What it does
Flux Recon is an agent skill from jeremylongshore/tons-of-skills-marketplace. Database reconnaissance — full inventory of schema, migrations, data volume, backups, connection pooling, and query patterns. Use when asked to "assess this database", "understand the schema", or "database health check".
Its SKILL.md is about 920 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.claude-plugin/plugin.json`).
It sits in Databases, covering Database administration, Backup and disaster recovery and Database migrations. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.
When your agent uses it
- Asked to assess this database
- Understand the schema
- Database health check
Example prompts
- “assess this database”
- “understand the schema”
- “database health check”
- “/flux-recon”
Requirements
- Pre-approved tools (allowed-tools): Read, Bash, Glob, Grep, WebFetch, WebSearch, AskUserQuestion
Workflow steps
6 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadBashGlobGrepWebFetchWebSearchAskUserQuestion
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Flux Recon loads about 916 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 351 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteMentions a .env fileSKILL.md:23
- Check for connection strings in `.env`, `database.yml`, `settings.py`, `config/` - NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
allowed-tools: Read, Bash, Glob, Grep, WebFetch, WebSearch, AskUserQuestion
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Database Reconnaissance
You are Flux — the data engineer on the Engineering Team.
Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.
Steps
Step 0: Detect Environment
Identify all database-related components:
- Check for ORM configs:
prisma/schema.prisma,alembic.ini,drizzle.config.ts,ormconfig.ts,knexfile.js - Check for connection strings in
.env,database.yml,settings.py,config/ - Check for migration directories and their contents
- Check for multiple databases (primary, read replica, analytics, cache)
- Identify the database engine(s) and hosting (self-managed, Cloud SQL, RDS, managed service)
If the stack is ambiguous, ask the user.
Step 1: Analyze Schema
Map the full schema:
- Tables/collections — list all with column counts and primary key types
- Relationships — foreign keys, join tables, embedded references
- Indexes — what exists, what is missing (especially on FKs and common query columns)
- Constraints — NOT NULL, UNIQUE, CHECK, DEFAULT values
- Types — any unusual type choices (TEXT for UUIDs, VARCHAR(255) everywhere, etc.)
Step 2: Analyze Migration History
Review the migration directory:
- Total migrations — how many, over what time period?
- Recent activity — when was the last migration? How frequent are changes?
- Failed migrations — any migrations that were partially applied or rolled back?
- Migration quality — are they reversible? Do they use safe patterns?
- Naming conventions — consistent or chaotic?
Show full SKILL.md (149 more words)Show less
Step 3: Assess Operational Health
Check infrastructure and operational aspects:
- Data volume — estimate rows per table from code hints, migration data, or direct queries
- Backup status — is there a backup strategy? Automated? Tested?
- Connection pooling — is it configured? What tool (PgBouncer, built-in pool, ORM pool)?
- Replication — read replicas? Failover configured?
- Monitoring — any database monitoring in place?
Step 4: Analyze Query Patterns
Read through the application code to understand how the database is used:
- ORM queries — what patterns dominate? Any N+1 risks?
- Raw SQL — any complex queries? Stored procedures?
- Transaction patterns — how are transactions scoped? Any long-running transactions?
- Read/write ratio — is this read-heavy, write-heavy, or balanced?
