Coding & Dev Tools
Coding agent skills teach AI agents repeatable engineering workflows: reviewing pull requests, writing tests, refactoring safely, and enforcing house style. Install one SKILL.md and your agent applies the same checklist every time, whether you use Claude Code, Cursor, Codex, or another agent.
-
tachyon-beep Bundle Using Systems ThinkingUse when a problem keeps recurring despite fixes, when interventions produce side effects or backfire, or when you need to find high-leverage interventions in a complex system - routes to systems-thinking methodology (patterns, leverage points, archetypes, stocks-flows, causal loops, BOT graphs)
-
tachyon-beep Bundle Using Program ManagementUse when **managing the delivery of work** rather than building it — running a project or a program, not writing its code. Use when a team is busy but outcomes are not landing, when "when will it be done" has no defensible answer, when status is green every week until it is suddenly red, when dependencies surprise you, when a RAID log is a graveyard, or when several projects must be coordinated toward one outcome (a program). Lean/agile-leaning, honest about where program scale needs predictive structure. Pairs with `/axiom-planning` (turning one workstream into an implementation plan) and `/sdlc-engineering` (process maturity, requirements traceability, formal governance). Do not load for writing code, picking an architecture, or designing a single feature.
