Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00113 | $0.08711 |
| Opus 5.5 | $0.00045 | $0.03484 |
| Sonnet 5.5 | $0.00023 | $0.01742 |
| Haiku 4.5 | $0.00011 | $0.00871 |
Grade D, and why
crow-cascade-epic scanned grade D with 2 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 15d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

Crow Cascade Epic Skill
Purpose
Turns one epic into a dependency-gated cascade of Crow work sessions:
- Read the epic and its sub-tickets, and build the dependency DAG.
- Layer the DAG into waves (wave 1 = no dependencies; wave k+1 = everything whose dependencies sit in waves ≤ k).
- Start one Crow work session per ticket of the current wave — sequentially, through
/crow-workspace'ssetup.sh. - Seed every coder with the cascade contract: one PR scoped to its ticket,
Closes #N, a human reviewer requested, no self-approval, and the gate's label rule. - Arm a wave watcher that returns when every PR in the wave has merged, then launch the next wave.
This skill is an orchestrator on top of /crow-workspace. It never creates worktrees, sessions, or terminals itself: every ticket goes through .claude/skills/crow-workspace/setup.sh, and every naming, ticket pre-fetch, custom-instructions, and prompt rule in /crow-workspace still applies. Read that skill for anything this one says "per /crow-workspace".
It does not replace /crow-batch-workspace either — see Why sessions are created one at a time.
Important: Sandbox Bypass
All crow, gh, glab, and git worktree commands require dangerouslyDisableSandbox: true because they communicate via Unix socket, need network/TLS access, or write outside the sandbox-allowed directories. So does cascade.sh, which runs gh and crow internally.
Activation
This skill activates when:
- User invokes
/crow-cascade-epic <epic-url>(with any of the flags below) - User asks to "cascade", "run the waves of", or "work an epic wave by wave" in Crow
Input
/crow-cascade-epic <epic-url> [--gate human|auto] [--reviewer <login>] [--wave <n>] [--dry-run] [--explore] [--no-comment]
| Flag | Default | Meaning |
|---|---|---|
<epic-url> |
required | The epic issue that owns the sub-tickets — GitHub, GitLab, or Jira (see Limitations). |
--gate <human or auto> |
inferred (see Phase 2) | Which merge gate releases the next wave. |
--reviewer <login> |
dgershman |
The human who reviews every PR in the cascade. |
--wave <n> |
resume point | Start at wave n, treating waves < n as done (persisted as start_wave). |
--dry-run |
off | Plan only: print the wave map and stop. No sessions, comments, or watcher. |
--explore |
off | Create exploration sessions for one wave instead of work sessions (see Explore mode). |
--no-comment |
off | Don't post the cascade contract as a comment on each ticket. |
What ships with it
2 files 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.
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.

crow-cascade-epic is a skill published in the GitHub repository corveil/crow (18 stars, last pushed today), licensed Apache-2.0. It adds 113 tokens to every session and 8,711 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it D with 2 findings (hidden instructions, reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-01.
