Claude Octopus is an orchestration project that sends research, design, and coding tasks to Claude Code and other AI model providers so their results can be compared. Developers use it for multi-model work, disagreement detection, reviews, persistent context, and an optional workflow that moves from discovery through delivery. The catalogue entries are its commands, skills, agents, instructions, hooks, plugins, and settings.
Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.02885 |
| Opus 5 | $0.00009 | $0.01443 |
| Sonnet 5 | $0.00004 | $0.00577 |
| Haiku 4.5 | $0.00002 | $0.00288 |
Grade A, and why
skill-staged-review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 338 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Two-Stage Review Pipeline
Separates spec compliance (did you build the right thing?) from code quality (did you build it right?). Stage 1 must pass before Stage 2 runs.
Stage 1: Spec Compliance
Validates the implementation against the intent contract.
Step 1: Load Intent Contract
PLAN_STORAGE="${CLAUDE_PLUGIN_ROOT:-${HOME}/.claude-octopus/plugin}/scripts/plan-storage.sh"
OCTO_PLAN_DIR="$("$PLAN_STORAGE" current "$PWD" 2>/dev/null || true)"
INTENT_FILE="${OCTO_PLAN_DIR:+${OCTO_PLAN_DIR}/session-intent.md}"
if [[ -f "$INTENT_FILE" ]]; then
echo "Intent contract found: $INTENT_FILE"
cat "$INTENT_FILE"
else
echo "WARNING: No current resolved intent contract found for this workspace"
echo "Skipping Stage 1 — proceeding to Stage 2 (code quality) only."
fi
If no intent contract exists: Warn the user and skip to Stage 2. Do NOT fabricate success criteria — the contract must exist from a prior workflow.
Step 2: Validate Success Criteria
For each success criterion in the intent contract:
- Read the criterion from the
## Success Criteriasection - Find evidence in the codebase that the criterion is met
- Mark status:
[PASS]— Evidence confirms criterion is met[FAIL]— Evidence shows criterion is NOT met[PARTIAL]— Partially met, gaps identified
Present results:
## Stage 1: Spec Compliance
### Success Criteria Check
#### Good Enough Criteria
- [PASS] Criterion 1: <how it was met>
- [FAIL] Criterion 2: <why not met, what's missing>
#### Exceptional Criteria
- [PARTIAL] Criterion 1: <what's done, what's remaining>
Step 3: Validate Boundaries
For each boundary in the intent contract:
- Read the boundary from the
## Boundariessection - Check for violations in the implementation
- Mark status:
[RESPECTED]— No violations found[VIOLATED]— Implementation crosses the boundary
### Boundary Check
- [RESPECTED] Boundary 1: <confirmation>
- [VIOLATED] Boundary 2: <what violated it>
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.

skill-staged-review is a skill published in the GitHub repository nyldn/claude-octopus (4,062 stars, last pushed today), licensed MIT. It adds 18 tokens to every session and 2,885 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 2026-08-30.
Other skills, from other repositories
drain-labeled-backlog
This skill should be used when draining a labeled issue backlog (deferred-scope-out, code-review, type/security) in one cleanup PR. Groups by code area and delegates to /soleur:one-shot.
drain-prs
This skill should be used when draining open remote GitHub PRs: triage every open pull request into mergeable tiers, confirm scope with the operator, then fix and merge the green ones. The PR-counterpart to drain-labeled-backlog.
agent-native-reviewer
Use this agent when reviewing code to ensure features are agent-native -- any action a user can take, an agent can also take, and anything a user can see, an agent can see. Enforces agent-user parity in capability and context.
architecture-strategist
Use this agent when you need to analyze code changes from an architectural perspective, evaluate system design decisions, or ensure modifications align with established architectural patterns. Use ddd-architect for Domain-Driven Design modeling; use this agent for general architectural compliance review.
kieran-rails-reviewer
Use this agent when you need to review Rails code changes with an extremely high quality bar. Applies Kieran's strict Rails conventions and taste preferences. Use dhh-rails-reviewer for opinionated architectural critique; use this agent for strict convention and quality checks.
pattern-recognition-specialist
Use this agent when you need to analyze code for design patterns, anti-patterns, naming conventions, and code duplication. This agent excels at identifying architectural patterns, detecting code smells, and ensuring consistency across the codebase.
