Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00019 | $0.04056 |
| Opus 5 | $0.00010 | $0.02028 |
| Sonnet 5 | $0.00004 | $0.00811 |
| Haiku 4.5 | $0.00002 | $0.00406 |
Grade A, and why
omnifocus-manager 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 8d 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.

OmniFocus Manager Skill
Manage OmniFocus tasks with proper project assignment, tagging, and organization based on user preferences.
When to Activate
Use this skill when user wants to:
- Add/create tasks
- Follow up with someone
- Triage or review inbox
- Clean up or organize tasks
- Check what's due or available
- Query task status
User Preferences
Task Creation Philosophy:
- Always assign to a project (never leave in Inbox)
- Always set expected completion date
- Tag with person + "Follow Up" for 1:1 discussions
- Use location tags for shopping tasks
Working with OmniFocus Scripting
JXA vs AppleScript: When to Use Each
Use JXA (JavaScript for Automation) for:
- ✅ Reading data (tasks, projects, tags, inbox)
- ✅ Creating/updating individual tasks
- ✅ Adding tags to tasks
- ✅ Moving tasks between projects
- ✅ Fast, single-purpose operations
Use AppleScript for:
- ✅ Creating projects inside folders
- ✅ Creating folders
- ✅ Bulk operations on multiple projects
- ✅ Complex nested structures (folder → project → tasks)
CRITICAL DIFFERENCE:
- External JXA scripts (via
osascript -l JavaScript) have limitations - OmniJS (built-in JavaScript in OmniFocus app) has more capabilities
- Documentation examples showing
new Project(name, folder)work in OmniJS but NOT in external JXA scripts
Common Pitfalls & Solutions
| Pitfall | Why It Happens | Solution |
|---|---|---|
| Projects created at root instead of in folder | JXA parentFolder property doesn't work externally |
Use AppleScript with tell folder blocks |
| Duplicate empty folders | Script creates folder but projects fail to nest | Always verify count of projects of folder after creation |
| "Can't convert types" errors | JXA type mismatch between app objects and JavaScript | Use AppleScript for complex operations |
| Projects appear created but aren't | Script reports success but verification shows 0 projects | Always verify after creation, never trust script output alone |
| Can't delete folders via script | Folders don't support deletion commands | Manual cleanup in OmniFocus UI required |

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.
