create-context

Use when someone wants to turn a problem, a messy or sprawling skill, or some existing work into well-shaped reusable context for their agent. Triggers include "help me make a skill for X", "my skill is a mess, sort it out", "I want to get more out of Tessl with this skill", or "package this so my team can use it". Runs the arc - understand the problem, gather the artifacts, plan the right composition, build it - then points to eval as a separate next step.

Content

86%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A lean, well-structured orchestrator skill: a clear four-phase arc with per-phase delegation to named sibling skills, real CLI commands, sensible principles, and an explicit stop condition. The main gaps are high-level directives in the gather/plan phases and no built-in verification loop, since correctness checking is pushed entirely to the separate eval flow.

Suggestions

Add one concrete example of 'enough material' at the end of phase 1 (e.g., what a gathered inventory looks like: skill files, code pointers, transcripts) so 'Make sure you have enough before moving on' is checkable rather than judgment-only.

Show the actual scaffolding invocation in phase 3 (e.g., `tessl plugin new <name>` with its expected output layout) so the build step is copy-paste ready instead of delegating the syntax entirely to build-composition and `tessl --help`.

Add a short error-recovery note for the arc itself — what to do when gathering still leaves gaps after hunting, or when the user rejects the plan — so the workflow has an explicit feedback loop rather than only forward gates.

DimensionReasoningScore

Conciseness

The ~30-line body is lean: every section carries task-specific instruction (phase delegation, CLI commands, principles, a stop condition) with no padding and no explanation of concepts Claude already knows. The eval point appears in both the intro and its own section, but the intro explicitly cross-references it ("see the end"), so it reads as deliberate signposting rather than waste.

5 / 5

Actionability

Concrete guidance is present — named sub-skills per phase, real commands ("tessl skill new", "tessl plugin new", "Inspect tessl --help"), and the path convention "skills/<name>/SKILL.md" — but several directives stay high-level ("Make sure you have enough before moving on", "Produce a short plan and confirm it", "add the planned hook or MCP fields and companion files") without the specific steps or examples needed to execute them directly. Mostly executable with minor gaps, not the copy-paste-ready 5.

4 / 5

Workflow Clarity

The four phases are numbered and sequenced, each with a named skill and purpose, gates exist ("Make sure you have enough before moving on", "confirm it", user agreement before changing content), and a "When to stop" section defines termination. It falls short of 5 because there is no explicit error-recovery or output-verification loop — verifying the built composition is deferred to the downstream eval flow rather than checked here.

4 / 5

Progressive Disclosure

Under 50 lines with well-organized sections and no inlined content that belongs in separate files; the only references are one-level-deep, clearly signaled pointers to sibling skills (gather-context, plan-composition, build-composition, publish-plugin, tessl/skill-optimizer) and no bundle files exist to restructure. Per the simple-skill guideline, this scores 5.

Description

96%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

A strong description that explicitly answers both what and when, in third-person voice, with natural quoted trigger phrases and a concrete summary of the skill's arc. Its only weakness is that one trigger ("help me make a skill for X") is not Tessl-specific, creating minor conflict risk with generic skill-creation skills.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions covering the full arc — "understand the problem, gather the artifacts, plan the right composition, build it - then points to eval as a separate next step" — with no meaningful gaps in coverage. It is not the 4 anchor because the action list is comprehensive rather than having minor gaps.

5 / 5

Completeness

Both questions are answered explicitly: what it does ("turn a problem, a messy or sprawling skill, or some existing work into well-shaped reusable context"; "Runs the arc") and when to use it ("Use when someone wants to..." plus concrete trigger phrases). This matches the 5 anchor exactly.

5 / 5

Trigger Term Quality

Four natural, quotable user phrases are provided: "help me make a skill for X", "my skill is a mess, sort it out", "I want to get more out of Tessl with this skill", and "package this so my team can use it", covering the make/fix/improve/package variations users would actually say. File extensions don't apply to this domain, and no common phrasing is missing.

5 / 5

Distinctiveness Conflict Risk

The Tessl-specific framing ("get more out of Tessl", skill/plugin composition) gives it a clear niche, but the trigger "help me make a skill for X" is generic enough to overlap with any general skill-authoring skill. Minor overlap risk with closely related skills places it at 4 rather than the minimal-conflict 5.
