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.

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 | $0.00717 |
| Opus 5 | $0.00016 | $0.00358 |
| Sonnet 5 | $0.00006 | $0.00143 |
| Haiku 4.5 | $0.00003 | $0.00072 |
Grade A, and why
session-handoff 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 9d 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 — 105 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Session Handoff
Generates a detailed handoff document capturing the current state of work, enabling seamless continuation in a fresh AI session.
When to Use This Skill
- Ending a long coding session that will continue later
- Switching between AI tools or models mid-task
- Context window approaching limits, need a fresh session
- Handing off work to a teammate (human or AI)
What This Skill Does
Generate a structured handoff document with:
1. Current State Summary
## Session Summary
**Task**: [What was being worked on]
**Branch**: [Current git branch]
**Status**: [In progress / Blocked / Ready for review]
**Started**: [When work began]
2. What Was Done
## Completed Work
1. [Task 1] — [files changed, what was done]
2. [Task 2] — [files changed, what was done]
### Key Decisions Made
- Chose X over Y because [reason]
- Used pattern Z from [existing file] for consistency
3. What Remains
## Remaining Work
1. [ ] [Next task] — [specific files, what to do]
2. [ ] [Following task] — [dependencies, approach]
### Blockers
- [Any blocking issues with context]
4. Relevant Context
## Key Files
- `src/auth/oauth.ts` — Main implementation file (modified)
- `src/auth/types.ts` — Type definitions (new)
- `tests/auth/oauth.test.ts` — Tests (partially written)
## Patterns to Follow
- Auth middleware pattern from `src/middleware/jwt.ts`
- Error handling style from `src/errors/`
## Gotchas Discovered
- The `UserService` caches aggressively — clear cache after auth changes
- Test DB needs `--runInBand` flag to avoid connection pool exhaustion
## Commands
- Build: `npm run build`
- Test: `npm test -- --runInBand`
- Verify: `npm run typecheck`
5. Continuation Instructions
## How to Continue
1. Read this handoff document
2. Check `git status` and `git log -5 --oneline` for current state
3. Start with [specific next task]
4. Reference [specific file] for the pattern to follow
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.

session-handoff is a skill published in the GitHub repository ArabelaTso/Skills-4-SE (252 stars, last pushed 22d ago), licensed Apache-2.0. It adds 32 tokens to every session and 717 once invoked, about $0.0002 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 2026-09-03.
