Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00101 | $0.01904 |
| Opus 5.5 | $0.00040 | $0.00762 |
| Sonnet 5.5 | $0.00020 | $0.00381 |
| Haiku 4.5 | $0.00010 | $0.00190 |
Grade A, and why
agent-memory-protocol 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.
How it starts
The opening of the file, as written. The whole thing — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Named Memory Protocol
How a named workflow works the gutt knowledge graph as itself: register a memory
identity, recall its own scope before the group's, and tag every org write it makes
so the next run can find it. This layers workflow identity on top of
memory-search (how to read) and memory-capture (how to write). The identity
convention — naming, registration, tagging, recall order, guard rails — lives in
one normative place: references/agent-identity.md. This file is the operative
digest; on any conflict, the reference wins.
Use this for a named memory-writing workflow: either an agent or a skill whose
contract declares a stable identity. For a skill, declare the base identity in
frontmatter as metadata.memory-identity and repeat the operative rules under an
exact ## Memory identity heading. Writing from the main session with no named
workflow identity is just memory-capture — no registration and no tagging.
Finding the scope bound to this directory (do this before step 1)
The registered name carries a --<scope> suffix, and the first place to look for its
value is the binding a person set with /gutt-pro:agent-scope. You cannot run that
command to ask — it only takes effect when a human types it — so read the stored value
directly:
<DATA_DIR>—${CLAUDE_PLUGIN_DATA}, interpolated into this sentence for you. Do not pass$CLAUDE_PLUGIN_DATAthrough to a shell and do notexportit: only hooks are given it, so it expands to nothing in a command you run.- Read
<DATA_DIR>/config.jsonand look underprojects. The key is the name Claude Code gives this project's transcript directory, which you can derive from your working directory: resolve its symlinks, then replace every path separator, drive-letter colon,.and_with a single-— each character becomes its own dash, so two adjacent ones yield--(this is not the run-collapsing rule scope values are normalised with). So/Users/me/my_appis-Users-me-my-app,/Users/me/.config/appis-Users-me--config-app, and on WindowsC:\dev\my.appisC--dev-my-app. Takeprojects.<that key>.agentScope.value.- Resolve the symlinks first (
pwd -P): on macOS/tmpand/varare links into/private, and the unresolved spelling gives a key that never matches. - Match the key exactly. If nothing matches, treat it as unbound and fall through — never pick the closest-looking entry, because a wrong match binds this directory to another one's identity, permanently.

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.

agent-memory-protocol is a skill published in the GitHub repository iBrain-BVBA/gutt-claude-code-plugin (5 stars, last pushed 1mo ago), licensed MIT. It adds 101 tokens to every session and 1,904 once invoked, about $0.0004 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 2026-08-31.
