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 | $0.00039 | $0.03154 |
| Opus 5 | $0.00019 | $0.01577 |
| Sonnet 5 | $0.00008 | $0.00631 |
| Haiku 4.5 | $0.00004 | $0.00315 |
Grade A, and why
session-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 4d 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 — 222 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLI Usage: When unsure about a CLI's interface or flags, run it with
--helpfirst. Do NOT attempt to discover functionality by reading plugin source code — doing so leads to incorrect execution from assumptions made without context of the holistic flow.
Session Management Skill
Purpose
This skill provides guidance for Claude on managing session lifecycle in the CLEAR framework. It explains token thresholds, handoff procedures, and how to manually invoke session operations.
Plugin Root Resolution
CLI commands in this skill reference $CLEAR_PLUGIN_ROOT — a .claude/settings.json env var the shell expands. The SessionStart hook persists it, but settings env vars load at session launch, so on a brand-new consumer's first session (before its next restart) the variable is empty and node "$CLEAR_PLUGIN_ROOT/build/..." fails with MODULE_NOT_FOUND.
First-session bootstrap — if $CLEAR_PLUGIN_ROOT is empty, set it inline in the same Bash call as the CLI (each Bash call is a fresh shell, so a separate export would not carry over):
export CLEAR_PLUGIN_ROOT="${CLEAR_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}"
Prepend it to the CLI in one shell line: export CLEAR_PLUGIN_ROOT="${CLEAR_PLUGIN_ROOT:-${CLAUDE_PLUGIN_ROOT}}"; <node "$CLEAR_PLUGIN_ROOT/build/..." command>. ${CLAUDE_PLUGIN_ROOT} resolves in this SKILL.md body to the actually-loaded plugin path; once the consumer restarts, $CLEAR_PLUGIN_ROOT is populated and the assignment is a harmless no-op. Reference files are left unchanged.
When to Take Action vs. Just Answer
TAKE ACTION (run scripts) when user says:
- "check my token usage" / "how much context have I used"
- "prepare session handoff" / "prepare for handoff"
- "end session early" / "wrap up this session"
- "initialize session tracking"
JUST READ FILES (no scripts) when user asks:
- "have we completed the handoff?" → Check
.clear/state/session.json - "what was in the last handoff?" → Read
.clear/sessions/*.md - "how many sessions have we had?" → Read
.clear/state/session-history.json - "what happened in session 14?" → Read the specific session file
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-management is a skill published in the GitHub repository QBall-Inc/clear (3 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 39 tokens to every session and 3,154 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.

session
Use when significant work wraps up — a feature shipped, a bug fixed, a research thread finished, before the user steps away — and also mid-task as a checkpoint before a long run risks context compaction (it updates the same session note + handoff, never spawns a duplicate).
