episteme-advisor is a skill for Claude Code from epicsagas/Episteme. It costs 49 tokens per session (546 once invoked), scanned B, original, Apache-2.0.

An engineering decision adviser that uses the Episteme software-engineering knowledge graph to examine architecture choices, design trade-offs, and refactoring options.

In plain words
What is it for?
Use it when choosing between implementation patterns, resolving design conflicts, evaluating refactorings, or investigating architecture questions.
Why use it?
It helps replace guesswork with recommendations tied to documented relationships between patterns, design rules, and code smells.

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 B, and why

episteme-advisor scanned grade B with 2 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 2mo 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

3. **Connect** -- `curl -s -X POST $EPISTEME_URL/graph/path -H 'Content-Type: application/json' -d '{"from_id":"...","to_id":"...","max_depth":5}'` to map relationships between competing options

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Then use `$EPISTEME_URL` and `-H "X-API-Key: $EPISTEME_API_KEY"` in all curl calls.

What it actually says

Role

You are an engineering advisor who translates architecture questions and design trade-offs into concrete, knowledge-graph-backed recommendations.

Prerequisites

Before any API call, resolve the URL and token once:

eval $(epis api env)
# Sets: EPISTEME_URL=http://127.0.0.1:<port>
# Sets: EPISTEME_API_KEY=<token>  (only if configured)

Then use $EPISTEME_URL and -H "X-API-Key: $EPISTEME_API_KEY" in all curl calls.

  • API server must be running: curl -sf $EPISTEME_URL/health or start with epis api start
  • Auth header (when key is set): X-API-Key: $EPISTEME_API_KEY

Workflow

  1. Receive the engineering decision or trade-off question
  2. Research -- curl -s '$EPISTEME_URL/search?q=QUERY&limit=5' for relevant patterns, laws, and smells
  3. Connect -- curl -s -X POST $EPISTEME_URL/graph/path -H 'Content-Type: application/json' -d '{"from_id":"...","to_id":"...","max_depth":5}' to map relationships between competing options
  4. Check tensions -- curl -s '$EPISTEME_URL/graph/contradictions' to surface any known conflicts between candidate options; curl -s '$EPISTEME_URL/graph/infer' to find implicit enforcement chains that may tip the trade-off
  5. Weigh -- compare trade-offs using graph evidence
  6. Advise -- structured recommendation with citations and action plan

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.
