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 | $0.00099 | $0.00437 |
| Opus 5.5 | $0.00040 | $0.00175 |
| Sonnet 5.5 | $0.00020 | $0.00087 |
| Haiku 4.5 | $0.00010 | $0.00044 |
Grade A, and why
extract-plan-md 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 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.
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.
What it actually says
Extract Plan MD
Sync plan.md with plan.json content. Use this skill after ANY edit to plan.json.
IMPORTANT: When to Use
REQUIRED after plan.json edits:
- After using the Edit tool on plan.json → run this skill to sync plan.md
- After programmatically modifying plan.json content field
- After plan amendments, task status changes, or any plan modifications
Also use for:
- User requests to sync/extract/convert plan.json to markdown
- Reviewing a plan outside of the JSON structure
- Sharing the plan with others who don't need the structured JSON fields
Usage
To sync plan.md with plan.json:
python3 ${CLAUDE_SKILL_DIR}/scripts/extract.py /path/to/plan.json
The script:
- Reads the plan.json file
- Extracts the
contentkey (which contains the full markdown plan) - Fixes any escaped line breaks (
\n-> actual newlines) - Writes to
plan.mdin the same directory as the plan.json
Examples
After editing plan.json, sync plan.md:
python3 ${CLAUDE_SKILL_DIR}/scripts/extract.py .closedloop-ai/work/plan.json
# Updates .closedloop-ai/work/plan.md to match
Extract from a specific plan:
python3 ${CLAUDE_SKILL_DIR}/scripts/extract.py ~/work/plan.json
# Creates/updates ~/work/plan.md
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.
