What it does
Ad Deepen is an agent skill from alexandremendoncaalvaro/CorridorKey-Runtime. Surface deepening opportunities in the codebase using the Ousterhout/Feathers vocabulary from WORKFLOW §8 (Module / Interface / Depth / Seam / Adapter / Leverage / Locality). Three-phase process — explore organically, present numbered candidates with deletion-test framing, grilling loop on the chosen candidate. Pairs with ad-drift (audit detects drift; deepen proposes refactors). Triggers on "deepen", "refactor for depth", "shallow module", "deletion test", "two-adapters rule", "interface is the test surface"…
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in Development, covering Refactoring, Architecture decision records and Requirements gathering. The repository describes itself as: Native AI keying runtime and OFX plugin for DaVinci Resolve, built in collaboration with Corridor Digital.
When your agent uses it
- Refactor for depth
- Two-adapters rule
- Interface is the test surface
Example prompts
- “deepen”
- “refactor for depth”
- “shallow module”
- “/ad-deepen”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Read CONTEXT.md if it exists. Anchor domain vocabulary; deepening proposals must use Customer, Order, Triage role — not Service, Handler…
- Read ARCHITECTURE.md if it exists. Read accepted ADRs in doc/adr/ covering the surface you are about to walk.
- Walk the codebase noting friction
What it can do on your machine
Read from SKILL.md and the folder at commit e632fa5. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ad Deepen loads about 2k tokens when it runs. Until then it costs about 165 tokens; SKILL.md has 822 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 822 words (~2,031 tokens).
“Implements ADR-0020 (doc/adr/0020-deep-modules-vocabulary.md) — operational counterpart to the WORKFLOW §8 architectural vocabulary. Surfaces deepening opportunities and walks the user through them. Process scaffold; no primary file output.”
