triage

triage is a skill for Claude Code from epicsagas/epic-harness. It costs 26 tokens per session (1,516 once invoked), scanned A, original, Apache-2.0.

A security-finding review workflow that checks whether a reported vulnerability can actually be exploited by an attacker and how serious its impact is.

In plain words
What is it for?
Tracing attacker-controlled input, checking whether it reaches vulnerable code, testing existing protections, and prioritizing remediation.
Why use it?
It filters out unconfirmed security reports and helps distinguish real, reachable problems from noise.

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

triage 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 9d 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.

Triage — Adversarial Vulnerability Validation

Iron Law

A vulnerability finding is not confirmed until an adversary would agree it's exploitable. Unvalidated findings are noise.

Process

Step 0: Load Inputs

Required inputs (in order of preference):

  1. VULN-FINDINGS.json from /vuln-scan
  2. Raw findings from /audit --security
  3. User-provided finding list

Optional:

  • THREAT_MODEL.md for threat scenario context
  • .harness/engagement.md for scope constraints

If no findings input exists, suggest: "Run /vuln-scan first to generate findings to triage."

Step 1: Adversarial Review

For each finding, challenge it from an attacker's perspective:

Exploitability Check
  1. Can input reach the vulnerable code? Trace the data flow from entry point to vulnerability.
  2. Can the attacker control the input? Distinguish between user-controlled vs. system-generated data.
  3. Is there a path to impact? Connecting the vulnerability to a security consequence (data leak, code exec, DoS).
  4. Are there bypasses for existing mitigations? WAF, input validation, CSP — all have bypass techniques.
Severity Validation
Criteria Adjust
Requires authentication Lower by 1 level
Requires specific permissions Lower by 1 level
Chained with another finding Raise by 1 level
Affects all users Raise by 1 level
No mitigation in place Raise by 1 level
Defense-in-depth exists Lower by 1 level
Classification
Class Meaning
CONFIRMED Exploitable with demonstrated path
LIKELY Exploitable with high confidence, minor gaps in proof
POSSIBLE Theoretical, needs more investigation
FALSE_POSITIVE Not exploitable with justification
ACCEPTED_RISK Known, documented, accepted by team

Step 2: Dependency Analysis

Check if findings chain together:

  1. Find pairs where finding A enables finding B (e.g., IDOR → data exposure)
  2. Mark chains — chained findings are more severe than individual findings
  3. Identify root causes — multiple findings from the same root cause should be grouped

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.

triage is a skill published in the GitHub repository epicsagas/epic-harness (18 stars, last pushed yesterday), licensed Apache-2.0. It adds 26 tokens to every session and 1,516 once invoked, about $0.0001 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 2026-08-30.
