orc-discover

orc-discover is a skill for Claude Code, Codex from qGolem/orc. It costs 17 tokens per session (554 once invoked), scanned A, original, MIT.

A codebase-discovery step for the Orc planning workflow. It explores an existing project and records relevant code patterns for a plan.

In plain words
What is it for?
It finds related features, naming conventions, API and route patterns, error handling, and testing examples, with references to the relevant files and lines.
Why use it?
It helps avoid planning changes without first understanding how the project is organized and how similar code is written.

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

orc-discover 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.

What it actually says

Orc Discover

Codebase exploration that runs forked (non-interactive).

Input

  • $ARGUMENTS — Plan slug

Template

See templates/STATE.md for output format.

Process

Step 0: Validate Slug

Tree the plans directory at depth 1 to see existing plan directories:

tree .claude/plans -L 1 -d

Compare the tree output against the provided $ARGUMENTS slug. If the slug matches a directory exactly, proceed with that directory. If it doesn't match exactly but a visible directory is clearly the right one (typo, case variation, truncation), use that directory instead. Use the matched directory path for all subsequent steps.

Step 1: Load Vision

Read .claude/plans/$ARGUMENTS/PROJECT.md

Extract search targets from vision.

Step 2: Pattern Discovery

Use Glob and Grep. Find 2-3 examples of each (emphasized: depth matters):

  • Similar existing functionality
  • File/test naming conventions
  • API/route patterns
  • Error handling patterns

Step 3: Convention Analysis

For discovered files, document with file:line references:

  • Code style (naming, organization)
  • Error handling approach
  • Testing patterns

Step 4: Integration Mapping

For each file to modify:

  • Current purpose
  • What will change
  • Dependencies (via rg "import.*filename")
  • Risk level (H/M/L)

Step 5: Write STATE.md

Write .claude/plans/$ARGUMENTS/STATE.md using template.

Include these required sections:

  • Current Phase — Track progress state
  • Decisions Made — Audit trail for architectural choices
  • Blockers — Surface impediments early

Constraint

Cannot use AskUserQuestion — forked context is non-interactive.

Completion Criteria

  • Found 2-3 examples of similar patterns
  • Documented all files to modify with risk levels
  • Identified integration points
  • Surfaced risks with mitigations
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

orc-discover is a skill published in the GitHub repository qGolem/orc (5 stars, last pushed 5mo ago), licensed MIT. It adds 17 tokens to every session and 554 once invoked, about $0.0001 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.
