grafel-patterns-discover

grafel-patterns-discover is a skill for Claude Code, Codex from cajasmota/grafel. It costs 0 tokens per session (903 once invoked), scanned A, original, MIT.

A codebase-audit procedure that finds recurring patterns and conventions in a registered group of repositories. It updates the pattern store without rewriting the project's documentation.

In plain words
What is it for?
Use it to refresh a pattern store, audit repository conventions, or check what new patterns have emerged. It requires a registered group and up-to-date Grafel graph files.
Why use it?
It lets a team refresh its understanding of coding conventions without triggering a full documentation-generation process. It also checks that the repositories have current indexed data before auditing them.

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-discover 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 10d 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.

grafel-patterns-discover

Standalone agent skill for pattern discovery without doc generation. Use when the user wants a fresh pattern audit of an indexed group but does NOT want /generate-docs to regenerate prose.

This skill is the secondary entry point described by ADR-0018; the primary one is /generate-docs Phases 1 + 4.

When to use this skill

  • "Refresh my pattern store."
  • "Audit our codebase conventions without touching the docs."
  • "Did anything new converge since the last /generate-docs run?"

Do NOT invoke this skill on first install when no group is registered, when grafel status reports indexing in progress, or as part of /generate-docs (that path runs its own Phase 1 + 4 already).

Inputs the skill expects

  • A registered group resolvable via grafel_orient (view=me).
  • An up-to-date <repo>/.grafel/graph.json per repo. If any repo's graph is stale, stop and tell the user to run grafel rebuild <group> first.
  • Read access to <group>/.grafel/patterns.json (the pattern store) and patterns-config.json (thresholds — defaults applied when absent).

Procedure

Step 1 — Slice the codebase

Dispatch one subagent per top-level module cluster (as returned by grafel_orient (view=clusters)). Each subagent receives:

  • Its cluster's entity ID set.
  • A read-only copy of the existing pattern store (so it can skip shapes already covered).

Subagents do NOT share state during Step 1.

Step 2 — Per-subagent discovery (Phase 1 in ADR-0018 terms)

Each subagent scans its slice for structural recurrences:

  1. Group entities of the same kind that share file-path prefix, naming convention, or annotation set.
  2. If a candidate shape appears ≥ per_subagent_threshold times (default 2) within the slice, emit a PatternCandidate via grafel_patterns(action=record, as_candidate=true, ...).
  3. Include all observed entities as exemplars in the candidate payload — the coordinator needs the exemplar set for clustering.

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-discover is a skill published in the GitHub repository cajasmota/grafel (15 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 903 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.
