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 | $0.00056 | $0.02146 |
| Opus 5 | $0.00028 | $0.01073 |
| Sonnet 5 | $0.00011 | $0.00429 |
| Haiku 4.5 | $0.00006 | $0.00215 |
Grade A, and why
cf-knowledge 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 2d 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 — 152 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.
Knowledge Management
Manage the CLEAR knowledge base: search, view, capture, index, link, deprecate, and supersede entries.
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 Use This Skill
| Trigger | Examples |
|---|---|
| View overview | "Show me the knowledge base status", "What's in the KB?" |
| Search or find entries | "Search knowledge for caching pattern", "Find decisions about auth" |
| View entry details | "Show me TD-015", "What does LES-003 say?" |
| Load into context | "Load knowledge for this workpackage" |
| Rebuild index | "Rebuild the knowledge index", "Reindex knowledge" |
| Capture knowledge | "Capture this decision", "Save this as a lesson learned" |
| Deprecate an entry | "Deprecate PAT-003", "This pattern is outdated" |
| Link or unlink | "Link TD-012 to WP-04", "Unlink LES-001" |
| Supersede an entry | "TD-005 replaces TD-002", "Supersede PAT-001 with PAT-007" |

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.

cf-knowledge is a skill published in the GitHub repository QBall-Inc/clear (3 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 56 tokens to every session and 2,146 once invoked, about $0.0003 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.

implement
End-to-end workflow for taking MCP work items from backlog to merged PR. Handles git branching, schema-driven planning, implementation, independent review, and PR creation. Composes spec-quality, review-quality, and schema-workflow skills into a single pipeline. Use when a user says "implement this", "work on this…
session-retrospective
Analyzes the current implementation run — evaluates schema effectiveness, delegation alignment, note quality, and plan-to-execution fit. Captures cross-session trends and proposes improvements when patterns repeat. Use after implementation runs, or when user says 'retrospective', 'session review', 'what did we learn'…

Launcher for the Ralph-style queue drain script — emits the right node ralph-loop.mjs invocation based on the user's filter and bounds. The actual loop runs as a Node script that spawns one claude -p --worktree per iteration; this skill is the configurator, not the loop. Use when a user says: drain the backlog, ralph…
prepare-release
End-to-end release automation — reads commits since last tag, infers semver bump, drafts changelog, creates release PR, merges it, waits for CI green, tags, and monitors the Docker build to completion. Use when the user says: prepare release, cut a release, bump version, create release PR, ship a new version, tag a…
