Trailmark Structural Analysis

Runs trailmark analyze with all four pre-analysis passes.

When to Use

Vivisect Phase 1 needs full structural data (hotspots, taint, blast radius, privilege boundaries)
Detailed pre-analysis passes for a specific target scope
Generating complexity and taint data for audit prioritization

When NOT to Use

Quick overview only (use trailmark-summary instead)
Ad-hoc code graph queries (use the main trailmark skill directly)
Target is a single small file where structural analysis adds no value

Rationalizations to Reject

Rationalization	Why It's Wrong	Required Action
"Summary analysis is enough"	Summary skips taint, blast radius, and privilege boundary data	Run full structural analysis when detailed data is needed
"One pass is sufficient"	Passes cross-reference each other — taint without blast radius misses critical nodes	Run all four passes
"Tool isn't installed, I'll analyze manually"	Manual analysis misses what tooling catches	Report "trailmark is not installed" and return
"Empty pass output means the pass failed"	Some passes produce no data for some codebases (e.g., no privilege boundaries)	Return full output regardless

Usage

The target directory is passed via the args parameter.

Execution

Step 1: Check that trailmark is available.

trailmark analyze --help 2>/dev/null || \
  uv run trailmark analyze --help 2>/dev/null

If neither command works, report "trailmark is not installed" and return. Do NOT run pip install, uv pip install, git clone, or any install command. The user must install trailmark themselves.

Step 2: Detect the primary language.

find {args} -type f \( -name '*.rs' -o -name '*.py' \
  -o -name '*.go' -o -name '*.js' -o -name '*.jsx' \
  -o -name '*.ts' -o -name '*.tsx' -o -name '*.sol' \
  -o -name '*.c' -o -name '*.h' -o -name '*.cpp' \
  -o -name '*.hpp' -o -name '*.hh' -o -name '*.cc' \
  -o -name '*.cxx' -o -name '*.hxx' \
  -o -name '*.rb' -o -name '*.php' -o -name '*.cs' \
  -o -name '*.java' -o -name '*.hs' -o -name '*.erl' \
  -o -name '*.cairo' -o -name '*.circom' \) 2>/dev/null | \
  sed 's/.*\.//' | sort | uniq -c | sort -rn | head -5

Map the most common extension to a language flag:

.rs -> --language rust
.py -> (no flag, Python is default)
.go -> --language go
.js/.jsx -> --language javascript
.ts/.tsx -> --language typescript
.sol -> --language solidity
.c/.h -> --language c
.cpp/.hpp/.hh/.cc/.cxx/.hxx -> --language cpp
.rb -> --language ruby
.php -> --language php
.cs -> --language c_sharp
.java -> --language java
.hs -> --language haskell
.erl -> --language erlang
.cairo -> --language cairo
.circom -> --language circom

Step 3: Run the full structural analysis.

trailmark analyze \
  --passes blast_radius,taint,privilege_boundary,complexity \
  {language_flag} {args} 2>&1 || \
uv run trailmark analyze \
  --passes blast_radius,taint,privilege_boundary,complexity \
  {language_flag} {args} 2>&1

Step 4: Verify the output.

The output should include:

Hotspot scores (complexity data)
Tainted node list (taint propagation data)
Blast radius data
Privilege boundary information
