gather-context

Use at the start of creating context, to understand the problem the user is solving and take stock of what they already have. The user may arrive with an existing skill or plugin, code, a written prompt or transcript, or nothing but a pointer ("go look at my PRs"). Gathers what exists and fills the gaps - by asking or by hunting - until there is enough to plan a composition.

Quality

Content

85%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 well-structured, lean process skill: clear sequenced workflow with an explicit confirmation checkpoint and stop condition, concrete probes and file paths, and an appropriately placed one-level-deep reference. The only minor room for improvement is trimming a few coaching sentences and tightening the abstract guidance around problem understanding.

DimensionReasoningScore

Conciseness

Mostly lean with no explanations of concepts Claude already knows, but a few dispensable coaching lines ('Users arrive in different states, meet them where they are', 'The material you need may already be the thing they are trying to create') could be trimmed. Not 5 because these framing sentences don't earn their tokens.

4 / 5

Actionability

Gives concrete, executable guidance: a specific probe script ('you have given me the what; I still need when the agent should reach for this...'), concrete paths (`.tessl/memory/preferences/` with `plugins.md`, `agents.md`, `source-control-and-ci.md`), and clear ask/hunt/infer decision rules. Not 5 because some direction stays abstract ('Get the problem clear in a sentence or two', 'make sure you understand the problem').

4 / 5

Workflow Clarity

Clear four-step sequence (understand -> take stock -> fill gaps -> confirm) with an explicit validation checkpoint and feedback loop ('Before handing to plan-composition, make sure you understand... If not, keep gathering. Do not jump to building') plus a separate 'When to stop' section. This validate-and-retry loop exceeds the anchor-4 example, and no destructive/batch cap applies.

5 / 5

Progressive Disclosure

The body is short and well-sectioned, and the single reference (references/hunting-artifacts.md, verified to exist) is one level deep, clearly signaled at its point of use in 'Fill the gaps', and appropriately splits the detailed hunting instructions out of the main flow.

Description

67%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.

The description communicates a clear purpose and an explicit use point in the composition workflow, with concrete input types enumerated. Its main weakness is trigger quality: it is framed around workflow position rather than natural user-need phrases, which limits when-based discoverability.

Suggestions

Add natural user-need trigger phrases, e.g. 'Use when the user asks to create, fix, or improve a skill or plugin and arrives with partial material (a messy skill, code, a prompt, or just a pointer to their PRs)'.

Make the 'when' concrete instead of workflow-internal: replace 'at the start of creating context' with situations a user would describe, such as 'before planning or writing a skill'.

DimensionReasoningScore

Specificity

Lists several specific actions ('take stock of what they already have', 'Gathers what exists and fills the gaps - by asking or by hunting') plus concrete input types ('an existing skill or plugin, code, a written prompt or transcript, or nothing but a pointer'). Falls short of 5 because phrases like 'understand the problem' remain abstract and coverage is not fully concrete.

4 / 5

Completeness

Has a clear 'what' (gather what exists, take stock, fill gaps 'until there is enough to plan a composition') and an explicit 'when' ('Use at the start of creating context'), so the missing-trigger cap does not apply. Not 5 because the 'when' is abstract and lacks concrete user trigger phrases.

4 / 5

Trigger Term Quality

Relevant keywords appear (skill, plugin, code, prompt, transcript, PRs) including one natural user quote ('go look at my PRs'), but the trigger is framed as workflow position ('Use at the start of creating context') rather than phrases a user would naturally say when they need this skill ('my skill is a mess', 'help me improve my skill').

3 / 5

Distinctiveness Conflict Risk

Occupies a niche (skill/plugin composition workflow) with distinguishing terms like 'plan a composition' and 'existing skill or plugin'. Minor overlap risk with generic context-gathering or discovery skills due to broad phrases like 'understand the problem the user is solving'.
