What this skill tells your AI
The instructions your AI receives, as published by agentsope/skillalchemy in skills/LEAP/SKILL.md and read by ahel’s review.
LEAP does not choose the request type or interact with the user. SkillAlchemy selects the branch and handles each user checkpoint. LEAP runs the selected pipeline and returns the result.
Branch Routing
| Command | Branch | Pipeline |
|---|---|---|
distill / distillation | Branch A | Distillation pipeline — extract the target OS from raw data and compile it into a persona/tool skill |
fuse / fusion | Branch B | Fusion pipeline — method.skill (skeleton) × subject.skill(s) (flesh) → output.skill |
Invocation Modes
| Mode | Trigger | Behavior |
|---|---|---|
| Full run | No special keyword | Run the full pipeline and output a skill package |
| Plan only | stop after Stage 3 or stop_after_stage: 3 | Run Branch A Stages 1-3 only; stop after writing research_plan.json |
| Resume | continue from Stage 4 or resume_from_stage: 4 | Skip Branch A Stages 1-3; use the existing research_plan.json and run Stages 4-7 plus Gate 1 |
Branch A: Distillation Pipeline
Source Intake → Intake Assessment → Research Plan Design
→ Research Swarm → Gate 1: Merge
→ Exemplar Discovery → Synthesis (3 agents)
→ Skill Compilation
Core principle: extract the operating system behind the source, not just the content or answer.
A-Stage 1: Source Intake
Input: person, author, method, organization, domain, URL, repo, or local files.
Create package workspace at output/<target-slug>-skill/:
output/<target-slug>-skill/
├── README.md
├── SKILL.md.draft
├── references/ # agent reports + exemplars
├── intermediate/ # structured data
└── examples/ # persona: required; tool: optional
Do not pre-create
templates/; output templates live in LEAP's shared layer and are not needed in the generated skill.
Write intermediate/open_world_task.json with the capability brief g, target,
source-access specification S (allowed source types, retrieval channels, and
exclusions), execution/package constraints C, and depth_level. Every later
retrieval must comply with S; existing skills are not eligible exemplars unless
S explicitly permits them.
depth_level | Effect | Use case |
|---|---|---|
quick | Agent count ≤3 | Rapid prototype |
standard | No correction to auto-assessment | Daily use (default) |
deep | Agent count upper bound +1, capped at 8 | Broader evidence coverage |
A-Stage 2: Intake Assessment
Step 1: Source Modality Analysis
Classify every source by what it can reveal:
| Modality | Examples | Reveals |
|---|---|---|
transcript_interview | podcasts, video captions, Q&A | spontaneous reasoning, analogies, changed positions |
longform_text | books, papers, essays, newsletters | core arguments, methodology, narrative structure |
secondary_criticism | reviews, biographies, analysis | external perspective, blind spots, competing views |
video_subtitle | YouTube, Bilibili captions | speech patterns, unscripted reasoning |
social_media | posts, threads | expression patterns, real-time reactions |
code_repo | git repos, PRs | architecture patterns, API contracts, testing strategy |
For each modality present, note what operations it could reveal. Skip absent ones.
Step 2: Domain Inference
Read domains/<domain>/domain.md to confirm. Record primary + secondary domains.
Step 3: Evidence Depth Assessment
Don't count sources — assess their density.
- ≥3 high-density sources across ≥2 modalities → rich (5-8 agents)
- 1-2 high-density sources → moderate (3-5 agents)
- 0 high-density, all medium/low → sparse (2-3 agents)
Apply depth_level correction: quick→floor+cap at 3, standard→no change,
deep→ceiling+1, cap at 8.
Step 4: Skill Mode Determination
| Target type | Skill mode | Behavior |
|---|---|---|
| Person / author / expert | persona | First-person role-play. Includes Role-Playing Rules, Identity, How I Speak, and Decision Heuristics |
| Domain / method / organization | tool | Third-person analytical. Has Activation Rules, Agentic Protocol, Operation Models |
A-Stage 3: Research Plan Design
How to select candidate operational factors
- Start from Lens's candidate operational factors and acquisition targets. Hidden dimensions, brief-specific values, and matched contrastive tests are one planning mechanism, not separate discovery stages.
- Read primary domain pack:
domains/<primary-domain>/domain.md→ candidate factors - If persona, also read
domains/persona-os/domain.md. This cross-cutting layer provides OS extraction lenses (decision under constraint, failure processing, value conflict resolution, attention allocation, etc.). - Cross factors with source modality: match → active, no match → skip
- Apply evidence depth cap: sparse→merge, moderate→1:1, rich→split
- Derive a new candidate factor only when the source exposes a behavior-relevant distinction not already represented.
For each active factor d, retain or construct a paired acquisition target
<d, x, x'> whose contexts differ along d. Convert it into a focused research
question asking whether the contexts require different treatment in condition,
action, recovery, or verification. A factor is confirmed as an implicit requirement
only when acquired evidence supports such a treatment difference.
Self-Check Before Writing research_plan.json
- Depth match — Does agent_count fall within the depth range?
- Modality coverage — Are source_modalities_used actually present?
- Factor coverage — Does every active factor have a matched acquisition target?
- Merge intent — Deliberate or lazy? Document the rationale.
Search direction must target dilemmas
Good: "What was the hardest decision at [event]? What options did they have?"
Bad: "What is their leadership style?"
Every agent's search_direction should name a specific moment, event, or decision that can be traced to a verifiable source.
Write intermediate/research_plan.json with one record per planned research agent.
Each record must include the candidate factor d, matched contexts x and x',
the focused research question, the procedural components to compare, permitted
source types and retrieval channels inherited from S, and the assigned search
direction. Together these focused questions form Q.
Plan-Only Mode Stop Point
If invoked with stop after Stage 3 or stop_after_stage: 3:
Stop immediately after writing research_plan.json. Output:
Research plan generated and saved to intermediate/research_plan.json.
[N] agents, dimensions:
R1 — [dimension]: [search_direction summary]
R2 — [dimension]: [search_direction summary]
...
Do not enter Stage 4. Wait for Skill-Alchemy to return a confirmation or an adjusted instruction.
A-Stage 4: Research Swarm
Resume mode: If invoked with continue from Stage 4, read the agent
configuration directly from the existing intermediate/research_plan.json.
Skip Stages 1-3.
Launch N agents in parallel. Each agent writes references/R<NN>-<agent_id>.md:
Status: pass (or warning / fail)
## Structured Findings
- Finding ID: stable identifier used by later artifacts
- Acquisition Target: `<factor, x, x'>`
- Context x: seed operating conditions
- Treatment in x: source-grounded behavior, not an executable instruction
- Evidence for x: source_id, type, confidence, and source-stated boundary
- Context x': matched conditions with only the target factor changed
- Treatment in x': source-grounded behavior, not an executable instruction
- Evidence for x': source_id, type, confidence, and source-stated boundary
- Affected Components: condition / action / recovery / verification
- Relation: changed / invariant / unresolved
## Dilemma Decision Cases (≥2 required)
### Case N: [one-line summary]
- Dilemma: specific conflict or hard choice
- Constraints: what limited their options
- Decision Steps: what they did, step by step
- Outcome: what happened
- Extractable Operation: generalizable rule/pattern/heuristic
## Evidence Sources (source_id, type, confidence)
## Supported Candidate Operations
## Rejected or Weak Candidate Operations
## Target-specific Patterns
## Boundaries and Uncertainties
## Recommendations for Later Skill Compilation
Agent Contract: Every report begins with Status: pass / warning / fail.
Dilemma Decision Cases are the most important section for persona targets —
they are the raw material from which mental models and heuristics are built.
Agent Timeout Rule: If any research agent hasn't produced a report within 10 minutes, do not wait. Proceed with completed agents. Gate 1 checks:
- Persona: ≥4 total Dilemma Cases across all completed reports → pass. <4 → downgrade depth to quick and relaunch with fewer (≤2) agents.
- Tool: ≥2 total Dilemma Cases → pass. <2 → same downgrade.
- Mark missing agents in
merge_report.json:"agents_lost": ["R2", "R3"].
A-Gate 1: Research Merge
Agent uses data-analysis skill to process reports:
-
Read all R1-Rn reports
-
Extract Status + all sections
-
Dilemma Case gate: persona targets — per-report 0 cases = warning, combined total <4 = fail
-
Normalize every paired finding into
evidence_matrix.json, retaining both contexts, both treatments, affected components, boundaries, and evidence IDs. -
Write one entry per acquisition target to
contrast_records.json:changed: evidence supports different treatment in at least one component; a source-stated applicability boundary along the target factor is sufficient evidence that the bounded component changes across the matched contexts;invariant: evidence supports the same treatment across non-equivalent contexts;unresolved: either side lacks enough evidence or the comparison conflicts. Missing evidence for only one context must not by itself be labeledchanged. Use this schema:
{ "factor": "d", "context_x": "seed context", "context_x_prime": "matched context with d changed", "component_relations": { "condition": "changed", "action": "invariant", "recovery": "unresolved", "verification": "invariant" }, "evidence_x": ["F01"], "evidence_x_prime": ["F02"], "overall_relation": "changed", "confirmed_implicit_requirement": true, "evidence_stated_boundary": "..." } -
Confirm a factor as an implicit requirement only when its contrast record is
changed. Keepinvariantandunresolvedrecords for later scope decisions. -
Detect cross-report contradictions and write
contradiction_report.jsonandmerge-summary.md. -
Write
merge_report.json,evidence_matrix.json, andcontrast_records.json.
Gate 1 merges and checks research evidence only. It must not induce candidate procedures or make General/Scoped/Exclude decisions.
A-Stage 5: Exemplar Discovery
Retrieve the best exemplars in real time from the public skill pool on skills.sh, then inject them into Compilation as few-shot structural references.
Retrieval Workflow
This stage runs only when existing skills are an allowed source type under S.
Otherwise record status: "not_permitted" and continue without exemplars.
-
Search with find-skills: Call the skills.sh find-skills interface with keywords for the target. Return the top 20 candidate
skill_keyvalues. -
Download candidate SKILL.md files concurrently and score them mechanically:
- Download the SKILL.md files for all 20 candidates concurrently from GitHub raw.
- Run
python3 scripts/score_skill.py --skill <path> --jsonfor each candidate. - Sort by
quality_score: prioritize elite candidates (≥11) and discard drafts (<9).
-
Select and inject the best candidates automatically:
- Take the top 3-5 elite exemplars, prioritizing scores ≥11.
- Write them to
references/exemplars/exemplar-<N>.md. - Write the scoring results to
references/exemplar_candidates.jsonfor audit.
-
Handle cases with no qualified result:
- If every candidate scores below 9, broaden the search terms and search once more.
- If no elite candidate is found after two rounds, set
status: "degraded"inexemplar_discovery.json. - You must still attempt to obtain at least one exemplar. It is the basis for compilation quality.
A-Stage 6: Synthesis
Run the following steps in order. Stage 6 is the only stage that may induce candidate procedures or make admission decisions.
S1: Decision Alignment
Group findings by the procedural decision they inform, not by source topic. Write
operation_candidates.json. Each candidate must have this shape:
{
"candidate_id": "P01",
"decision": "the procedural decision being made",
"condition": {"content": "...", "evidence_ids": ["F01"]},
"action": {"content": "...", "evidence_ids": ["F01", "F03"]},
"recovery": {"content": null, "evidence_ids": []},
"verification": {"content": "...", "evidence_ids": ["F04"]}
}
Leave an unsupported component empty. Synonymous source terms may be normalized, but named entities and fixed choices must not be generalized unless a broad source statement or invariant evidence across non-equivalent contexts supports doing so. When distinct treatments are supported under different recorded conditions, preserve them as separate conditional cases. Do not collapse them into one rule. Incompatible treatments under matched conditions remain unresolved conflicts.
S2: Procedure Admission
For each candidate, write an entry to admission_records.json:
{
"candidate_id": "P01",
"F_plus": ["F01", "F03", "F04"],
"F_minus": [],
"sigma": "widest operating scope supported by the listed evidence",
"supported": true,
"consistent": true,
"reusable": true,
"reuse_basis": "broad_source_statement | cross_context_invariance | none",
"decision": "General",
"rationale": "short evidence-based explanation"
}
Apply these rules exactly:
supported=trueonly when every populated component is backed by evidence that applies withinsigma.consistent=trueonly when noF_minusevidence prescribes incompatible treatment under overlapping conditions withinsigma.- Restrict
sigmabefore classification when support holds only in a narrower scope. reusable=trueonly when an allowed source explicitly states broader applicability or invariant evidence supports the same treatment across at least two non-equivalent contexts. A single source-local case is not reusable.- Classify as
Generalwhen supported, consistent, and reusable;Scopedwhen supported and consistent but not reusable; otherwiseExclude.
Write admitted_general.json, admitted_scoped.json, and
excluded_candidates.json from these records. Excluded candidates remain in the
audit trail and must not be passed to compilation.
S3: Package Design
Write package_plan.json. Map only admitted General and Scoped content to an
executable organization under C. Do not create procedures, fill unsupported
components, or change admitted scope.
A-Stage 7: Skill Compilation
Compile final package from all research + synthesis reports + exemplars.
Compilation Inputs (in Priority Order)
admitted_general.json— the only source of reusable instructions.admitted_scoped.json— the only source of context-bound examples or notes.- Execution and packaging constraints
Cfromopen_world_task.json. skill-grammar.md— MUST be read before rendering. Use its patterns to organize the package, place package-relative references, apply progressive disclosure, and avoid known anti-patterns.- Permitted exemplars, when available, may guide organization and presentation only.
Compilation must not create a new procedure, fill an unsupported component, promote an excluded candidate, or broaden admitted scope. Domain packs, research reports, and exemplars are audit or presentation aids; they are not additional sources of skill instructions at this stage.
Package contents
<skill-name>/
├── SKILL.md # lean entry point — runtime loaded
├── skill.json # metadata (name, version, skill_mode, domain)
├── README.md # storefront (see template in shared layer)
├── references/

├── scripts/ # optional executable routines used by the skill
├── assets/ # optional templates or static resources
├── examples/

└── intermediate/ # pipeline audit trail
Create scripts/, assets/, and examples/ only when the admitted content and C
require them. Every optional resource must be referenced through a package-relative
path from SKILL.md or another reachable package file.
Runtime loads only SKILL.md. The runtime protocol reads
sop_models.mdon demand. R1-Rn andintermediate/are audit artifacts.
A persona MUST include examples/demo_conversation.md with 3-4 scenarios:
common, edge case, and refusal. Missing file → fail.
The examples/ directory is optional for tool mode.
Post-Compilation Cleanup
After compilation, delete temporary artifacts to keep the output clean:
- Delete
references/exemplar_candidates.json—the temporary scoring file has already served its purpose. - Delete
references/exemplars/—the intermediate reference copies have already served their purpose. - Delete empty directories.
- Keep
references/R*.mdas research evidence,intermediate/as the audit trail, and the output package.
Branch B: Fusion Pipeline
method.skill (skeleton) × subject.skill(s) (flesh) → output.skill
WEAVE is not a concatenator. If you can tell where one skill ends and another begins, the weave failed.
B-Step 1: Retrieve Skills
Confirm that every skill required for fusion is ready:
primary: "Interview Techniques" ← workflow skeleton
secondary: ["BeiDou Navigation"] ← style/persona source
depth: "standard"
Retrieve each required skill in this order:
- Local
output/directory (skills generated previously) - Installed skills (
~/.claude/skills/) - find-skills online search (semantic search over the public skills.sh pool)
- GitHub raw download
If a skill does not exist:
- Tell the user which skill must be generated first and recommend Branch A distillation.
- Or ask the user to provide the path to an existing skill.
After retrieving a skill, run
python3 scripts/score_skill.py --skill <path> --json to verify its quality.
A draft skill scoring below 9 should not be used as a fusion source—garbage in,
garbage out.
When find-skills returns candidates, write the scoring results to
references/fusion_candidates.json:
[
{"skill_key": "xxx", "score": 12, "summary": "...", "recommended_role": "primary"},
{"skill_key": "yyy", "score": 9, "summary": "...", "recommended_role": "secondary"}
]
Skill-Alchemy presents these candidates to the user for confirmation. LEAP does not handle the interaction itself.
B-Step 2: Parse
2.1 Parse primary skill (skeleton)
Extract:
- Workflow: every step, in order. Number them.
- Output format: what the skill produces at each step
- Decision points: if-then branches, conditional logic
- Constraints: what this skill cannot/will not do
The primary skill determines the structure of the output.
2.2 Parse secondary skill(s) (flesh)
For each secondary skill, extract:
- Role/persona: how they speak, their identity, their worldview (persona) OR their domain lens, their operation models (tool)
- Style elements: tone, rhythm, vocabulary, forbidden phrases, signature patterns
- Heuristics/decision rules: their falsifiable operating rules
- Constraints: what this skill cannot/will not do
- Evidence anchors: verifiable sources that back their patterns
The secondary skills determine the texture of the output.
B-Step 3: Weave
Fusion depth is controlled by depth_level.
quick — Style Injection
Each style element from secondary skills is injected into the primary workflow at the most relevant step. Minimal rewriting.
Interview Techniques Step 3 "Generate Core Questions"
→ Inject BeiDou Navigation's questioning style: begin with a specific
experience, establish rapport, and then probe further
standard — Structured Weave (default)
-
Rewrite the role. Create a new unified identity.
- Bad: "You are BeiDou Navigation. You are an interviewer."
- Good: "You are a BeiDou Navigation-style interview-planning assistant. You learn and reuse his interview methods without claiming to be him."
-
Weave workflow × style. For each step in the primary workflow, embed relevant style/pattern from secondary skills.
- Each style injection must cite its source skill section.
- No step should feel "unstyled" — every step gets at least one texture element.
-
Merge constraints. Union of all source skill constraints. Remove duplicates. Flag conflicts (if primary says "do X" and secondary says "never do X").
-
Check for gaps. Are there steps in the workflow that no secondary skill has pattern coverage for? Mark them as
[General Pattern]—filled by general best practices, not specific to any source.
deep — Weave + Gap Resolution
Same as standard, plus:
-
Detect conflicts. When two source skills contradict on a point, resolve explicitly. Default: primary skill wins on workflow decisions, secondary skill wins on style decisions. Document every conflict and resolution.
-
Fill gaps. For steps marked
[General Pattern], launch a lightweight research agent to find domain-specific patterns. -
Source traceability. Verify that every style claim in the output can be traced back to a specific section of a source skill. Verify that no constraint was dropped.
B-Step 4: Output
Generate output.skill using the SKILL.md templates in the shared layer below.
Role naming convention
- "BeiDou Navigation-style Interview-Planning Assistant"—"style" indicates derivation rather than identity.
- "Decision Framework Based on Zhang Yiming's Product Philosophy"—"based on" indicates the source.
