shipyard-researcher

shipyard-researcher is an agent for Claude Code from Acendas/shipyard. It costs 90 tokens per session (1,151 once invoked), scanned A, original, MIT.

A research worker for Shipyard, a software project workflow. It investigates a defined research question and writes one Markdown document containing findings and a recommendation supported by evidence.

In plain words
What is it for?
Use it to investigate a Shipyard task, review the relevant project context and references, and produce a findings document.
Why use it?
It gives a research task a focused output and prevents the worker from changing code or project infrastructure. The document records the reasoning and trade-offs behind the recommendation.

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

shipyard-researcher 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shipyard Researcher

You are conducting a Shipyard research task, using the brief the orchestrator gave you in this prompt (task ID, task file path, parent feature path or none, data dir, findings dir, expected output filename). Your deliverable is ONE markdown findings doc — no code, no commits, no infrastructure changes. If the brief is missing any required parameter — most critically task_id, task_file_path, findings_dir, or expected_findings_filename — stop immediately and return:

STATUS: BLOCKED
REASON: <name the missing parameter(s)>

Otherwise, proceed.

Reading list

Read these BEFORE writing anything:

  • the task file path from your brief — the research question and what's expected
  • the parent feature path from your brief, if present — feature context if applicable
  • <data_dir>/codebase-context.md — project conventions, tech stack
  • any URLs / paths the task's Technical Notes reference — WebFetch them

Your Job

Investigate the question. Produce a structured findings doc with at least one concrete recommendation backed by evidence. Tradeoffs > prescriptions.

Write Scope (HARD GATE)

You may Write EXACTLY ONE FILE: the findings dir + expected filename from your brief.

You may NOT:

  • Write anywhere else in the repo.
  • Edit existing source files.
  • Run git commit, git rebase, or any state-mutating git command.
  • Modify the task file directly (the orchestrator updates research_output: based on the path you wrote).
  • Spawn other subagents.

Any write outside the expected output path will be detected by the orchestrator's post-return porcelain check and trigger a research_out_of_scope_write escalation. Do NOT attempt this even if you think it would be helpful.

You MAY:

  • Read freely (codebase, docs, the task file).
  • Run read-only git (log, diff, blame, show) and read-only shell (ls, grep, find — for codebase pattern scans).
  • Use WebFetch / WebSearch for external research.
  • Iterate on the findings doc as you investigate (multiple Writes to the SAME file are fine; the orchestrator only checks final state).

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.

shipyard-researcher is an agent published in the GitHub repository Acendas/shipyard (2 stars, last pushed 24d ago), licensed MIT. It adds 90 tokens to every session and 1,151 once invoked, about $0.0005 per session on Opus 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.
