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.

What it costs to keep this loaded
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 | $0.00028 | $0.00515 |
| Opus 5.5 | $0.00011 | $0.00206 |
| Sonnet 5.5 | $0.00006 | $0.00103 |
| Haiku 4.5 | $0.00003 | $0.00052 |
Grade A, and why
ledger 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
/ops:ledger
Load ops-rules before acting. Public repo (no personal data). Outbound: one draft → one approval → one send. If AskUserQuestion / Workflow are missing, follow Rule 10 in ops-rules (Hermes: numbered options / two-turn Telegram card; delegate_task).
Single source of truth shared between claude-ops (Mac) and Perplexity (off-Mac).
Stored at ~/.claude-ops/ledger.jsonl and mirrored to Notion DB "Ops Ledger".
Usage
# Default: human digest of last 24h
/ops:ledger
# What needs owner's attention right now?
/ops:ledger awaiting
# What did Perplexity do while I was at the gym?
/ops:ledger query --source perplexity --since -PT4H
# What's been touched on this Gmail thread?
/ops:ledger query --claim-key gmail:thread:19e690a55d213f52
Behavior
Wraps ~/.claude-ops/bin/ledger (the CLI from this skill). Always reports:
- Awaiting owner (top of digest, sorted newest first)
- Drafted by either system (needs send / merge / approve)
- Done autonomously in last 24h, grouped by source (claude-ops, Perplexity)
- Skipped or expired claims
Conventions every command in this plugin follows
Before doing real work, run:
~/.claude-ops/bin/ledger query --claim-key "$CLAIM_KEY" --since -PT24H
If result has any entry with status in (in_progress, done, drafted, awaiting_user),
SKIP — the other system already handled it. Don't duplicate.
After doing work:
~/.claude-ops/bin/ledger claim --claim-key "$CLAIM_KEY" --kind <kind> --brand <brand> \
--title "<title>" --source claude-ops
# ... do work ...
~/.claude-ops/bin/ledger resolve <id> --status done|drafted|awaiting_user
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.

ledger is a skill published in the GitHub repository Lifecycle-Innovations-Limited/claude-ops (545 stars, last pushed 2d ago), licensed MIT. It adds 28 tokens to every session and 515 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
