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 | $0.00015 | $0.00508 |
| Opus 5.5 | $0.00006 | $0.00203 |
| Sonnet 5.5 | $0.00003 | $0.00102 |
| Haiku 4.5 | $0.00002 | $0.00051 |
Grade B, and why
set scanned grade B 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 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
itself: `find ~/.claude/plugins -maxdepth 8 -type f -name What it actually says
Apply the user's requested per-session compaction thresholds: $ARGUMENTS
- Locate the compact-manager CLI. The path in the later steps
normally reads as an absolute path (script installs write it in).
If it instead still says
${CLAUDE_PLUGIN_ROOT}literally — plugin installs may not substitute command markdown — find the CLI file itself:find ~/.claude/plugins -maxdepth 8 -type f -name compact-manager -path "*/bin/*" 2>/dev/null(this handles versioned cache layouts, where a directory merely NAMED compact-manager has no bin/). If several paths match, use the most recently modified (ls -t). - Determine this session's id. The start-of-session compact-manager
status line bakes the exact
override <session-id> …command — prefer that id. Failing that, run"${CLAUDE_PLUGIN_ROOT}/bin/compact-manager" overviewand use the>-marked row's session id ONLY if itsupdatedage is seconds-old (>is recency, not identity); if it is older, ask the user rather than guessing. - Translate the user's request into the CLI's key=value form — keys
trigger,soft,hard(percentages like60%or fractions like0.6) andwindow(integer tokens) — and run:"${CLAUDE_PLUGIN_ROOT}/bin/compact-manager" override <session-id> key=value […]. To undo, pass--clearinstead of assignments; with no assignments at all the command just shows the current state. Relay the command's own output verbatim — it prints the stored override file and the resulting effective thresholds; do not re-derive them. - If the user's request doesn't map cleanly onto these keys (e.g. a
global or per-model change, or another session's), say so and point
at
~/.claude/compact-manager.jsoninstead of forcing it through this per-session mechanism.
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.
- 1mo ago First seen · 38 lines · 15 tokens per session scan B 39a12ccaec19
set is a command published in the GitHub repository msshives-gif/claude-plugins (2 stars, last pushed 7d ago), licensed MIT. It adds 15 tokens to every session and 508 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

init
First-time Archcore setup — wire host configs, measure the authored context, compose the full first-day seed in one preview, and create it on one confirm; import converts CLAUDE.md, AGENTS.md, rule files, ADRs, and docs into native documents; refresh adds new facts or drills into one domain.
document
Record the present state by mode — decision (ADR, RFC, rule), code (spec, doc, guide, scenario), or research (a ready report or one external material); a gate picks the document type.
mainframe-tickets-verify
This is a user-invocable command. Execute it only because the current invocation explicitly selected it. It takes no arguments: every invocation processes the complete current project queue awaiting independent verification.
lint-status
Show AgentLint status — coverage, effective policy, session activity.
edit
An interview-style command for editing the trigger words used by existing personas. Personas are predefined viewpoints, such as a developer, designer, or lawyer, that guide how work is approached.
update
Update Slime to the latest version.
