Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00032 | $0.01047 |
| Opus 5.5 | $0.00013 | $0.00419 |
| Sonnet 5.5 | $0.00006 | $0.00209 |
| Haiku 4.5 | $0.00003 | $0.00105 |
Grade A, and why
mitre-attack scanned grade A with 1 finding 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.

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

The opening of the file, as written. The whole thing — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.
MITRE ATT&CK Local Reference
Dataset
Local file: mitre-attack/enterprise-attack.json (~45 MB STIX 2.1 bundle).
First use — if the file is missing, run the bundled download script before any query:
./scripts/download-mitre.sh
The script is idempotent (skips if the file is already present) and supports --force for refresh. If scripts/download-mitre.sh is not present in the install (e.g. for plugin-only deployments), fall back to:
mkdir -p mitre-attack
curl -fsSL https://raw.githubusercontent.com/mitre/cti/master/enterprise-attack/enterprise-attack.json \
-o mitre-attack/enterprise-attack.json
This yields a STIX 2.1 bundle containing all Enterprise ATT&CK objects.
Querying the Dataset
The dataset is a JSON file with a objects array. Each object has a type field.
Find a technique by ID
cat mitre-attack/enterprise-attack.json | python3 -c "
import json, sys
data = json.load(sys.stdin)
tid = 'T1566' # Change as needed
for obj in data['objects']:
refs = obj.get('external_references', [])
for ref in refs:
if ref.get('external_id') == tid:
print(json.dumps(obj, indent=2))
break
"
List all techniques for a tactic
Tactics are mapped via kill_chain_phases[].phase_name:
reconnaissance,resource-development,initial-access,execution,persistenceprivilege-escalation,defense-evasion,credential-access,discoverylateral-movement,collection,command-and-control,exfiltration,impact
Find a threat group
# Groups have type "intrusion-set"
cat mitre-attack/enterprise-attack.json | python3 -c "
import json, sys
data = json.load(sys.stdin)
name = 'APT28' # Change as needed
for obj in data['objects']:
if obj.get('type') == 'intrusion-set':
aliases = obj.get('aliases', [])
if name in aliases or obj.get('name') == name:
print(json.dumps(obj, indent=2))
"
Map group to techniques
Groups link to techniques via relationship objects with relationship_type: "uses".
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.

mitre-attack is a skill published in the GitHub repository Liberty91LTD/cti-skills (36 stars, last pushed 4d ago), licensed MIT. It adds 32 tokens to every session and 1,047 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
