sources

sources is a skill for Claude Code from gabrieldabbah/genesis. It costs 137 tokens per session (1,203 once invoked), scanned A, original, MIT.

A trusted-source and dependency-checking workflow for software research. It uses a project's source registry before web searches or adding libraries and tools.

In plain words
What is it for?
Use it when researching, finding documentation or API details, choosing dependencies, adding tools, or using /sources.
Why use it?
It reduces the risk of relying on unsupported information or documentation for the wrong software version.

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

sources 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.

Sources — trusted-first search & dependency vetting

Overview

A shown fact without a verified origin does not exist; an uncorroborated claim is a conjecture, not a fact. This skill applies that at the moment of searching and of choosing dependencies.

The registry is the project's docs/SOURCES.md; read it fresh each run — it is the source of truth for what to trust:

cat docs/SOURCES.md
sed -n '1,40p' CLAUDE.md                                    # the stack and versions to pin to

Invocation is the authorization for the search/vetting itself. The only thing surfaced to the operator is a genuine fork (a license conflict, a risky-but-wanted dependency, a missing trusted source for a critical fact) — and the operator approves the actual install or commit, as for any change.

A — When asked to search / research / look something up

  1. Trusted-first. Identify the domain and go to its Tier-1 source in SOURCES.md §3 before the open web (official language/framework docs, the standard, the package's own repo, this repo's own docs).
  2. Version-pin. Match the project's installed major version (lockfile plus CLAUDE.md) — docs for the wrong version are a silent trap.
  3. Corroborate & cite. Any Tier-2/3 finding is confirmed against a Tier-1 source before you rely on it; cite the origin inline. Ground every factorigin(fact) = None ⇒ drop it, never paraphrase a guess into a claim.
  4. Conjecture-flag the rest. Anything from an unlisted or Tier-3 source is presented as a conjecture with its falsifier, or withheld — never asserted as fact.
  5. Compound the registry. If you found a genuinely trustworthy source not in §3, add it (tier + one line on why) so the registry grows. For Claude/Anthropic model facts, defer to the claude-api skill.

B — When asked to add a dependency or tool

Run the SOURCES.md §4 vetting checklist — do not skip a box:

# real & canonical (not a typosquat): inspect the package's OWN registry page + linked repo
#   e.g.  npm view <pkg> repository.url   /   pip show <pkg>   /   cargo info <pkg>   — then open the real repo
# advisory-clean, BOTH ENDS (the current version if replacing, and the target you'd add) — cmd from SOURCES.md §5:
#   npm audit  /  pip-audit  /  cargo audit  /  govulncheck   + query OSV / GitHub Advisory for exact name+version

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.

sources is a skill published in the GitHub repository gabrieldabbah/genesis (4 stars, last pushed 1mo ago), licensed MIT. It adds 137 tokens to every session and 1,203 once invoked, about $0.0007 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.
