Use when creating a new change with all SDD artifacts — proposal, delta specs, design, and tasks. Triggers: "propose a change", "create a change for X", "I want to implement feature Y", "start a new change", "let's build X".
Skill Claude CodeCodex
Use when merging delta specs from a change into the main baseline specs. Triggers: "sync specs", "merge delta specs", "update main specs", "apply the spec changes", "sync the change".
Skill Claude CodeCodex
Use when translating or migrating existing specs from another tool or format (Spec Kit, Kiro, ADRs, Jira, Confluence, Word docs, or custom markdown requirements) into SDD spec format. Also use when the user says "convert these specs", "migrate to SDD", "translate from X to SDD", or "import specs".
Skill Claude CodeCodex
Use when verifying that an implementation matches a change's SDD artifacts. Triggers: "verify", "check implementation", "did I implement everything", "verify the change", "is implementation complete", "check conformance".
Skill Claude CodeCodex
Use when the user wants any spec-driven development action — exploring before speccing, deriving specs from code or translating specs from another system, proposing a change, applying or implementing, verifying, syncing delta specs, or archiving. Triggers: 'spec this out', 'create a change', 'apply tasks', 'verify…
Skill Claude CodeCodex
Use when writing or reviewing code that handles external input, manages access, touches data or crypto, or changes dependencies. Triggers: endpoints, auth/authz, DB/ORM, file handling, secrets, "is this secure?", "security review". NOT for formatting, pure UI, or explaining code.
Skill Claude CodeCodex
Use when the user asks for a deep, exhaustive, multi-pass, or variance-reducing repository-wide or scoped-path security scan. Run repeated independent discovery passes over one resolved scope with worker-specific threat models, semantically merge candidates, synthesize one canonical validation threat model, then run…
Skill Claude CodeCodex
Use when the user explicitly asks to fix and verify a validated or plausible security finding. Do not use as the primary trigger for full PR, commit, branch, patch, or repository scans.
Skill Claude CodeCodex
Use when the user asks for a security scan or review of a repository, a scoped path (package, folder, or submodule), or a Git-backed change set (pull request, commit, branch diff, or working-tree patch). Point it at the target; it runs the full threat-model, discovery, validation, and attack-path pipeline and writes a…
Skill Claude CodeCodex
Use when the user supplies existing security findings or vulnerability reports — SARIF results, CVE/GHSA or advisory text, scanner tickets, bug bounty reports, or finding artifacts — and wants static repo-impact triage. Do not use for discovery, duplicate-bug triage, validation, or fixes.
Skill Claude CodeCodex
Use when writing or reviewing Bash scripts and shell snippets, especially for shebang selection, quoting, parameter expansion ("${VAR}" style), test expressions ([ ] vs [[ ]]), ShellCheck-guided fixes, and portability decisions across POSIX sh, Bash, and zsh compatibility targets.
Skill Claude CodeCodex
Use when the user needs to see something to answer the current question — a sketch of logic, runtime flow, UI structure, or file layout; a Mermaid diagram; a chart of the data at hand; a mockup, wireframe, or side-by-side comparison during a design discussion (visual brainstorming). Triggers: "show me", "sketch this"…
Skill Claude CodeCodex
Use to cut slop out of working code: duplication, dead code, needless indirection, comment noise, defensive padding. Point it at the current changes, a file, a directory, or the whole repo. Triggers: 'simplify this', 'clean this up', 'de-slop this code', 'strip the cruft', 'tighten this diff', 'this code is bloated'…
Skill Claude CodeCodex
Use when writing, debugging, or explaining Strudel live-coding music patterns — mini-notation syntax, pattern functions (fast/slow/every/off/stack), synth/sample selection, audio effects, scale/chord/voicing API, or EDM production recipes. Triggers: "write a Strudel pattern", "how do I make a bassline in Strudel"…
Skill Claude CodeCodex
Use when dispatching development work to one or more subagents and deciding how to shape each dispatch. Triggers: "use subagents", "orchestrate subagents", "delegate to a cheaper/stronger model", "big:little" / "little:big", "verifier / adversary / explorer / oracle subagent", "run this with subagents", "get an…
Skill Claude CodeCodex
Use when distilling the through-line gist of one or more sources — the spine, argument, tension, or recurring frame running through a set of documents, notes, research, or transcripts, OR across the ideas within a single rich piece — into a few concise paragraphs. Triggers: "synthesize", "what's the…
Skill Claude CodeCodex
Use when the user wants to be taught a subject, not just answered — "teach me X", "help me learn X", "help me understand X", "help me grok X", "explain how X works", "quiz me on X", "I keep bouncing off X" — where X can be anything: a historical period, a statistical method, music theory, a poem, a legal concept, a…
Skill Claude CodeCodex
Use when writing or reviewing tests in any language, or diagnosing a suite that is slow, brittle, or hard to read. Triggers: "write tests", "how should I test this", "what kind of test", "test is flaky/fragile", "should I mock this", "test is hard to read". Python-specific practices (mocking, pytest, async) are…
Skill Claude CodeCodex
Use when an agent in one harness must create, observe, or steer one or more agents in another harness through a tmux session the user can watch. Triggers: "use an agent in another harness", "bridge to ", "run in tmux", "use a different harness", "check on the external agent". Not for subagents or delegation inside the…
Skill Claude CodeCodex
Use when the user asks for formal verification or formal methods: writing or checking a design model (TLA+, Alloy, P, Quint), proving code against contracts (Dafny, Verus, SPARK, Frama-C, Lean, Rocq), model checking, invariants, liveness, vacuous passes, or counterexamples; deciding whether a design or requirement…
Skill Claude CodeCodex
Use when writing, rewriting, or auditing Python docstrings that a documentation site is generated from, or when docstrings are long, narrate the code, or leave a reader of the generated reference unable to find their way. Triggers - "audit the docstrings", "docstring slop", "docstrings as documentation", "the API…
