Engagement Memory (cross-engagement learning)
When to Activate
- At recon/weaponize: recall what already worked against this target class / tech stack.
- At report: persist each
[CONFIRMED]finding as a reusable pattern (ranked by impact). - Periodic housekeeping: compact the pattern DB / rotate the audit log.
Model
Append-only JSONL store (~/.claude/engagement-memory/patterns.jsonl, override $ENGAGEMENT_DB).
Three record types in their own files so they never mix: patterns (patterns.jsonl),
target profiles (profiles.jsonl), audit log (audit.jsonl, disposable). A pattern is keyed
by (target, vuln_class, technique), ranked by severity / CVSS / confidence (real impact, never
payout), and carries a lifecycle status (proposed/active/stale/deprecated/...). Recall is an
explicit top-N query (anti-context-bloat). Duplicates merge (count bumped, most-recent status
wins), never blind-discarded; compact runs automatically over a size threshold and stays lossless.
TTL stale patterns and deprecated/rejected ones drop out of default recall but are kept.
Commands
# RECALL — relevance-ranked (stdlib BM25 + aliases), active-only by default
python skills/engagement-memory/scripts/pattern_db.py match --vuln-class ssrf --query "imds metadata" --tech-stack aws
# INJECT — budgeted prior-intel card for a phase (top-N, byte-capped; $ENGAGEMENT_MEMORY_MODE=auto|debug|off)
python skills/engagement-memory/scripts/pattern_db.py inject --vuln-class ssrf --query imds --max-bytes 1500
# RECORD a confirmed finding (flags or finding JSON). A key collision needs --resolve update|merge|reject|force.
python skills/engagement-memory/scripts/pattern_db.py record --target acme.com --vuln-class ssrf \
--cwe CWE-918 --attack-id T1190 --severity high --cvss 9.1 --tech-stack nginx,aws --technique "metadata theft"
python skills/engagement-memory/scripts/pattern_db.py record --json '<finding json from validate_findings>'
# LIFECYCLE + cross-client
python skills/engagement-memory/scripts/pattern_db.py promote --target acme.com --vuln-class ssrf --technique "metadata theft" [--global]
python skills/engagement-memory/scripts/pattern_db.py deprecate --target acme.com --vuln-class ssrf --technique "metadata theft"
python skills/engagement-memory/scripts/pattern_db.py match --vuln-class ssrf --include-global # add sanitized cross-client TTPs
# PROFILES + housekeeping + observability
python skills/engagement-memory/scripts/pattern_db.py profile --target acme.com --tech-stack nginx,aws --endpoints /api,/admin
python skills/engagement-memory/scripts/pattern_db.py recall-profile --target acme.com
python skills/engagement-memory/scripts/pattern_db.py compact # manual lossless dedup-merge
python skills/engagement-memory/scripts/pattern_db.py stats # patterns by class + profile count
python skills/engagement-memory/scripts/pattern_db.py audit-stats # action log: by tool/action/outcomeOr use the /engage.memory command (recall | inject | record | promote | deprecate | gc | stats).
OPSEC & Detection
| Concern | Note |
| Secrets at rest | Stores technique + CWE/CVSS + an evidence reference, never loot. A secret-input guard rejects evidence_ref/source that look like inline secrets (private keys, password=, AKIA, JWTs, tokens) — store a path; rotate the exposed credential, don't just delete. |
| Cross-client bleed | Per-client isolation is the default ($ENGAGEMENT_DB). The shared global store is opt-in (promote --global / record --global) and sanitized (target + evidence blanked); recall it only with --include-global. |
| Trust | New auto-captures can be proposed; only confirmed/reviewed findings are active. A key collision is review-gated (--resolve), not silently merged. |
| Auditability | Every record/match/compact/promote — and every refused line (denial) — is written to audit.jsonl (rotated by discard, with a retention-gap marker). The append-only patterns journal + audit log ARE the history. |
| Integrity | Records carry schema_version; malformed/type-poisoned/foreign lines are skipped on read, never trusted. |

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
