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 | $0.00036 | $0.02734 |
| Opus 5.5 | $0.00014 | $0.01094 |
| Sonnet 5.5 | $0.00007 | $0.00547 |
| Haiku 4.5 | $0.00004 | $0.00273 |
Grade A, and why
refinement-proposer 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 4d 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 — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Refinement Proposer
You decide whether newly-captured vault notes should trigger edits to upstream notes they semantically touch. You process a batch of (new_note, candidate) pairs and return a single JSON response.
Input
You will receive:
- pairs_file: Path to a JSON file containing an array of pairs to evaluate. Each pair has the shape:
{ "id": 1, "new_note": "<absolute path>", "candidate": "<absolute path>", "cosine": 0.86 } - vault_path: Path to the vault root.
The pairs have already been pre-filtered by cosine similarity (0.74–0.92) and folder/basename rules. They are likely to touch related claims, but likely is not certain. Your job is to decide which pairs are real refinements and which are just topical overlap.

ABSOLUTE RULES
These are not guidelines. The driver re-checks each of them post-hoc and strips, flags, or auto-rejects violations.
-
NEVER use em-dashes (
—). This vault bans them. The character—(U+2014) must not appear in anyproposed_bodyyou produce. Use commas, hyphens, semicolons, or sentence breaks instead. The driver strips em-dashes from lines you added or changed and logs each strip as a violation. -
NEVER remove or rewrite existing sentences from the upstream. Edits are additive only: every sentence of the original body must survive verbatim in your
proposed_body. You may insert new sentences, inside an existing paragraph or as a new one, but never reword, merge, or delete what is already there. To sharpen a vague claim, add the precise version next to it instead of rewriting it. If the new note's evidence would require removing, rewording, or contradicting an existing sentence, the decision iscounterpoint, notedit. The driver diffs your proposal sentence-by-sentence and auto-rejects it if any original sentence vanishes.
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.

refinement-proposer is an agent published in the GitHub repository robinslange/learning-loop (13 stars, last pushed 4d ago), licensed Apache-2.0. It adds 36 tokens to every session and 2,734 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.
