titan-recon

A codebase analysis workflow that maps how parts of a software project depend on one another. It also groups code into logical areas and identifies places likely to need cleanup.

In plain words
What is it for?
Use it to find tightly connected or risky areas, divide cleanup into manageable batches, and create a ranked work queue.
Why use it?
It gives developers a structured view of a large or unfamiliar codebase before they decide what to change.

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

titan-recon 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 2d 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.

Titan RECON — Codebase Reconnaissance

You are running the RECON phase of the Titan Paradigm on the target at $ARGUMENTS (default: .).

Your goal: map the dependency graph, identify structural hotspots, name logical domains, produce a global architecture document, propose work batches, and initialize the session state. Everything you produce feeds downstream phases (GAUNTLET, SYNC, GATE) via artifacts in .codegraph/titan/.

Context budget: Every codegraph command MUST use --json to keep output compact. Never dump raw CLI tables into context — parse JSON and extract only what you need.


Step 0 — Pre-flight: worktree and sync

  1. Check for worktree isolation:

    git rev-parse --show-toplevel && git worktree list
    

    If you are NOT in a worktree, stop: "Run /worktree first. Titan phases write artifacts that should not interfere with other work."

  2. Sync with main:

    git fetch origin main && git merge origin/main --no-edit
    

    If there are merge conflicts, stop and ask the user to resolve them.

  3. Record the main anchor SHA:

    git rev-parse origin/main
    

    Store this as mainSHA in titan-state.json. All downstream phases use this to detect codebase drift — if main advances between phases, the drift detection mechanism (Step 0.5 in each phase) compares against this anchor to determine what's stale and what needs reassessment.


Step 1 — Build the graph

codegraph build $ARGUMENTS

Record: file count, node count, edge count, engine.


Step 2 — Generate embeddings (for DRY detection in GAUNTLET)

codegraph embed -m minilm

This enables codegraph search for duplicate code detection in downstream phases. If it fails (e.g., missing model), note it and continue — DRY checks will be grep-only.

Verify, don't assume. .codegraph/ is gitignored — graph.db (and its embeddings) is local filesystem state, per worktree. It is never carried over by git merge, a branch switch, or a snapshot restore. Before setting embeddingsAvailable in titan-state.json, smoke-test the current worktree's DB directly:

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.

titan-recon is a skill published in the GitHub repository optave/ops-codegraph-tool (92 stars, last pushed yesterday), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 3,081 tokens. 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.
