Included Skills22

agent-guardrailsskills/agent-guardrails/SKILL.md

Always-on safety guardrails — no privileged mutations without approval, no sensitive data off-box. The backstop for when permission gating is relaxed.

anti-spinningskills/anti-spinning/SKILL.md

Always-on loop-breaker — stop repeating a failed approach, and honor a cancel/stop/undo request immediately. The 3-strike rule.

complete-the-conceptskills/complete-the-concept/SKILL.md

Always-on completion discipline — a change is ONE conceptual action, finished when the concept is, not when the first commit merges. Follow the thread to every carrier and consumer.

context-checkpointingskills/context-checkpointing/SKILL.md

Always-on checkpoint discipline — the single overwritten CHECKPOINT.md carrying the validation loop, ordered next actions, and in-flight handles; written before a risky step and when the context grows heavy, read back after compaction or a restart.

context-efficiencyskills/context-efficiency/SKILL.md

Always-on context-budget discipline — shield the context with subagents and files, peek instead of streaming, and phase work so artifacts survive compression.

critical-stanceskills/critical-stance/SKILL.md

Use when evaluating a technical claim, reviewing work or peer-agent output, researching, or being asked to agree — enforces adversarial verification over deference. Not a yes-man.

design-by-contractskills/design-by-contract/SKILL.md

Use when writing rules, defining agent roles, or authoring multi-step operational instructions — anchor every instruction to verifiable execution states.

facts-are-fieldsskills/facts-are-fields/SKILL.md

Always-on structural discipline — where a record already holds a fact, it belongs in a field a writer can REFUSE, never in a filename, a heading, a name segment, or a prose substring recovered by pattern. Both shapes fail by returning a plausible zero. Scoped to bypassing an existing record; where none exists, prefer generating the derived carrier over guarding two hand-written ones.

git-proficiencyskills/git-proficiency/SKILL.md

Use when performing git operations — repository health guardrails (big-file check, no destructive deletes), surgical recovery, and the maintained cheatsheet.

markdown-proficiencyskills/markdown-proficiency/SKILL.md

Use when producing documentation, reports, or structured artifacts — advanced Markdown and GitHub-flavored features (collapsible sections, alerts, diff blocks, semantic footnotes, Mermaid), with the maintained cheatsheet.

pair-programmingskills/pair-programming/SKILL.md

Use when working interactively with the human on code — driver/navigator roles, ping-pong test-driven development, adversarial review, and hold-on-submit.

plan-act-reflectskills/plan-act-reflect/SKILL.md

Always-on phase discipline — an approved plan before acting, reflection on failure, and verification against the original objective before claiming done.

project-memoryskills/project-memory/SKILL.md

Use for any long-running or multi-session workstream — the four-artifact projects/<name>/ discipline that lets work survive compaction and restarts.

qlty-proficiencyskills/qlty-proficiency/SKILL.md

Use when formatting, linting, or assessing code quality — operational patterns for the qlty command-line tool, with the maintained cheatsheet.

refactoring-safetyskills/refactoring-safety/SKILL.md

Use when refactoring, restructuring, or resolving a fault — behavior-preserving, green build and tests, class-of-problem fixes, uniform design over hacks.

scratch-policyskills/scratch-policy/SKILL.md

Use when a task needs working files or large intermediate data — scratch artifacts are compression insurance; keep them current, self-evident, and out of the repo.

semantic-consentskills/semantic-consent/SKILL.md

Always-on consent boundary — the human owns intent, you own syntax; on ambiguity, split by reversibility — decide and disclose what you can undo, ask before what you cannot.

spec-driven-developmentskills/spec-driven-development/SKILL.md

Use when creating, reviewing, or auditing an implementation plan — the mandatory five-section plan structure (numbered I through V, from Summary & Goals to the Verification Plan), the TinySpec loop for small work, and the auditor gate.

terse-communicationskills/terse-communication/SKILL.md

Always-on output discipline — strict token economy. No filler, no process play-by-play, no wrap-up summaries. Applies to every response.

test-driven-developmentskills/test-driven-development/SKILL.md

Use when building or changing behaviour that can be tested — red/green/refactor discipline, test-first contracts, and the ping-pong variant for pairing.

think-around-problemskills/think-around-problem/SKILL.md

Always-on anti-satisficing — question everything (the human, docs, comments, research), explore alternatives in proportion to the stakes, never take the first workable answer.

validation-loopskills/validation-loop/SKILL.md

Always-on verification discipline — a written, executable validation loop that outlives the plan; run it before claiming anything works.
