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 5.1 | $0.00010 | $0.00303 |
| Opus 5.5 | $0.00004 | $0.00121 |
| Sonnet 5.5 | $0.00002 | $0.00061 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade B, and why
half-clone 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.
1. Get the current session ID and project path: `tail -1 ~/.claude/history.jsonl | jq -r '[.sessionId, .project] | @tsv'` What it actually says
Clone the later half of the current conversation, discarding earlier context to reduce token usage while preserving recent work.
Steps:
- Get the current session ID and project path:
tail -1 ~/.claude/history.jsonl | jq -r '[.sessionId, .project] | @tsv' - The script is bundled at
scripts/half-clone-conversation.sh - Preview the conversation to verify the session ID:
scripts/half-clone-conversation.sh --preview <session-id> <project-path>- Check that the first and last messages match the current conversation
- Run the clone:
scripts/half-clone-conversation.sh <session-id> <project-path>- Always pass the project path from the history entry, not the current working directory
- Tell the user they can access the half-cloned conversation with
claude -rand look for the one marked[HALF-CLONE <timestamp>](e.g.,[HALF-CLONE Jan 7 14:30]). The script automatically appends a reference to the original conversation at the end of the cloned file.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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 · 23 lines · 10 tokens per session scan B 39d896f139d1
half-clone is a skill published in the GitHub repository qGolem/orc (5 stars, last pushed 7mo ago), licensed MIT. It adds 10 tokens to every session and 303 once invoked, about $0.0000 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.

context-driven-development
Use this skill when working with Conductor's context-driven development methodology, managing project context artifacts, or understanding the relationship between product.md, tech-stack.md, and workflow.md files.
knowledge-manager
Loads relevant patterns and known errors before track planning. Searches conductor/knowledge/ for solutions we've used before and errors we've encountered. Injects findings into the planner prompt to prevent reinventing solutions and repeating mistakes. Triggered automatically by orchestrator before PLAN step.
context-loader
Load project context efficiently for Conductor workflows. Use when starting work on a track, implementing features, or needing project context without consuming excessive tokens.
memory
Use before the first memory verb — read or write — whenever the orchestrator is about to touch memory as this turn's subject: deciding what persists, searching, curating, or triaging what a session injected at start.
session-reflection
Use when the user asks to reflect on a session or to compact it -- "reflexionemos sobre la sesión", "cerremos esto", "guardemos lo que aprendimos", "compactemos", "compacta", "let's reflect on this session", "wrap up this session", "compact the session" -- or when closing substantial work: the orchestrator reconciles…
