context

context is a skill for Claude Code from o-samoilov/quasar-graph. It costs 159 tokens per session (2,183 once invoked), scanned A, original, MIT.

A project-connection tool that links the current codebase to a backend graph of related projects and keeps those connections available during the session. A project graph is a map showing how projects and services relate to one another.

In plain words
What is it for?
It is for answering architecture questions about the current project, finding related services or repositories, and optionally loading confirmed neighboring projects for inspection.
Why use it?
Understanding a service often requires knowing which other projects call it or depend on it. This provides those structural connections without changing the graph, while reading neighboring source code requires confirmation.

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

context 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 7d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/quasar-graph:context

Bind the project you are working in to its node in a backend graph, load its connections into the session, and keep them available for the rest of the work: structural questions are answered from the graph, and — only after explicit confirmation — the agent reads the source code of neighbor projects.

This is the in-session counterpart to research: research is a standalone Q&A loop over a manually picked project + graph; context binds to the current project automatically and then stays in the background of normal work. It is read-only w.r.t. the graph — it never calls build_graph / push_graph / write_node_manifests / create_graph / pull_graph and writes nothing under .quasar-graph/. The only things it may change on disk are cloning confirmed missing neighbor repos into base_dir (Phase 2) and the saved keys in ~/.quasar-graph/config.json; the binding cache in ~/.quasar-graph/cache/bindings.json is maintained by the bind_context tool it calls. It requires the quasar-graph MCP server (the graph lives on the backend — there is no offline mode).

Optional argument: /quasar-graph:context <path> binds that directory instead of the current working directory. Everything below calls it the target directory.

Conventions

Read references/conventions.md at the quasar-graph plugin root before acting. It defines the action vocabulary this skill is written in (dispatch a sub-agent, load a skill, selection prompt, …) with its per-harness degradations, the selection UI rules, the login retry flow, and the repo identity & binding cache rules.

In this skill the selection UI covers candidate nodes in Phase 0 (from bind_context's candidates list on status: ambiguous; label = node name + graph name, description = the node's own description) and every look-into-neighbor confirmation in Phase 2; free-form inputs (the base_dir path) stay plain text.

Phase 0 — Bind

Goal: resolve which graph node is the current project and load that graph into context (NOT to disk).

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.

context is a skill published in the GitHub repository o-samoilov/quasar-graph (3 stars, last pushed 25d ago), licensed MIT. It adds 159 tokens to every session and 2,183 once invoked, about $0.0008 per session on Opus 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.
