A project-scanning setup step that identifies the repository, branch, programming language, and standard commands for testing, linting, formatting, and building.

Use it at the start of a session to load project details and set a consistent project identity across branches.

It gives other coding-agent tools verified context about the project instead of making them guess how the codebase works or which commands to run.

scan — Skill for Claude Code by datit309/supergraph

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add datit309/supergraph --skill scan

Clone the repo

git clone --depth 1 https://github.com/datit309/supergraph

Made for: Claude Code.

Or install supergraph, the plugin that ships this one along with the rest of its 42 skills, 7 agents, 6 hooks.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.

Model	Per session	Once invoked
Fable 5.1	$0.00018	$0.01145
Opus 5.5	$0.00007	$0.00458
Sonnet 5.5	$0.00004	$0.00229
Haiku 4.5	$0.00002	$0.00114

Security

Grade A, and why

scan 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 20d 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 — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/supergraph:scan

Load verified, project-scoped graph context once. Follow the shared references/codebase-memory-contract.md.

Announce: "📡 /supergraph:scan — loading project context..."

1. Detect project and branch

Use git branch --show-current, resolve the repository to an absolute path, and run bin/detect-project.sh when present. Otherwise detect commands from:

File	Type	Test	Lint	Format	Build
`package.json`	node	`npm test --`	`npx eslint .`	`npx prettier --write .`	`npm run build`
`Cargo.toml`	rust	`cargo test`	`cargo clippy`	`cargo fmt`	`cargo build`
`pyproject.toml`	python	`pytest`	`ruff check .`	`ruff format .`	`python -m build`
`go.mod`	go	`go test ./...`	`golangci-lint run`	`gofmt -w .`	`go build ./...`
`pubspec.yaml`	flutter	`flutter test`	`flutter analyze`	`dart format .`	`flutter build`

Ask when none match; never guess commands. Derive one stable CBM_PROJECT from the repository root name and retain it across branches. Default CBM_INDEX_MODE=moderate.

2. Verify provider and freshness

Call list_projects and find CBM_PROJECT.
If found, call index_status(project=CBM_PROJECT).
Treat missing project, changed branch, stale state, tool error, failed state, or status: "degraded" as requiring a new index.
TTL reuse (10m): If index_status returns status: "ready" and BRANCH matches .supergraph-env:BRANCH and now - CBM_INDEXED_AT < 600s and head_sha unchanged, reuse index — skip index_repository. Otherwise proceed to step 5. TTL check requires healthy index_status; never cache degraded/stale/error. On cache hit, still re-run index_status once to confirm liveness before get_graph_schema.
Call index_repository(repo_path=<absolute repo path>, name=CBM_PROJECT, mode=CBM_INDEX_MODE) when required (cache miss or stale/degraded). Require status: "indexed".
Re-run index_status; never claim reuse without a healthy response.
Call get_graph_schema(project=CBM_PROJECT) and get_architecture(project=CBM_PROJECT, aspects=["overview","layers","boundaries","clusters","hotspots"]) in parallel after verified index_status.
On cache hit, get_graph_schema and get_architecture may run in parallel immediately after TTL-passed index_status.

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.

scan is a skill published in the GitHub repository datit309/supergraph (21 stars, last pushed 3d ago), licensed MIT. It adds 18 tokens to every session and 1,145 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.
