pce-graph

pce-graph is a skill for Claude Code from CAPHTECH/pce-memory. It costs 45 tokens per session (746 once invoked), scanned A, original, MIT.

A knowledge-graph tool for recording software components, services, APIs, databases, and concepts, along with the relationships between them. A knowledge graph is a connected map of facts and links.

In plain words
What is it for?
It helps create and search entities, record relationships, query dependency patterns, and visualize connections in the pce-memory knowledge graph.
Why use it?
It gives developers a structured way to find how parts of a codebase or system relate instead of relying on scattered notes.

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

pce-graph 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.

PCE Graph - Knowledge Graph Operations

Operate on the pce-memory knowledge graph (entities and relations).

Argument Parsing

Parse $ARGUMENTS:

  • entity [name] [type] → Create/search entity
  • relation [from] [to] [type] → Create relation
  • query [pattern] → Search graph
  • No arguments → Interactive guide

Entity Operations

Creating Entities

Register important codebase components as entities.

pce_memory_upsert_entity({
  id: "entity-unique-id",
  type: "component|module|api|database|service|concept",
  name: "Display name",
  properties: { ... }  // Optional additional info
})

Entity Type Guide

See entity-relation-patterns.md.

Type Purpose Examples
component Software component AuthService, UserController
module Module/package pce-boundary, pce-embeddings
api API endpoint POST /api/claims
database Data store DuckDB, Redis
service External service OpenAI API, GitHub
concept Concept/pattern State Machine, CRDT

Querying Entities

pce_memory_query_entity({
  type: "component",     // Filter by type
  name_pattern: "Auth*"  // Filter by name pattern
})

Relation Operations

Creating Relations

Register relationships between entities.

pce_memory_upsert_relation({
  from_id: "entity-a",
  to_id: "entity-b",
  relation_type: "depends_on|implements|contains|calls|stores_in",
  properties: { ... }
})

Relation Type Guide

Type Meaning Example
depends_on Dependency AuthService depends_on JWTLibrary
implements Implementation UserController implements IUserAPI
contains Containment CoreModule contains StateManager
calls Invocation Handler calls Repository
stores_in Persistence target ClaimStore stores_in DuckDB

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.

pce-graph is a skill published in the GitHub repository CAPHTECH/pce-memory (3 stars, last pushed 6mo ago), licensed MIT. It adds 45 tokens to every session and 746 once invoked, about $0.0002 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.
