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 5.1 | $0.00039 | $0.00823 |
| Opus 5 | $0.00019 | $0.00411 |
| Sonnet 5 | $0.00008 | $0.00165 |
| Haiku 4.5 | $0.00004 | $0.00082 |
Grade A, and why
handoff-management 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 6d 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Handoff Management Skill
Handoffs capture work-in-progress state, enabling seamless session continuity. Unlike learnings (permanent knowledge), handoffs capture ephemeral state: what's done, what's pending, and what's blocking progress.
When to Use Handoffs
Save Progress
- Before ending a session with incomplete work
- Before context compaction (automatic via PreCompact hook)
- When switching between tasks
Resume Work
- Starting a new session on existing work
- After context was cleared or compacted
- Picking up where you left off
Handoff Commands
Create a Handoff
# Basic handoff
uv run cclaude handoff create
# With specific tasks
uv run cclaude handoff create \
--completed "Implemented auth middleware" \
--completed "Added JWT validation" \
--pending "Write integration tests" \
--pending "Add password reset flow" \
--blocker "Need API credentials for OAuth" \
--context "Using RS256 for token signing"

Handoff Format
Handoffs are stored as markdown with YAML frontmatter:
---
session_id: abc-123
timestamp: 2025-12-27T14:30:00+00:00
---
## Completed
- Implemented auth middleware
- Added JWT validation
## Pending
- Write integration tests
- Add password reset flow
## Modified Files
- src/auth/middleware.py
- src/auth/jwt.py
## Blockers
- Need API credentials for OAuth
## Context
Using RS256 for token signing. The auth service expects tokens
in the Authorization header, not cookies.

Best Practices
When Creating Handoffs
-
Be specific about pending tasks
- Bad: "Finish auth"
- Good: "Write integration tests for JWT refresh flow"
-
Document blockers clearly
- What's blocking?
- What's needed to unblock?
- Who can help?
-
Include relevant context
- Key decisions made
- Important file paths
- Configuration details
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.

handoff-management is a skill published in the GitHub repository aaronb305/claude-cortex (2 stars, last pushed 5mo ago), licensed MIT. It adds 39 tokens to every session and 823 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 2026-08-31.
