### Scenario: Descriptive name
- **WHEN** condition
- **THEN** expected outcome

Use #### Scenario: (four hashes). Bullets or ### Scenario: will fail validation.

MODIFIED requirements pitfall

When modifying an existing requirement, copy the full requirement block from openspec/specs/<capability>/spec.md into the delta and edit it. Partial MODIFIED deltas drop detail at archive time.

Dataset scope

Countries are reference data only. Do not propose socioeconomic profile fields (HDI, GDP, government type, internet penetration).

CLI essentials

openspec list                  # active changes
openspec list --specs          # capabilities
openspec show <id> --json --deltas-only
openspec validate <change-id> --strict
openspec archive <change-id> --yes   # after deployment

Workflows

  • .agent/workflows/openspec-proposal.md — scaffold a change
  • .agent/workflows/openspec-apply.md — implement an approved change
  • .agent/workflows/openspec-archive.md — archive after deployment

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.

openspec-quickstart is an agent published in the GitHub repository datenoio/internacia-db (11 stars, last pushed 13d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 518 tokens. 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 2026-08-30.
