grafel-patterns-sync

grafel-patterns-sync is a skill for Claude Code, Codex from cajasmota/grafel. It costs 0 tokens per session (1,079 once invoked), scanned A, original, MIT.

A two-way synchronisation tool between grafel's pattern store and a repository's CLAUDE.md or AGENTS.md instructions. These files contain guidance for AI coding agents, and the sync preserves content outside its marked section.

In plain words
What is it for?
Use it to update agent instructions from stored patterns, import patterns from those instruction files, or reconcile both sources.
Why use it?
It keeps recorded coding patterns and repository instructions aligned without overwriting unrelated text. Private anti-patterns are kept out of version-controlled files.

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

grafel-patterns-sync 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 6d 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 — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.

grafel-patterns-sync

Bidirectional sync between the per-group pattern store and a repo's version-controlled CLAUDE.md / AGENTS.md. Marker-wrapped, idempotent, and privacy-aware.

This skill is the export-side surface described by ADR-0018. Privacy boundary: any anti-pattern with private=true MUST NOT be written to a version-controlled file, regardless of which direction the sync is running.

When to use this skill

  • "Update CLAUDE.md with our latest patterns."
  • "Pull patterns from this repo's CLAUDE.md into the store."
  • "Reconcile CLAUDE.md and the pattern store."

Do NOT invoke this skill if no patterns have been recorded yet (run /generate-docs or /grafel-patterns-discover first), or if the user has manually edited the marker-wrapped block — surface the edits as candidates first via the import path.

Marker block format

The sync block lives inside this pair of HTML-comment markers (matching the gfleet upsertAgentRulesBlock convention established in AI-Memory):

<!-- grafel:patterns:start v=1 -->
... pattern index ...
<!-- grafel:patterns:end -->

Content outside the markers is user territory and is preserved byte-for-byte.

The block is a SHORT INDEX, not the full pattern markdown. Each pattern entry is a one-liner:

- **<trigger>** — confidence <c>, <n> observations. [Full recipe](docs/patterns/<category>/<id>.md)

The full recipe lives at the linked path (written by /generate-docs Phase 6). A human reading CLAUDE.md can click through; an agent reading the block has every trigger summarised in one place.

Inputs

  • The target CLAUDE.md / AGENTS.md file path (per-repo, version-controlled).
  • The group name (defaults to the registered group when only one exists).
  • The current pattern store, loaded via grafel_patterns(action=query, include_candidates=false) or via the CLI's direct file read.

Procedure

Step 1 — Resolve the file

If the file does not exist, the skill creates it containing only the marker block. If it exists with no markers, the block is appended after a blank-line separator. If it exists with markers, the block contents are replaced; everything outside the markers is preserved.

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.

grafel-patterns-sync is a skill published in the GitHub repository cajasmota/grafel (12 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,079 tokens. 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.
