name: map-method
description: >
  Static mapping and standalone navigation of existing map evidence.
  TRIGGER WHEN: project questions, unfamiliar code, debugging, feature work, refactors, reviews or documentation. Consult map evidence before broad exploration. Loading the skill starts no analysis or refresh. Verify claims against source; search the repository without usable maps.
  DO NOT TRIGGER WHEN: no project code or documentation.

> `<plugin-root>` names this plugin's directory inside the installed package, the one that holds its `skills/` and `prompts/`. Resolve it once from where this file was loaded, then substitute it into every path below that starts with it.
> This plugin declares an MCP server, `codebase-map`, started with `uv run --no-config --no-project --script <plugin-root>/skills/map-method/scripts/mcp_server.py`. This host does not start a plugin-declared MCP server on its own. Before calling this server's tools, register that command under that name in the host's MCP configuration and verify the connection. Pi has no MCP client of its own: install `pi-mcp-adapter` (`pi install npm:pi-mcp-adapter`), then add that command under that name to the `mcpServers` object of `~/.config/mcp/mcp.json`, or of any other file that extension reads (`.mcp.json` in the project, `<pi agent dir>/mcp.json`, `.pi/mcp.json`). Resolve the plugin root to an absolute path when you write it there, because that file is read outside this session.

<daodan_host_binding host="pi">
This binding governs execution of this package and its loaded references. It takes
precedence over executable examples written for another host. Use only registered
tools and their actual input schema; an example never creates a tool, argument,
permission, model alias or nested worker capability. Preserve the generated worker
allowlist, dependency closure, scope and delivery contracts.

Pi binding: repository reads use read/find/grep, writes use edit/write, and shell
execution uses bash or the registered powershell alternative. Use their actual
command, timeout and process-control schema rather than capitalized foreign tools.
Core Pi supplies neither subagent nor MCP. Isolated workers require pi-subagents:
pi install npm:pi-subagents. Use that extension's registered subagent schema and
pass the full rendered role body inline. Role skills named <plugin>-<role> are
body resources with automatic invocation disabled, not a built-in named agent.
Workflow prompt entries use /<plugin>-<workflow>; ordinary skills use their exact
registered names. If isolation is mandatory and unavailable, stop the phase.
MCP requires pi-mcp-adapter: pi install npm:pi-mcp-adapter, then register the
generated server command in its supported MCP configuration.
Keep the selected package's full local dependency closure. Provision qualified
foreign providers as skills/resources this runtime can load; Pi does not install
another host's marketplace plugin from a Claude install command.
Inherit the active session's model and default variant. A source model alias such
as sonnet is not a portable override; request a different model only through an
explicit adapter mapping to a valid host identity and user authorization.
Kernel <owner>:<skill> references identify the logical provider. Ordinary Pi
skills retain their source frontmatter name, so resolve the actual registered name
and provider path from the active inventory; do not invent a prefixed native ID.

The executing agent and its coordinator own continuation, recovery, verification
and delivery. Skills supply knowledge and method instructions; they are not
executors or a runtime persistence mechanism.

Resolve each component by kind and exact installed identity. A role is dispatched
as a worker, a skill loads instructions, and a workflow starts its declared method.
Kernel owner-qualified skill references are logical provider identities: resolve
them to the actual host registry name and verified installed provider path. Do not
invent a registry string by adding an owner's prefix when the host does not use it.
Do not load an agent identity as a skill or execute a workflow name as a shell
command. Declared required foreign providers remain mandatory. If a required
provider or capability (including required MCP access or isolation) is unavailable,
stop its dependent phase and report the missing capability. Optional external
providers follow the method's declared selection and absence behavior; their
absence alone does not block the base workflow. Report any explicitly requested
but unavailable provider contribution as unfulfilled and continue independent
work. Do not install a different host's plugin or
substitute unrelated skills to claim coverage.

Shell execution alone does not establish interactive stdin. Before a capture or
checkpoint, use an available session-control mechanism. When stdin is unavailable,
keep user-driven capture in a supported background process with bounded output and
an explicit stop signal controlled by the coordinator after the user's completion
message. Close owned browser/process resources on completion or cancellation.

Continue working within the current authorization while the requested result is
achievable. After a tool error, inspect its cause, correct the relevant input or
implementation, retry when justified and verify the outcome; never repeat a
failing action blindly. Do not close the turn with a promise or a partial result
when an authorized next step can still produce or verify the requested result.
Stop only for a documented real impediment, a missing required capability, an
unresolved human decision or the caller's stop request. At that boundary, report
completed results, remaining work and the concrete prerequisite for continuation;
continue any independent work that the blocker does not prevent.

A tool's successful exit, a worker stop or an idle session is not the deliverable.
Return final text naming observed findings, artifact paths, executed checks and
blockers. An empty worker result is missing delivery: inspect or resume that worker
when permitted, or record failure. Verify required artifacts and candidate gates
before marking the requested outcome complete.

This is an execution binding, not a rewrite of source examples. Preserve programming
language fences, domain code and host APIs that are the subject of marketplace-ops
or agent-sdk-builder. A host-as-subject API is not a tool provided to this session.
Compiled binding and static checks do not prove an installed host executed a run.

# Codebase Map Analysis Skill

## Language Support

| Language | Extensions | Structural extraction | Comment syntax |
|---|---|---|---|
| Python | `.py`, `.pyi` | stdlib `ast` (always available) | `#` line + docstrings |
| Java | `.java` | tree-sitter (preferred) or regex | `//`, `/* */`, Javadoc `/** */` |
| JavaScript | `.js`, `.mjs`, `.cjs`, `.jsx` | tree-sitter (preferred) or regex | `//`, `/* */`, JSDoc `/** */` |
| TypeScript | `.ts`, `.tsx`, `.mts`, `.cts` | tree-sitter (preferred) or regex; adds interfaces, enums, type aliases | `//`, `/* */`, JSDoc `/** */` |
| SQL | `.sql`, `.ddl`, `.dml` | regex DDL (tables, views, indexes, sequences, types, functions, procedures, triggers) | `--`, `/* */` |
| PL/SQL (Oracle) | `.pks`, `.pkb`, `.plsql`, `.pls`, `.pck`, `.prc`, `.fnc`, `.trg` | regex (packages, package bodies, type bodies, cursors, exceptions, %TYPE/%ROWTYPE references) | `--`, `/* */` |
| Rust | `.rs` | tree-sitter (preferred) or regex; structs, enums, traits, impls (with `Trait for Type` naming), mods, unions, type aliases | `//`, `/* */`, rustdoc `///` / `//!` / `/** */` / `/*! */` |
| Go | `.go` | tree-sitter (preferred) or regex; functions, methods, types | `//`, `/* */` |
| CSS, SCSS, LESS | `.css`, `.scss`, `.less` | stdlib tokenizer, never tree-sitter; one symbol per applied rule (flattened selector within enclosing at-rules); top-level at-rules, Sass/LESS variables, mixins, Sass functions; `@import`/`@use`/`@forward`; Tailwind `@apply` layout utilities expanded as declarations | `/* */`, and `//` outside plain CSS |

`.sql` is disambiguated against PL/SQL by Oracle-specific content markers (`languages/__init__.py`); `plpgsql` stays SQL.

## How This Skill Is Invoked

`references/entry-analyze.md` dispatches isolated `codebase-map:map-analyst`;
`references/entry-team-analyze.md` uses isolated partition workers. Entries own
`.codebase-map/` publication (`references/run.md`).
Loading `codebase-map:map-method` starts no analysis or run.

## Load map

| Unit | Holds | Loaded by |
|---|---|---|
| `references/run.md` | classic/team runs, concurrency and perimeter | whoever owns the run |
| `references/snapshot.md` | snapshot ownership, scope, write, diff, carry and check commands | whoever owns the run's snapshot |
| `references/update.md` | incremental re-derivation | analyst on accepted updates |
| `references/deepen.md` | cards an area lacks | area deepening; analyst in `cards` mode |
| `references/evidence.md` | evidence, forbidden files, commands, source reading, classification; maintained-document verification separately | every phase worker and every consumer that reads source |
| `references/reading.md` | analysis reading | every consumer of a bound analysis |
| `references/standalone.md` | shared read-only map discovery, navigation, impact and fallback | every map consumer, including analysis and composed workflows |
| `references/locate.md` | the measured loop for finding the code a request is about: search by name, expand with outline and graph, read by symbol, reproduce, then fix | every agent that changes code with a map |
| `references/phase-0.md` | Phase 0 knowledge discovery | analyst and team entry |
| `references/phases-1-2.md` | Phase 1 structure, Phase 2 interfaces | phase 1 and 2 workers |
| `references/phases-3-4.md` | Phase 3 flows, Phase 4 semantics and the analysis loop | phase 3 and 4 workers |
| `references/phases-5-6.md` | Phase 5 patterns and risks, Phase 6 documentation health | phase 5 and 6 workers |
| `references/phase-7.md` | Phase 7 final report | analyst and synthesizer |

## Consumer map

- Every map consumer, including analyze and composed workflows: `references/standalone.md` and `references/reading.md` section `Task views`. Ordinary standalone source reads add `references/evidence.md` sections `CRITICAL PRINCIPLE: EVIDENCE-ANCHORED OUTPUT` and `Forbidden Files`; composed consumers keep their own authorized evidence and producer procedures.
- Forbidden files: `references/evidence.md`.
- Consuming a bound analysis: `references/reading.md`, plus `references/evidence.md` before Maintained documentation for source. For durable-document verification, read its Maintained documentation section. Snapshot verification/refresh uses `references/snapshot.md` before Prerequisites.
- Run analyses through `references/entry-analyze.md`; composed callers declare isolated `codebase-map/map-analyst`.

## Team bindings

Use canonical skeletons in owned output. Put partition identity below titles, never in headings. Workers and synthesizers do not update classic state.

## Method loads

Conditional reads: methodology, patterns, comments. Follow nested loads; count their union with core reads.

| Resource | Sections | When |
|---|---|---|
| `references/AI_ANALYSIS_METHODOLOGY.md` | all | methodology |
| `references/SEMANTIC_PATTERNS.md` | all | patterns |
| `references/ANTIREZ_COMMENTING_STANDARDS.md` | all | comments |
