Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00029 | $0.00259 |
| Opus 5.5 | $0.00012 | $0.00104 |
| Sonnet 5.5 | $0.00006 | $0.00052 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
diff 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 1mo 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.
What it actually says
Run the diff-handoff script (pass the user's timestamp $ARGUMENTS if given; otherwise it compares against the previous save automatically):
- Linux/macOS/WSL/Git-Bash:
bash "${CLAUDE_PLUGIN_ROOT:-.claude}/skills/handoff-revive/scripts/diff-handoff.sh" [timestamp] - Windows PowerShell:
$r = if ($env:CLAUDE_PLUGIN_ROOT) { $env:CLAUDE_PLUGIN_ROOT } else { ".claude" }; powershell -ExecutionPolicy Bypass -File "$r/skills/handoff-revive/scripts/diff-handoff.ps1" [-Timestamp <timestamp>]
Then, in the user's language (read .claude/handoff/lang), present the output and add a 1–2 sentence progress summary: what moved from todo/wip to done, how next_action changed, and any new lessons_learned. + lines were added since the snapshot, - lines were removed.
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.

diff is a command published in the GitHub repository sofumel/claude-handoff-revive (8 stars, last pushed today), licensed MIT. It adds 29 tokens to every session and 259 once invoked, about $0.0001 per session on Opus 5.5. 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.
Other commands, from other repositories
remember
Save the current session to persistent context memory.
recall
Search past sessions stored in context memory.
audit
Audit .flow/memory/ entries against the current codebase — Keep / Update / Consolidate / Replace / Delete / Harden per entry.
memory-migrate
Migrate legacy .flow/memory/{pitfalls,conventions,decisions}.md flat files into the categorized YAML schema — host agent classifies each entry directly.
memory
USE WHEN recalling past decisions, storing new insights, forgetting stale memories, linking memories, or reviewing pending memory proposals. Groups recall | learn (with optional --save-context) | forget | relate | propose.
analyze-context
USE WHEN you want to analyze project context before starting work on a task. Calls context + recall, then synthesizes goals, decisions, gotchas, and relevant memories into a pre-task brief.
