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 | $0.00012 | $0.00443 |
| Opus 5 | $0.00006 | $0.00221 |
| Sonnet 5 | $0.00002 | $0.00089 |
| Haiku 4.5 | $0.00001 | $0.00044 |
Grade A, and why
create-session 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 yesterday.
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
Create Session
Create a date-based session folder for today's work artifacts.
Arguments
$ARGUMENTS - Optional topic description for the session
Step 1: Generate Session Name
Format: YYYY-MM-DD_topic-description
If no topic provided, use: YYYY-MM-DD_work-session
Examples:
2025-01-15_api-research2025-01-15_client-meeting-prep2025-01-15_work-session
Step 2: Check for Existing Session
Look for existing session folder for today:
ls -d sessions/$(date +%Y-%m-%d)_* 2>/dev/null
If exists:
- Show existing session(s)
- Ask if user wants to use existing or create new
Step 3: Create Session Folder
mkdir -p "sessions/YYYY-MM-DD_topic/"
Step 4: Create Session README
Write sessions/YYYY-MM-DD_topic/README.md:
# Session: [Date] - [Topic]
## Focus
[What this session is about]
## Work Items
- [ ] Item 1
- [ ] Item 2
## Files
| File | Purpose |
|------|---------|
| (none yet) | - |
## Outcomes
(To be filled at session end)
## Move to Projects
Files to move to permanent project locations:
- [ ] file.ext → projects/project-name/
Step 5: Update Session Index
Append to sessions/SESSION_INDEX.md:
| [Date] | [Topic] | - | - |
Step 6: Report
Tell user:
- Session folder created at
sessions/[folder]/ - Use for temporary work, research, drafts
- Move final outputs to
projects/when done - Delete temp files when no longer needed
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.

create-session is a skill published in the GitHub repository Abilityai/abilities (11 stars, last pushed 14d ago), licensed MIT. It adds 12 tokens to every session and 443 once invoked, about $0.0001 per session on Opus 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.
