orphograph-anchor

An audit-trail tool that creates Orphograph receipts for text, files, workspace memory, or consequential actions. It sends hashes rather than file contents, so the original data stays on the machine.

In plain words
What is it for?
Use it after sending messages, making payments, publishing files, or changing configuration; for daily memory snapshots; and to record or verify skill and prompt files.
Why use it?
It makes later changes detectable by recording the exact data or action record that existed at a particular time.

Token cost

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.

Security

Grade A, and why

orphograph-anchor 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 yesterday.

The scan reads SKILL.md. This mod also ships 1 executable file (orpho_agent_anchor.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Orphograph Anchor — agent audit trail

You have orpho_agent_anchor.py in this skill's directory. It sends only hashes to orphograph.com — file contents never leave the machine. A receipt proves the exact bytes existed at anchor time; it does not prove authorship, ownership, or that the action was correct. Never claim more.

Auth comes from ORPHO_API_KEY or ORPHO_PACK_TOKEN in the environment. If neither is set, tell the operator to get a key at https://orphograph.com and stop — do not retry.

When and how

1. After a consequential action — pipe a one-line record:

echo "2026-07-10T14:02Z sent invoice #42 to <recipient>" | \
  python3 orpho_agent_anchor.py anchor-text --label "action:invoice-42"

2. Daily memory snapshot (cron/heartbeat) — anchors one canonical manifest of every *.md memory file, so silent history edits are detectable later:

python3 orpho_agent_anchor.py anchor-memory ~/workspace --label "memory-daily"

3. Skill/prompt provenance — before sharing a skill file, anchor it and include the receipt id when you share; after receiving one, verify:

python3 orpho_agent_anchor.py anchor-file ./SKILL.md --label "skill:my-skill v3"
python3 orpho_agent_anchor.py verify <receipt_id> --file ./received_skill.md

Rules

  • Receipts append to .orphograph/receipts.jsonl — never delete or edit it.
  • On http_error 402/429, stop and notify the operator (out of credits or rate-limited); do not loop.
  • --dry-run first if unsure whether a file should be anchored at all.
Files

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.

Changes

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.

orphograph-anchor is a skill published in the GitHub repository Orphograph/Orphograph (0 stars, last pushed yesterday), licensed MIT. It adds 96 tokens to every session and 505 once invoked, about $0.0005 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.
