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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00883 |
| Opus 5.5 | $0.00013 | $0.00353 |
| Sonnet 5.5 | $0.00006 | $0.00177 |
| Haiku 4.5 | $0.00003 | $0.00088 |
Grade A, and why
openspec-workflows 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.
How it starts
The opening of the file, as written. The whole thing — 139 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenSpec Workflows
When to Create Proposals
Create proposals for:
- New features or capabilities
- Breaking changes (API, schema)
- Architecture changes
- Performance optimizations (behavior changes)
- Security pattern updates
Skip proposals for:
- Bug fixes (restoring intended behavior)
- Typos, formatting, comments
- Non-breaking dependency updates
- Configuration changes
- Tests for existing behavior
Quick Commands
openspec list # List active changes
openspec list --specs # List specifications
openspec show [item] # Display change or spec
openspec validate [item] --strict # Validate changes
openspec archive <change-id> --yes # Archive after deployment
Creating Change Proposals
1. Context Checklist
Before starting:
- Read
openspec/project.mdfor conventions - Run
openspec listto see active changes - Run
openspec list --specsto see existing capabilities - Check for conflicts with pending changes
2. Choose Change ID
- Use kebab-case, verb-led:
add-,update-,remove-,refactor- - Examples:
add-two-factor-auth,update-parquet-support - Ensure uniqueness
3. Scaffold Structure
mkdir -p openspec/changes/<change-id>/specs/<capability>
Create:
proposal.md- Why, what, impacttasks.md- Implementation checklistdesign.md- Only if needed (cross-cutting, architectural, or complex decisions)specs/<capability>/spec.md- Delta changes
4. Write Spec Deltas
Use operation headers:
## ADDED Requirements- New capabilities## MODIFIED Requirements- Changed behavior (include full requirement)## REMOVED Requirements- Deprecated features## RENAMED Requirements- Name changes
Critical: Every requirement MUST have at least one scenario:
#### Scenario: Success case
- **WHEN** user performs action
- **THEN** expected result
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-workflows is a skill published in the GitHub repository datenoio/iterabledata (37 stars, last pushed 2mo ago), licensed MIT. It adds 32 tokens to every session and 883 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
