tsa-temporal

tsa-temporal is a skill for Claude Code, Codex from aimasteracc/tree-sitter-analyzer. It costs 170 tokens per session (1,423 once invoked), scanned A, original, MIT.

A code-review aid that uses recent Git history to identify symbols—such as functions—that change frequently. These frequently changed areas are called hot zones.

In plain words
What is it for?
Finding frequently modified callers and callees, checking whether a commit touches hot zones, and viewing recent file-level churn.
Why use it?
It adds change history to code-impact checks, helping focus review on parts of the codebase where edits may carry more risk.

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

tsa-temporal 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 5d 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.

tsa-temporal — Hot zones via git history

Per-symbol modification frequency persisted in ast_symbol_activation. Computed from git log --follow -p -U0 hunk attribution at index time. Symbols with mod_count_30d >= 5 auto-trigger CAUTION in edit action=impact.

When to use

Goal How
Hot-zone caller fanout nav action=callers function_name="X" include_activation=true
Hot-zone callee fanout nav action=callees function_name="X" include_activation=true
"Is this commit touching hot zones?" edit action=impact — read risk_factors
Single-file recent churn health action=file — read git_hotspot dim

Don't use when:

  • The question is static (e.g. "who calls X") — use tsa-graph skill
  • File is brand new (no git history) — temporal data will be all-zero

Procedure

Pre-refactor hot-zone scan

For each symbol you're about to refactor:

nav action=callers function_name="X" include_activation=true limit=50

Returns enriched entries:

callers: [
  {
    name: ...,
    file: ...,
    line: ...,
    callee_resolution: ...,
    activation: {
      mod_count_30d: <int>,
      last_modified_at: <unix ts>
    }
  }, ...
]

Filter mod_count_30d >= 5 to find the callers that have been modified recently — those are the high-risk integration points for your refactor.

Change-impact gate (catches hot zones automatically)

edit action=impact already includes hot-zone detection. Look for this in the risk_factors:

risk_factors: [
  {
    factor: hot_zone | activation,
    reason: "hot zone: file_path:symbol modified 12× in 30d, request extra review",
    severity: caution
  }
]

The verdict bumps to CAUTION when ≥1 changed-file symbol has mod_count_30d >= 5.

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.
