survey-code

survey-code is a skill for Claude Code from nirecom/agents. It costs 20 tokens per session (1,174 once invoked), scanned A, original, MIT.

A codebase investigation workflow that examines existing files, patterns, and constraints before planning a change.

In plain words
What is it for?
Use it to explore a repository before writing an implementation plan and identify the files and conventions that matter.
Why use it?
It reduces the risk of planning work that conflicts with the project’s current structure or misses relevant code.

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

survey-code 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 today.

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.

Investigate the codebase related to the given task.

Procedure

SVC-0 — Resolve <PLANS_DIR>

Before any tool call below that references <PLANS_DIR>, run bash "$AGENTS_MAIN_ROOT/bin/workflow-plans-dir" exactly once as one bare command — never assigned to a variable and echoed back.

Read the printed absolute path from its stdout and substitute it for every <PLANS_DIR> placeholder in the remainder of this SKILL.md. Subagent prompts must receive the resolved absolute path as a literal string (subagents cannot expand $VAR). Reuse across all subsequent in-skill steps in this invocation — do not re-resolve.

When invoked as a parallel Agent subagent by workflow-init, the orchestrator passes artifact_path and context_path as resolved absolute strings — use those instead of running SVC-0.

Canonical documentation: skills/_shared/resolve-plans-dir.md.

SVC-1. Claim extraction (run before reading any code): Input precedence (read whichever exists first): (a) the path printed by node "$AGENTS_MAIN_ROOT/bin/plan-artifact-path" --stage intent (it follows a resumed session's upstream) — preferred (post-clarify-intent calls) (b) <PLANS_DIR>/<session-id>-context.md — fallback (pre-clarify-intent calls from workflow-init; use "User initial prompt" and "Issue body" sections) If neither exists: proceed to SVC-2 with an empty claim list. Extract up to 5 behavioral/factual claims from Background/Motivation and Scope. Target: "X is blocked", "X does Y", "X is broken", "X cannot Z". Exclude aesthetic claims and pure preferences. Works with Japanese and English content.

SVC-2. Identify candidate files and areas using Glob and Grep. SVC-3. Read relevant source files, configs, tests, and docs. SVC-4. For each claim extracted in SVC-1, verify it against the current codebase:

  • verdict: holds — evidence in code confirms the claim
  • verdict: contradicted — evidence in code contradicts the claim
  • verdict: indeterminate — insufficient evidence to confirm or deny SVC-5. Summarize: existing patterns, architectural constraints, relevant files (with line numbers), and anything that affects implementation. SVC-6. Write findings to <PLANS_DIR>/<session-id>-survey-code.md. The file must include a ## Verified Claims section:
## Verified Claims
- claim: <text from intent.md>
  verdict: holds | contradicted | indeterminate
  evidence: <file:line or "no matching code found">

If no claims were extracted in SVC-1, write the section with the note "No verifiable behavioral/factual claims found in intent.md or context.md."

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.

survey-code is a skill published in the GitHub repository nirecom/agents (3 stars, last pushed today), licensed MIT. It adds 20 tokens to every session and 1,174 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
