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.

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 | $0.00016 | $0.01015 |
| Opus 5 | $0.00008 | $0.00508 |
| Sonnet 5 | $0.00003 | $0.00203 |
| Haiku 4.5 | $0.00002 | $0.00102 |
Grade A, and why
source-command-opsx-sync 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.
This is a copy
75% identical to openspec-sync-specs — 37 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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.
source-command-opsx-sync
Use this skill when the user asks to run the migrated source command opsx-sync.
Command Template
Sync delta specs from a change to main specs.
This is an agent-driven operation - you will read delta specs and directly edit main specs to apply the changes. This allows intelligent merging (e.g., adding a scenario without copying the entire requirement).
Input: Optionally specify a change name after /opsx:sync (e.g., /opsx:sync add-auth). If omitted, check if it can be inferred from conversation context. If vague or ambiguous you MUST prompt for available changes.
Steps
-
If no change name provided, prompt for selection
Run
openspec list --jsonto get available changes. Use the AskUserQuestion tool to let the user select.Show changes that have delta specs (under
specs/directory).IMPORTANT: Do NOT guess or auto-select a change. Always let the user choose.
-
Find delta specs
Look for delta spec files in
openspec/changes/<name>/specs/*/spec.md.Each delta spec file contains sections like:
## ADDED Requirements- New requirements to add## MODIFIED Requirements- Changes to existing requirements## REMOVED Requirements- Requirements to remove## RENAMED Requirements- Requirements to rename (FROM:/TO: format)
If no delta specs found, inform user and stop.
-
For each delta spec, apply changes to main specs
For each capability with a delta spec at
openspec/changes/<name>/specs/<capability>/spec.md:a. Read the delta spec to understand the intended changes
b. Read the main spec at
openspec/specs/<capability>/spec.md(may not exist yet)c. Apply changes intelligently:
ADDED Requirements:
- If requirement doesn't exist in main spec → add it
- If requirement already exists → update it to match (treat as implicit MODIFIED)
MODIFIED Requirements:
- Find the requirement in main spec
- Apply the changes - this can be:
- Adding new scenarios (don't need to copy existing ones)
- Modifying existing scenarios
- Changing the requirement description
- Preserve scenarios/content not mentioned in the delta
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.

source-command-opsx-sync is a skill published in the GitHub repository killin0415/memoir (5 stars, last pushed 2mo ago), licensed MIT. It adds 16 tokens to every session and 1,015 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 75% identical to openspec-sync-specs, differing in 37 lines, and is treated as a copy.
