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 | $0.00199 | $0.03460 |
| Opus 5.5 | $0.00080 | $0.01384 |
| Sonnet 5.5 | $0.00040 | $0.00692 |
| Haiku 4.5 | $0.00020 | $0.00346 |
Grade C, and why
manage scanned grade C with 1 finding 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 11d 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Purpose
Personal-use Kindle DRM removal is a fragile multi-tool workflow with state mutations that, if forgotten, leave the user's machine in an awkward state (silent auto-update, stuck firewall rules, half-installed Calibre plugins). This skill captures the lifecycle as discrete reversible actions and tracks every upstream source that drifts independently (Amazon's Kindle for PC release cadence, Satsuoni's DeDRM_tools fork, Kindle_Key_Finder zip with rolling date in URL, techy-notes.com tutorial article).
Scope: Windows-only (Kindle for PC + KFXKeyExtractor are Windows binaries). Single-user. Books the user owns.
First step: probe current state
Probe current state on every invocation. Run scripts/status.sh and read the JSON output before deciding which action applies.
bash "${CLAUDE_PLUGIN_ROOT}/skills/manage/scripts/status.sh"
Output reports: Kindle for PC version, firewall rule presence, ICACLS deny presence, ~/Tools/Kindle_Key_Finder presence, ~/Downloads installer presence, Calibre install presence, Calibre plugin presence (best-effort), book count in My Kindle Content + Calibre Library.
Action router
| Action | When | What it does |
|---|---|---|
| (empty) | Default. Auto-detect from status | If pristine → recommend /kindle-dedrm:setup. If state OK + user mentioned new books → recommend sync. Otherwise emit status report |
setup |
First-time install | Delegates to the dedicated /kindle-dedrm:setup skill (uniform check/apply contract): provisioning walkthrough: download, install Kindle for PC 2.8.0, sign-in checkpoint, sync books, install Calibre plugins, run keyfinder, apply firewall + ICACLS lockdown |
sync |
New books purchased after initial setup | Disable firewall, prompt user to sync in Kindle, delete cached installer, re-enable firewall, re-run keyfinder |
update |
Periodic drift check | WebFetch tutorial URLs + gh API for upstream releases, diff against captured baselines in reference/sources.md, emit drift report. No mutations |
cleanup |
Decommission | Walk through every reversible mutation with per-item Y/N. Default (confirm-each) offers the firewall rule, ICACLS deny, keyfinder, and downloads; --soft limits to tools + downloads (keeps the firewall/ICACLS lock and Kindle for PC); --full also offers to uninstall Kindle for PC and remove Calibre plugins. The Calibre Library is never offered |
status |
Diagnostic | Same as default empty action |

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.

manage is a skill published in the GitHub repository melodic-software/claude-code-plugins (27 stars, last pushed today), licensed MIT. It adds 199 tokens to every session and 3,460 once invoked, about $0.0008 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
